SOLID STATE RELAYS FOR INTRINSIC SAFETY SBG Series Starts at ADVANTAGES OF OMEGA® SOLID STATE RELAYS: ߜ Rapid, Arc-Free Response for Positive, Non-Mechanical Operation ߜ Solid State Reliability Ensures Consistent Performance ߜ Low-Power Switching where a Few Milliamps of Current Control High-Power Loads ߜ Encapsulated Construction— Impervious to Dust, Moisture, and Foreign Material ߜ Standardized, Modular Housings for Easier Installation ߜ Exceptionally Long, Trouble-Free Service Life SBG22445, $182, shown smaller than actual size. hazardous area to safely control higher-power AC loads in the non-hazardous area. Typical applications include flow, level, and pressure switches, which may be inputs to an alarm or control system. Dimensional Data Solid State Relay: Less than 100 µA at 14 Vdc actuates the unit to control AC loads to 5 A at 120 Vac. Resistive (up to 400,000 Ω) or short-circuiting sensors operate the unit. There are 115 Vac and 230 Vac models. Latching Solid State Relay: The 115 Vac model has momentary actuation, “start-stop” or differential control switching for resistive loads to 0.3 A.
