Intrinsically SAFE-PAK(R) 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 100,000 ) or short-circuiting sensors operate the unit. 120 VAC and 240 VAC model. Low Sensitivity SAFE-PAK: Sensor closures up to 1000 resistance control resistive loads to 5A at 120 VAC. 120 VAC, N.O. model.
