These software-configurable modules handle a wide variety of signal levels. They provide high resolution (0.004% of nominal range) for precise signal levels, as well as multiple-channel packaging. All SNAP analog modules are factory calibrated and individually tested. Part numbers ending in -FM are Factory Mutual approved. SNAP analog input modules have an on-board microprocessor to provide module-level intelligence, which makes them an ideal choice for Original Equipment Manufacturers (OEMs). For additional information about the standalone operation of SNAP analog modules, see Opto 22 form #0876, SNAP I/O Module Integration Guide. Isolation All SNAP analog input modules are isolated from all other modules and from the SNAP I/O processor.

DATA SHEET Form 1065-190329 PAGE 2 in this data sheet do not have channel-to-channel isolation, however. (If you need isolated analog modules, see Opto 22 form #1182.) Transformer isolation prevents ground loop currents from flowing between field devices and causing noise that produces erroneous readings. Ground loop currents are caused when two grounded field devices share a connection, and the ground potential at each device is different. Isolation also protects sensitive control electronics from industrial field signals. IMPORTANT: Since these analog input modules provide multiple single-ended input channels with a common reference, the channels are not isolated from each other. (See Opto 22 form #1182 for isolated modules.) Bipolar and Unipolar Input Modules Most SNAP analog input modules are considered to be bipolar, which means the range extends equal amounts above and below zero. An example of this is the SNAP-AIV module, which has a range of -10 to +10 VDC. Some modules are considered unipolar, which means the range starts or ends at zero. For example, the SNAP-AIVRMS module has a range of 0 to 250 VAC because AC current cannot be negative. Nominal Range and Over-range Limits All SNAP analog input modules have a nominal range for the field signal and most support a 10% over-range limit. The nominal range is the normal range of the field signal for the module or point configuration. The over-range limit is the maximum valid field signal the module or point configuration can read outside of the nominal range. For example, the over-range limits for the SNAP-AIV are -11 and +11 VDC, and for the SNAP-AIVRMS, the over-range limit is 275 VAC. Some modules or point configurations do not support field signals outside of the nominal range. For example, points configured as temperature inputs (thermocouple, RTD, ICTD) do not support over-range readings. When the field signal is outside of the over-range limits of the module, the brain will not be able to determine if the value is too high or too low, so it will return an "out of range" value of -32768.0 Over-range limits only apply to input modules. Output modules are limited to their nominal ranges. OPTO 22 * 800-321-6786 * 1-951-695-3000 * www.opto22.com * sales@opto22.com (c) 2001-2019 Opto 22. All rights reserved.

Two- and four-channel modules (except the SNAP-AIRTD-10 and SNAP-AIRTD-1K) can also be used with legacy SNAP M-series and B-series mounting racks. (For more information on using legacy hardware, see form #1688, the SNAP PAC System Migration Technical Note.) Modules snap securely into place in the row of connectors on the mounting rack. Each module connector has a number. Analog input modules and other types of SNAP I/O modules are mounted on the module connectors starting at module position zero. Modules require a special tool (provided) for removal. Module position zero Module connectors Retention bar 1. Place the rack so that the module connector numbers are right-side up, with zero on the left, as shown in the diagram above. (If your rack has screw connectors, the screw connectors will be at the bottom.) 2. Position the module over the module connector, aligning the small slot at the base of the module with the retention bar on the rack. When positioning modules next to each other, be sure to align the male and female module keys at the tops of the modules before snapping a module into position. 3. With the module correctly aligned, push on the module to snap it into place. 4. Use standard 4-40 x 1/2 truss-head Phillips hold-down screws to secure both sides of each module. CAUTION: Do not over-tighten screws. See Specifications. 5. Follow the wiring diagrams beginning on page 4 to attach modules to the devices they monitor. Most modules accept 22 to 14 AWG wire; the SNAP-AITM-8 accepts a maximum of two solid 18 AWG wires. For faster, easier field wiring installation and maintenance, use SNAP TEX cables and breakout boards. See Opto 22 form #1756, the SNAP TEX Cables & Breakout Boards Data Sheet, for compatibility and specifications.

DATA SHEET Form 1065-190329 PAGE 11 Wiring Correcting for Inverted Scaling SNAP TEX cables and a breakout rack are available separately for wiring points to field devices (see form #1756, the SNAP TEX Cables & Breakout Boards Data Sheet). The SNAP-HD-BF6 cable connects the module to the breakout rack, which can then be wired to field devices. (NOTE: The SNAP-HD-CBF6 wiring harness with flying leads is not recommended for this module.) Positive readings for these modules appear as negative values. Therefore, in order to obtain meaningful readings, use the scaling feature in PAC Control as follows: 1. In the Add or Edit Analog Point dialog box for each point, choose the scalable version of the module. 2. Under Scaling, scale each point negatively as shown below: CAUTION: We strongly recommend that you use the breakout rack with these modules. Miswiring of any point on the module can cause severe out-of-warranty damage. The breakout rack protects the module from many wiring errors. if you are using the module with loop power (2-wire) negative common devices, connect to the SNAP-AIMA-HDB (or -FM) rack. If you are using the module with self-powered devices (4-wire) or with devices that share a common positive connection, do not use the SNAP-AIMA-HDB (or -FM) boards, which have a current limiting diode. Instead, wire to the SNAP-AIV-HDB or SNAP-AIV-HDB-FM. OPTO 22 * 800-321-6786 * 1-951-695-3000 * www.opto22.com * sales@opto22.com (c) 2001-2019 Opto 22. All rights reserved.

DATA SHEET Form 1065-190329 PAGE 18 THERMISTOR INPUT MODULE 0-400 K (CONTINUED) Auto-range Curves The following table shows temperatures in C and F that correlate with resistance values in Ohms for the generic curve types for four popular thermistors using the Steinhart-Hart equation. Choose the curve type for your application in PAC Control or PAC Manager when you configure a SNAP-AIR400K-8 module. (For custom curves, see page 19.) Choose a 2-wire thermistor value with a resistance over the target temperature range that is much larger than the lead resistance for your application Lower value curves (2252 or 3K) work best at cooler temperatures (< 25 C or 77 F) because long lead wire resistance can add significant errors to the measurement.

You can individually configure each of the module's 8 points for a variety of behaviors: * Temperature--Range is fixed. Default range is 0-8000 ohms. Choose nickel, platinum, or copper RTD input. The data returned is degrees C or degrees F, depending on your choice for the I/O unit. * Fixed-range (default)--Choose the range you want to use. If the value goes above the limit for that range, an out-of-range value (16-bit) of -32768 is displayed. The data returned is resistance in ohms. * Full Auto-range--The module scrolls up and down the entire set of ranges and dynamically chooses the appropriate range for best resolution. Note that this point type can result in higher latency when ranging up (see Specifications on next page). The data returned is resistance in ohms. * Auto-range Down--The module scrolls down and up within the specified range limit. If the value goes above the specified range, an out-of-range value (16-bit) of -32768 is displayed. These point types allow auto-ranging within the selected range but limit the data latency when ranging up. The data returned is resistance in ohms.
