905U-L I/O Count Transmitter and Receiver Pair

Product catalog summary

Overview
The ELPRO 905U-L is an industrial wireless I/O solution designed for performance, integrity, and security. It offers a small I/O capability suitable for simple one-way communication links and can be configured as part of a larger wireless network. The system supports up to 3000 wireless units per network and features secure data encryption.

Transmitter Unit (905U-L-T)
The transmitter operates on a 900MHz frequency with a 1W power output. It includes two digital/pulse inputs, one analog input, and one thermocouple mV input. The unit can internally calculate values such as setpoint status and pulse count. It features cold-junction compensation for thermocouples and provides local output for setpoint status.

Receiver Unit (905U-L-R)
The receiver unit offers three digital contact outputs and one analog output. It includes communication failure indication and configurable outputs that can be retained or reset in case of failure. LED indicators provide radio signal strength feedback.

Standards Compliance
The system complies with various radio, EMC, and electrical standards, including EN 300 220, FCC Part 15, and Class 1 Div 2 hazardous area approval.

General Specifications
The units operate in temperatures ranging from -40 to 60°C and are housed in a DIN-rail thermo-plastic enclosure. Power supply requirements are 9-30 VDC, with specific power consumption rates for transmitter and receiver units.

Inputs and Outputs
Transmitter inputs include digital/pulse and analog inputs, with configurable spans and zero settings. The receiver outputs include digital relay contacts and analog outputs, with fail-safe configurations available.

Wireless Communication
The system uses frequency hopping spread spectrum technology, with a line-of-sight range of up to 20 miles. Communication is facilitated by the ELPRO WIB-net protocol, supporting peer-to-peer communications and secure data encryption.

Configuration and Diagnostics
Units are factory-configured as matched pairs but can be user-configured via a serial port. Diagnostic features include reading input values, writing output values, and monitoring communication messages.
