16 Channel Relay Module Isolated Type Interface Board High/Low Level Trigger DC 5/12/24V(DC12V)

USED DIRECTLY-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. HIGH-QUALITY RELAY-The module uses genuine high-quality relay, rated load of normally open interface: AC 250V/10A, DC 30V/10A. STABLE PERFORMANCE-Using small-sized two-way isolated optocoupler, with strong anti-interference ability and stable performance; trigger current is only 5mA. USING TIPS-Users can select the control level of the relay, which can be high level pull-in or low level pull-in. POWER SUPPLY REVERSE-With power supply reverse connection function to prevent damaging the module.
