Elpro 905U-L Transmitter & Receiver I/O Pair

Elpro 905U-L Transmitter & Receiver I/O Pair. Just connect the antennas and apply power for them to be operational. Limited stock available of this legacy product.

The Elpro 905U-L is a pre-configured wireless transmitter and receiver I/O pair: connect the antennas, apply power and it is working. It uses licence-free 900 MHz frequency-hopping radio at 1 W, with a typical line-of-sight range of up to 15 km, and is part of our wireless and IoT range.

The transmitter takes two digital or pulse inputs, one 4–20 mA input and one thermocouple or mV input, and the receiver reproduces them as three relay outputs and one analogue output. It suits tank level and pump control, bore monitoring and cable replacement across roads and rivers. This is a legacy product with limited stock; see the 905U-L datasheet.
