105U-1,2,3,4 Wireless IO

The ELPRO multi-I/O products are two-way communication devices which transmit signal values by radio (specifying the value and I/O output channel) to a receiving module. The receiving module then decodes the message, generating/re-creating the value at the specified I/O channel outputs. ELPRO 105U series products have four differing I/O versions and can multi-hop repeat five times. When combined with ELPRO’s 115S series products or gateway products, the 105U series can accommodate changing I/O and data-bus/protocol requirements.
