16-Way Relay Control Module/Isolated Expansion Module/High/Low Level Trigger/5V/12V/24V

16-Way Relay Control Module/Isolated Expansion Module/High/Low Level Trigger/5V/12V/24V Beskrivelse

Isolated 16-way relay control module, select high-level or low-level signal trigger, only 5mA current can drive the relay with a control ability of 10A, the module adopts high-quality power relay, small package optocoupler, high power High voltage triode, signal indicator, grade double-sided PCB board, comprehensive board layout, stable performance, can be widely used in various power control occasions.
Increase the power supply anti-reverse connection function, the wrong power supply will not damage the module; fault-tolerant design, the control is broken, the relay will not act;
The module adopts high-quality relays, normally open interface load: AC 250V/10A, 30V/10A;
Using high-quality small two-way isolation optocoupler, strong anti-interference ability, stable performance; trigger current only needs 5mA;
The working voltage of the module is 12V, 16 modules

The user can select the control level of the relay, which can be high-level pull-in or low-level pull-in; the module has a built-in current limiting resistor, which can be directly controlled by the positive and negative poles of the power supply, or the I /O port control;
Power indicator 16-way relay status indicator ()
The interface design is user-friendly, all interfaces can be directly connected through the terminal block, which is very convenient
There are 4 3mm fixing bolt holes for easy installation
Two module interface
Module control terminal: 19-wire interface, all interfaces have wiring terminals, which is convenient for users to wire
1. +: The positive pole of an external power supply (12V)
2. -: External power supply negative
3. XM: common terminal of photoelectric isolation chip
If high level control is adopted: this signal should be connected to the negative pole of the power supply of the user
