I/O MODULES G4 QUADRATURE DATA SHEET Form 548-040728 Description page 1/4 Part Numbers G4IDC5Q Description G4 DC Input, 4-16 VDC, 5 VDC Logic, 2-Channel Quadrature The G4IDC5Q quadrature input module pair is designed to allow a digital mistic 200 multi-function I/O Brick to resolve positional information from quadrature encoder devices. The module will output a pulse to the Brick each quadrature state changes. The Brick will count the module outputs and keep track of direction of rotation.

The active output is determined by the direction of rotation of the encoder. One 0.8 microsecond pulse is output for each change of quadrature state transition. The actual resolution of the position count is 4 times the encoder resolution (pulses per revolution). The G4IDC5Q is actually a pair of modules, one of which is labeled "A", the other "B". When the signal into the module A leads the signal into module B, the output will be on module A. When the signal into module B leads the signal into module A, the output will be on module B. On a Digital mistic 200 I/O Unit, quadrature input channels must be configured in pairs, with the lower channel number being even. Therefore the only quadrature pairs allowed are channels 0 & 1, 2 & 3, 4 & 5, 6 & 7, 8 & 9,, 10 & 11, 12 & 13, and 14 & 15. The positional count will increment when the signal into the odd numbered channel leads the signal into the even numbered channel. It will decrement when the signal into the even numbered channel leads the signal into the odd numbered channel. Since the Digital mistic 200 I/O Unit has a maximum input frequency, 50% duty cycle, of 12.5 KHz, as shown in the specifications below, then: Maximum Allowable Encoder RPM (at 50% duty cycle) = 12,000 pulses/sec X encoder pulses/rev 60 sec 1 minute Specifications Logic Voltage 5 VDC Operating Ambient Temperature -30 C to 70 C Isolation input-to-output 4,000 VRMS Input Voltage Range 4-16 VDC Input Current 8 mA (constant) Input Allowed for No Output 1V Logic Supply Current @ 5 VDC 60 mA Maximum Input Frequency, 50% Duty Cycle 12.5 kHz Minimum Time Between Quadrature State Changes at 90 20 sec Opto 22 * 43044 Business Park Drive * Temecula, CA 92590 * Phone: (951) 695-3000 * (800) 321-OPTO * Fax: (951) 695-3095 * www.opto22.com Inside Sales: (800) 321-OPTO * Product Support: (800) TEK-OPTO * (951) 695-3080 * Fax: (951) 695-3017 * Email: support@opto22.com I/O MODULES G4 QUADRATURE DATA SHEET page 3/4 Form 548-040728 Connection Diagram Opto 22 * 43044 Business Park Drive * Temecula, CA 92590 * Phone: (951) 695-3000 * (800) 321-OPTO * Fax: (951) 695-3095 * www.opto22.com Inside Sales: (800) 321-OPTO * Product Support: (800) TEK-OPTO * (951) 695-3080 * Fax: (951) 695-3017 * Email: support@opto22.com (c) 1991-2004 Opto 22.

LATEST PRODUCTS PRODUCT SUPPORT COMPANY INFORMATION I/O MODULES G4 QUADRATURE Products DATA SHEET Opto 22 produces a broad array of reliable, flexible hardware and Form 548-040728 software products for industrial automation, remote monitoring, enterprise data acquisition, and machine-to-machine (M2M) applications. SNAP Ethernet Systems Based on the Internet Protocol (IP), SNAP Ethernet systems offer flexibility in their network connectivity and in the software applications they work with. The physical network may be a wired Ethernet network, a cellular wireless network, or a modem. A wide variety of software applications can exchange data with SNAP Ethernet systems, including: * Opto 22's own ioProjectTM suite of control and HMI software * Manufacturing resource planning (MRP), enterprise management, and other enterprise systems * Human-machine interfaces (HMIs) * Databases * Email systems * OPC client software * Custom applications * Modbus/TCP software and hardware. SNAP Ethernet system hardware consists of controllers and I/O units. Controllers provide central control and data distribution. I/O units provide local connection to sensors and equipment. SNAP OEM Systems Opto 22 SNAP OEM I/O systems are highly configurable, programmable processors intended for OEMs, IT professionals, and others who need to use custom software with Opto 22 SNAP I/O modules. Linux(R) applications running on these systems can read and write to analog, simple digital, and serial I/O points on SNAP I/O modules using easily implemented file-based operations. Applications can be developed using several common development tools and environments, including C or C++, Java, and shell scripts. M2M Systems Machine-to-machine (M2M) systems connect your business computer systems to the machines, devices, and environments you want to monitor, control, or collect data from. M2M systems often use wireless cellular communications to link remote facilities to central systems over the Internet, or to provide monitoring and control capability via a cellular phone. Opto 22's NvioTM systems include everything you need for M2M-- interface and communications hardware, data service plan, and Web portal--in one easy-to-use package. Visit nvio.opto22.com for more information. Opto 22 Software Opto 22's ioProject and FactoryFloor(R) software suites provide full-featured and cost-effective control, HMI, and OPC software to power your Opto 22 hardware.
