The insulated type 16 channel relay module allows you to choose a high or low level signal trigger and only the current required to drive a relay with 10A control function for retraction.
This module adopts a genuine high quality power relay, high quality small package optocampuler, high power high dielectric strength triode, red and blue signal indicator, military grade double sided PCB board, with reasonable layout and stable performance. Widely used with various PF power control.
Function:
1.Power reverse connection function to prevent damage to the module
2. The module uses genuine high quality relay, normal open interface rated load (AC 250V/10A, DC 30V/10A).
3. Use small bi-directional insulated photo coupler with strong anti-interference ability and stable performance. Trigger current is only 5mA.
4. User can choose the control level of relay Control level is high level pull-in or low level pull-in.
5. The module has a limited current resistance. You can use the power source positive and negative polarity control directly, or use the single chip I/O port.
6. Power Indicator(red), Relay Status Indicator (blue)
7. User-friendly interface design,
