Features:
Module uses high quality relay, normally open interface maximum load:AC 250V/10A, DC 30V/10A.
SMD optical coupler isolation, strong driving ability, stable performance; trigger current 5mA.
Module can set high level or low level trigger by jumper.
Fault-tolerant design, even if the control wire is broken, relay will not move.
Equipped with power indicator light (green) and relay status indicator light (red).
Better interface design, all interfaces can be wired directly by terminal, very convenient.
Designed with four fixing bolt hole of 3mm diameter and 45mm*40mm spacing.

Relay Output:
1, NO1: 1-channel relay normally open interface, relay are disconnected before energized, and connected to COM1 after energized.
2, COM1: 1-channel relay COM interface
3, NC1: 1-channel relay normally closed interface, connected to COM1 before relay is energized, and disconnected after relay is energized.
4, NO2: 2-channel relay normally open interface, disconnected before relay is energized, and connected to COM2 after relay is energized.
5, COM2: 2-channel relay COM interface
6, NC2: 2-channel relay normally closed interface, connected to COM2 before relay is energized, and disconnected after relay is energized.
High and low level trigger option end:
1. S 1 is 1-channel relay high and low level trigger option;
2. S 2 is 2-channel relay high and low level trigger option;
3. When com and low are connected, the corresponding relay is low level trigger; when com and high are connected, it is high level trigger.

Package Includes:
1 x Relay Module
