Intrinsically SAFE-PAK® Relays Amplify
Sensor Load-Handling Capabilities
Costly explosion-proof enclosures with their mounting requirements are unnecessary.
No purging is required.
SAFE-PAK: Less than 100 microamps at 9 VDC actuates the unit to control loads to
5A at 120 VAC. Resistive (up to 100,000Ω ) or short-circuiting sensors operate the
unit. 120 VAC and 240 VAC model.
Low Sensitivity SAFE-PAK: Sensor closures up to 1000Ω resistance control resistive
loads to 5A at 120 VAC. 120 VAC, N.O. model.
See table on Page L-2 for specific approval information.

with sensor switch in hazardous location.
Transient Protection for SAFE-PAK (AC Loads) Use a properly sized
metal oxide varistor (MOV) as shown below.
Installation and maintenance must be in accordance with the National Electrical
Code and the applicable GEMS INSTRUCTION, INSTALLATION and SERVICE bulletin
available at www.gemssensors.com
