4 bidirectional channel Radio Remote Control SRR4
The best solutions for the transmission of signals between electrical panels. PLL Radio Transmission
SRR4 Remote control
The Radio Control SRR4 has been specifically designed for industrial applications where it is not possible to make a connection through the cable or the distance between the equipment that must interact with each other and it constitutes an excessive use of labor work for laying cables.
With the devices SRR4 is possible to perform the transmission of signals through relay contacts in input and in output from both sides up to 4 channels.
Once powered, the 2 units are coupled automatically by activating its own continuous transmission security (TX continues just on SRR4 868) and a green LED located on the front, which, lighting, determines proper operation.
From this time forward, the closure of one or more inputs on a device SRR4 with their common, activate the output to a relay contact in the corresponding unit SRR4 coupled.
In a situation of radio interference, excessive increase in the operating range of the devices, or simply loss of power on the part of one of the 2 units, you will have the decoupling of the units that will shut down the green LED and red LED error. In SRR4 device 868 will also disable all signals with the fall of the output relays active.
