4 channel BCD signal controlled relay board module. Decodes BCD (binary) signals injected to the input to control the corresponding mains rated relay output. Ideal for applications requiring a large number of outputs controlled from a few control signals.
Includes a "Latch" or "Strobe" function which allows multiplexed control of several modules with a single BCD code. The board also features an inhibit input.
An LED indicates each relays status. The power input has reverse polarity protection. Screw terminal blocks for all connections.
