Product Features

Bi-directional isolated 2-Channel relay control module, according to user needs, select the high or low level to control the relay pull. Module working voltage: DC5V .Normally open interface maximum load: AC 250V / 10A, DC 30V / 10A; The use of high-quality ultra-small bi-directional isolated optocoupler, stable performance; trigger current only 3mA; Users can choose the control level of the relay, which can be high-level pull-in or low-level pull-in. The module contains a current-limiting resistor, which can be directly controlled by the positive and negative polarity of the power supply, and can also use I / O port control Fault-tolerant design, the relay does not operate even if the control line is off; power indicator (red), 2 relay status indicator (blue).
