16Channel Plc Amplifier Board Isolation Relay Board Input NPN Output NPN 1236V DC.Feature: 1. Isolate and amplify the weak control signal (only a few milliamps of current) by photoelectricity, and finally output a higher power control signal to directly drive the motor, contactor, solenoid valve, etc. 2. The response time is as low as milliseconds and there is no limit on the number of switches. It can directly replace traditional relays, reducing maintenance time and costs. 3. Photoelectric iso
