Page 13: Wiring Guide
Taking ADC1 as an example, the wiring diagram of analog signal input is as follows: 3.1.2 DI The ED-CM4IND contains 2 isolated DI interfaces. There are two wiring methods for the digital input signals, dry contact (passive) wiring and wet contact (active) wiring. - Page 14 The connection diagram of PNP type sensor is as follows. If you do not use an external power supply to power the sensor, you can use the Vout provided by ED-CM4IND for power supply. The connection diagram for PNP type sensors using Vout power supply is as follows: Vout can only provide 12V power output.
- Page 15 If you do not use an external power supply to power the sensor, you can use the Vout provided by ED-CM4IND for power supply. The connection diagram for NPN type sensors using Vout power supply is as follows: Vout can only provide 12V power output.
- Page 16 ED-CM4IND 3.1.3 Realy The relay output interfaces NC, COM, NO, correspond to the normally closed, common, and normally open of the relays respectively, and the relays of ED-CM4IND are double-knife, double- throw relays. • When the control relay is closed, NO1 and NO2 are closed with respect to COM1 and COM2.

- Page 27 GPIO 26: level=0 fsel=0 func=INPUT pull=DOWN 4.15 Relay The ED-CM4IND features an onboard double-pole double-throw (DPDT) relay, controlled by the GPIO22 pin's high or low level. By default, the relay is in the normally closed (NC) state, where COM1 is connected to NC1 and COM2 is connected to NC2. When GPIO22 is set to a high level, the relay switches to the open state, connecting COM1 to NO1 and COM2 to NO2.
