- Datasheet

The ELPRO 105U-L and 905U-L products are a small I/O count transmitter and receiver pair delivered pre-configured for ease of installation. Just connect the antennas and apply power for them to be operational.  The L series products may be reconfigured into a wider ELPRO I/O or gateway network as application needs grow. DIN rail mounted and DC (9-30V) powered, the units can also power a loop powered device to 24VDC, 30mA.


Flexible usage: pre-configured matched transmitter/ receiver pair; individual use for transmission/ receiving I/O from other devices

Peer-to-peer communications with exception reporting, self-checking of messages via update time and secure data encryption

Multi-hop repeatability of signals when used with multi-I/O and gateway units
