These systems enable one-way transmission of 8 digital states or 4 analogical quantities over 400 metres.
In DIGITAL version, the transmitter is provided with 8 digital inputs to 8 "open collector" outputs or 4 relay outputs.
In ANALOGICAL version, the 4 outputs copy the value of the corresponding input. This is a 4-channel / 8-bit system, with 0-5 V voltages or 0-20 mA currents.
The receiver is on continuous listen and periodically changes channel in the same way as the transmitter. The link is addressed and is made on 3 channels.
7 groups of 3 channels are available.
The applications covered range from information transfer, remote controls, to triggering security systems… in sectors of activity such as automation, robotics, remote management… |
