S109 Datasheet | Solid State Optronic

Zero Cross 800V / 0.8A AC Solid State Relay Description The S109 is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay. The circuit is posed of one input IR LED which activates an optically coupled IC on the output that controls the firing angle of two back-to-back SCRs. This circuit assures no false triggering under most adverse conditions, and a tight zerovolt switching window not exceeding 5V. The S109 provides high peak load voltage (800V+) and high input-tooutput isolation voltage (up to 5kVRMS). The S109 es in a pact 6 pin DIP package, making it ideal for high-density board applications. Applications - Valve Control - Solenoid...
