OMEGA®SOLID STATE RELAYS FOR INTRINSIC SAFETY
The maximum energy possible at the switch terminals of the OMEGA Solid-State Relays is far below the explosive point of the most volatile surrounding gas conditions. The type of non-voltage-producing switch or sensor best fitted for the application can be utilized, since the entire switching circuit is rendered intrinsically safe by the OMEGA®Solid-State Relay. As the switching circuit is low voltage, there is no shock hazard to operating or maintenance personnel.

Installation and Maintenance
OMEGA®Solid-State Relays units are normally installed in a safe area and connected to the sensor in a hazardous location; no explosion-proof or protective housings of any kind are are needed. Units install singly in any position, or can be grouped on a common earth-grounded plate with mounting tabs to provide electrical grounding. No. 6-32 threaded electrical terminals are conveniently placed atop the unit housings.

Note: Zener barrier model numbers SBG54803 and SBG54806 are certified by CSA for mounting inside a suitable enclosure in Div. 2 or non-hazardous locations and must be connected by means of the 2 studs provided to a grounded copper busbar or equivalent.

OMEGA®zener barriers must be installed in conformance with the National Electrical Code and the Instruction, Installation and Service Bulletin supplied with all units. Periodic checks of ground bonding and cleanliness of units and terminals constitute the only maintenance required.

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 ) 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. OMEGA for intrinsic safety allow non-voltage producing switches mounted in the hazardous area to safely control higher-power AC loads in the
