Description
Product Description
8 channel relay module photoelectric isolation control board single PLC control
1. This product is replaced with a new original Matsukawa relay (833H-1C-C).
2, input signal compatible with NPN and PNP.
3, each relay is provided with a group of normally open and normally closed.
4. Each input terminal adopts photoelectric isolation module to effectively protect the safety of the control terminal; It is also equipped with eight bipolar status indicators.
5, Wiring: VCC and GND are the power supply ports of this module, and wiring is according to the marked voltage. COM is connected to the common pole of the signal control end, and 1-8 is connected to each control signal; Controlled electrical output normally closed normally open symbol display, at a glance.
6, the use of large current terminal, can control 220V 10A (maximum) load.
External electrical connection diagram of the module (This module can control electrical appliances with voltages below 250V and 10A, the following takes the control of 220V AC electrical appliances as an example) : 1, manual control:
