Isolated Type 16 Channel Relay Module Interface Board High/Low Level Trigger (DC 5V)

Features 1.With power supply reverse connection function to prevent damaging the module. 2.The module uses genuine high-quality relay, rated load of normally open interface: AC 250V/10A, DC 30V/10A. 3.Using small-sized two-way isolated optocoupler, with strong anti-interference ability and stable performance; trigger current is only 5mA. 4.Users can select the control level of the relay, which can be high level pull-in or low level pull-in. 5.The module has built-in finite current resistor. The positive and negative pole control of the power supply can be used directly, or use the I/O port of the single-chip to control. Specification Isolation Type 16 Channel Relay Module can select high-level or low-level signal triggering, and only needs 5mA current to drive the relay with 10A control capability to pull in. The module adopts genuine high-quality power relay, high-quality small-sized package optocoupler, high-power high dielectric strength triode, red and blue signal indicator, military-grade double-sided PCB board, and with reasonable layout and stable performance, can be widely used in a variety pf powers control.
