10 relay NO/NC output SMD receiving unit for DIN rail

This new DIN‐Rail Receiver offers three operating modes. Basically, the receiver incorporates 10 relays which can be controlled through the 40 MHz, 433,9 2MHz and 868,5 MHz SMD handheld transmitters.

The 868,5 MHz Band is supported out of the box and the other two with one of the matching extension modules. On valid reception of a handheld transmitter signal, the rx LED flashes.

The receiver needs a 12 – 24V AC or DC power supply. It should at least be able to source approximately
250 mA of current. There are 10 relays on the board which can be controlled by radio. Four (R1, R2, R3 and R4) of them
offer a toggle switch and the others (R5, R6, R7, R8, R9 and R10) are closing switches.

They all can be connected to a common connecter COM through solder bridges on the backside of the board, right
beneath the associated relay (except for R9 and R10) which shall be connected to COM. These solder
bridges are marked in Figure 1 by an orange rectangle around them. It’s recommended to use 0‐Ohm
resistors to close this connection if the COM line is used. Each relay has an LED associated to it which
shows the status. When the relay is set its LED illuminates and when it is cleared the LED is turned off.
Nominal switching capacity (resistive load) of R1 through R4 is 6A 250V AC, their max. switching power
(resistive load) is 1500VA.

Nominal switching capacity (resistive load) of R5 through R10 is 5A 250V AC / 5A 30V DC, their max.
switching power (resistive load) is 1250VA, 150W.
