Custom chip of microprocessor LSI circuit.
Approx. 1 second.
* Input : one pulse per revolution, ≥ 60 RPM
Two relays: Relay 1; Control relay, Relay 2; Alarm relay
Max Load: 0.5 ACA/250 ACV 0.5 DCA/24 DCV
Note: Do not apply a load current that exceeds 0.5A. Large
currents will damage the relay and also void the warranty.
