Solid-State Relays for Intrinsic Safety
SBG22445A,SBG25872A,SBG25873A,SBG41705A
PLACE ORDER - Rapid, Arc-Free Response for Positive, Non-Mechanical Operation
- Solid-State Reliability to Insure Consistent Performance
- Low-Power Switching where a Few Milliamps of Current Control High-Power Loads
- Completely Encapsulated Construction Impervious to Dust, Moisture or Foreign Material
- Standardized, Modular Housings for Easier Installation
- Exceptionally Long, Trouble-Free Service Life
- Latching and Non-Latching Models
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.
