Quad Relay 20Amp • 120/240 Vac • AC Output Four independent AC output relays come in a single standard panel-mount package. Utilizing an AC switch output with internal snubber, relays provide greater protection against false triggering. Model choices include zero-voltage or random turn-on (phase controllable) switching. Manufactured in Crydom's ISO 9001 Certified facility for optimum product performance and reliability. • Zero Voltage and Random Turn-On Swi tching • Triac Output • Industry Standard Package • Panel M ount MODEL NUMBER T D2420Q OUTPUT SPECIFICATIONS ➀ Operating Voltage (47-63 Hz) [Vrms] 24-280 Load Current Range ➂ [Arms] .15-20 Transient Overvoltage [Vpk] 600 Max.
