105U-L I/O Count Transmitter and Receiver Pair

The ELPRO 105U-L-T (Transmitter) and 105U-L-R (Receiver) products feature a small I/O count, one-way and cost-effective communications between field devices.

The 105U-L series products are flexible by design (i.e., pre-configured pairs for ease of commissioning) and may be used in simple to complex, multi-hop repeating networks (in combination with other ELPRO I/O and gateway products).

Description

Applications:

 

Flow meter monitoring, Storage tank monitoring, Pipeline cathodic protection, Pump stop-start, Lighting bank control, Power reticulation relay fault notifications, Emergency shower notification, Weather station reporting, Bearing condition monitoring

 

Transmitter
