Each channel of the module can be triggered by a jumper to set a high level or a low level; 5, Fault-tolerant design, even if the control line is disconnected, the relay will not move; 6. With status indicator: power (green), 4-channel relay status indicator (red) 7. All module size interfaces can be directly connected through the terminal block, which is convenient and practical. 8, module size: 108mm * 50mm * 18.6mm (length * width * height) 9, with 4 fixing bolt holes, hole 3.1mm, spacing 6.8cm*4.4cm
Module interface: 1. DC+: Connect to the positive of the power supply. 2. DC-: Connect the negative of the power supply. 3. IN1-IN4: According to the setting of each channel, the corresponding relay can be controlled by high or low level.
Relay output: 1, NO1--NO4: Relay normally open interface. 2, COM1--COM4 relay common interface 3. NC1--NC4: Relay normally closed interface.
High and low trigger selection: 1.S1-S4 are the high and low level trigger selections of relays 1 to 4 in sequence; 2. When COM and LOW connected, the corresponding relay is triggered by low level, and when COM and HIGH connected, it is triggered by high level.
