Intrinsically Safe Pak Relay For Hazardous Environments With Low Current Actuation 100 To 135 VAC Load Up To 5 A 9 VDC Activation 120 VAC Switching Resistive Loads Up To 100 K Ohms 0 To 120 F Operating Temperature Gems Sensors Model 25872
✔️ Single unit, 9 VDC actuation; 120 VAC up to 5 A
Gems intrinsically Safe-Pak electronic relay lets you safely switch 120 VAC loads in hazardous environments using a tiny 9 VDC control signal. It’s a handy fit for industrial plants, oil and gas facilities, and other safety-critical settings that require intrinsic safety approvals. Operating temperature: 0 to 120 °F (−18 to 49 °C).
✅ Less than 100 microamps at 9 VDC actuates the unit
✅ Switches loads up to 5 A at 120 VAC (resistive)
✅ SPST N.O. switching
✅ Output leakage current: 6 mA max at 120 VAC
✅ Turn-on sensitivity: 400 KΩ (typical); turn-off: 1 MΩ (typical)
✅ Sensor compatibility: resistive loads up to 100 kΩ or sensor short-circuit
✅ Height: 3 in (76 mm)
✅ Approvals: UL, FM, CSA
💡 What is an intrinsically safe Pak relay used for in hazardous environments? It provides safe remote control of mains loads with very limited energy. - Handy for controlling pumps and heaters in gas or dust zones. - Low input current makes it easy to drive from small controllers. - UL, FM, CSA approvals help meet strict safety standards. - Operates safely across a wide temperature range from 0 to 120 °F.
