Description

Module description:
1. This module complies with international safety standards, and the control area and the load area have isolation slots;
2, the use of double-sided FR-4 circuit board design, high-end patch production;
3, using genuine relay control;
4, with relay action indication, the suction is bright, the disconnection is not bright;
5. When the signal input terminal has a low-level signal, the common terminal and the normally open terminal will be turned on;
6, the relay can directly control various equipment and load;
7, there are 8 normally open and 8 normally closed contacts;
8. The blue KF301 terminal is more convenient to connect to the control line.
9, Module size: 138m * 56mm * 18.5mm (length * width * height), Net Weight: 120g
10, with 4 fixing bolt holes, hole 3.1mm, spacing 131mm*49.5mm
11, the finished product passed 100% functional test and stability test

Two module interface:
1, VCC: connected to the positive pole of 12V power supply
2, GND: connect the negative pole of 12V power supply
3, IN1-IN8: signal trigger terminal, active low
Relay output: 12-line interface, all interfaces can be directly connected to facilitate user access
1, NO1–NO8: relay normally-open interface, the relay is suspended before the suction, short-circuit with COM after the suction
2, COM1–COM8 relay common interface
3, NC1–NC8: relay normally closed interface, short-circuit with COM before the pull-in of the relay and float after the suction
