Enables one-way transmission of 8 digital states or 4 analogue quantities over 400m. In the Digital version, the transmitter is provided with 8 digital inputs to 8 "open collector" outputs or 4 relay outputs. In the Analogue 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. It complies with the European standard RTTE EN300-220 / EN301-489 and is available in an IP65 enclosure ready for approved use.
