Description

Description

Solid-State Relay:
Less than 100 microamps at 14 Vdc actuates the unit to control ac loadsto 5 amps at 120 Vac. Resistive (up to 400,000 ohms) or short-circuitingsensors operate the unit. 115 Vac and 230 Vac models.

Latching Solid-State Relay:
Momentary actuation, “start-stop” or differential control switching forresistive loads to 0.3 amps, 115 Vac model. trodeks® solid-state relaysfor intrinsic safety allow non-voltage producing switches mounted in thehazardous area to safely control higher power ac loads in the nonhazardousarea. Typical applications include flow, level and pressure switches whichmay be inputs to an alarm or control system.
