ACCESSORIES
Digital IO Board 4 Relays (DIO-004)
Description
The DIO-004 is a four-relay digital IO board specifically designed for the Comset CM685V-1, CM685V-4, CM685V-6 and CM770W-6-G 3G/4G/4GX Routers, as well as the CM685VX and CM950W 5G Routers. It allows controlling larger loads and devices such as a pump, a fan or an air conditioner via SMS.
The DIO-004 requires 12VDC to operate properly. The power supply can be the same as the CM685 router.

- Onboard LED’s to show power status and relay status (relays 1-4).
- Fully assembled.
- Module size: 73mm * 50mm* 18.5mm.
Module interface specifications:
- DC+ : DC power supply positive pole (12VDC)
- DC- : DC power supply negative pole (GND)
- IN1~IN4 : relay signal triggering pin (DIO00~DIO03)
Relay output:
- Normally closed pins (NC1~NC4) : relay normally closed pins
- Common pins (COM1~COM4) : relay common pins
- Normally open pins (NO1~NO4) : relay normally open pins
High or low level trigger option:
- S1~S4:Option switch for relays 1~4;
- Low level trigger if COM pin connects to LOW pin; High level trigger if COM pin connects to High pin
Note: To configure SMS on the router that will allow you to remotely control the DIO board via SMS, please refer to the FAQ page.
