105U-L I/O Count Transmitter

Key Features:

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).

•869.525MHz/500mW or 869.875MHz/5mW frequency options.
•Flexible usage: pre-configured matched transmitter/receiver pair or complex networks via ELPRO I/O and/or Gateway products.
• Peer-to-peer communications with exception reporting, self-checking of messages via CRC, update time and secure data encryption.
• Multi-hop repeatability via ELPRO multi-I/O & Gateways products.
