4-channel receiver – SHR-12 L4
The SHR-12 L4 receiver evaluates every wireless signal from the matching transmitters in the SH-12 wireless series and can switch one or more of the 4 floating changeover contacts on and/or off. The relay functions (toggle and key operation) can be set separately for each output.

In order to carry out a command from a transmitter, it must first be taught. Teaching of a transmitter is carried out very easily by means of a button. As required, up to 60 transmitters can be taught with all keys or individual transmission keys. The particular highlight of the SH-12 wireless series is the feedback from the receiver. You can see from the transmitter whether the wireless communication was successful and receive information about the quality of the transmission path. This feedback can also be switched off for special applications.
The assignment of the functions that the transmission keys or transmission commands are intended to actuate is fix. Both normally open and normally closed contacts are available for connection. LEDs provide information about the function and transmission behaviour and indicate the status of the power supply.
The relay functions can be set separately for each output with the help of jumpers.
Key operation: Input and output behave identically. The output is active only as long as ON is being transmitted.
Toggle operation: A command activates the output continuously. The same command deactivates the output again, and so on.
SHR-12 L4 is supplied with an IP54 housing and an integrated antenna and is fully ready to connect up. By fitting an external or remote antenna, the long range of the receiver can be extended even further. With our BNC connection option (item no.: 00069.05), we will fit a BNC connection in the factory in accordance with the housing protection class. If installation is to be carried out after delivery, the BNC connection kit (item no.: 00069.02) can also be used for self-assembly. It is then possible simply to plug in one of the external antennas from our range of accessories. The BNC connection set (item no.: 00069.01) also allows the antenna to be set up remotely in the optimal position.
The receivers in the SH-12 wireless series have extremely low interference because of their special transmission properties. With wireless transmission that is immune to interference and offers extremely short response times, ranges over 1000 m can be achieved. For strong, narrow-band interference or use of several parallel wireless systems, the working frequency can be set to meet individual needs. The receivers are given a serial number in the factory. This provides greater security and turns every transmitter into a unique device that can be distinguished easily.
We will be happy to advise you on the selection of appropriate transmitters.
