China 12-Way Relay Module Bidirectional Optocoupler High Low Level Trigger Two-Way Optical Isolation 5V 12V 24

12-way relay module / bidirectional optocoupler / high / low level trigger / two-way optical isolation / 5V / 12V / 24
Description:
The isolated 12-channel relay control module can select high-level or low-level signal triggering. It only needs 5mA current to drive the relay with 10A control capability. The module uses genuine high-quality power relay, high-quality small package optocoupler. High-power high-voltage triode, red and blue signal indicator, military-grade double-sided PCB board, comprehensive consideration of layout,stable performance, can be widely used in various power control applications.
Module description:
1. Increase the anti-reverse function of the power supply. If the wrong power supply is connected, the module will not be damaged; the fault-tolerant design, the control line is broken, and the relay will not operate;
2, the module uses genuine high-quality relay, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A;
3, using high-quality small two-way isolated optocoupler, strong anti-interference ability, stable performance; trigger current only needs 5mA;
4, the module working voltage is available for 5V, 12V, 24V; another 4, 8, 12, 16 modules are available;
5, the user can choose the control level of the relay, which can be high level pull-in or low level pull-in; the module has built-in finite current resistor, can directly use the positive and negative control of the power supply, or can use the single-chip I /O port control;
6, power indicator (red), 12 relay status indicator (blue)
7, the interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient
8, module size:12cm * 9cm * 2cm(length * width * height)
9, with 4 3mm fixing bolt holes for easy installation
Module interface:
Module control terminal: 15 wire interface, all interfaces have terminal blocks, convenient for user wiring
1. DC+: External DC power supply positive (5V, 12V and 24V modules are available)
2, DC-: external DC power supply negative
3. XM: Photoelectric isolation chip common terminal
-----If high level control is used: this signal should be connected to the negative terminal of the user control board power supply.
-----If low level control is used: this signal should be connected to the positive side of the user control board power supply.
4, X1-X12: relay control interface,
-----If the XM is connected to the negative pole of the power supply: this port is high (relative to XM) when the corresponding relay is engaged
-----If the XM is connected to the positive pole of the power supply: this port is low (relative to XM) when the corresponding relay is engaged
Note: The isolated relay module is designed to adapt to the harsh electromagnetic environment or high signal requirements. If you want to achieve complete isolation, the power of the user control board (that is, the reference power supply connected to XM) and the power supply of the relay module. (DC+/DC-) should be distinguished.
Relay output: 36-wire interface, all interfaces have terminal blocks for user wiring
1. NO1--NO12: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.
2, COM1--COM12: relay common interface
3. NC1--NC12: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.
