Solid-State Relays for Intrinsic Safety Model SBG22445,SBG25872,SBG25873,SBG41705
Solid-State Relay:
Less than 100 microamps at 14 Vdc actuates the unit to control ac loads to 5 amps at 120 Vac. Resistive (up to 400,000 ohms) or short-circuiting sensors operate the unit. 115 Vac and 230 Vac models.
Latching Solid-State Relay:
Momentary actuation, “start-stop” or differential control switching for resistive loads to 0.3 amps, 115 Vac model. OMEGA® solid-state relays for intrinsic safety allow non-voltage producing switches mounted in the hazardous area to safely control higher power ac loads in the nonhazardous area. Typical applications include flow, level and pressure switches which may be inputs to an alarm or control system.
