Product catalog summary

General Specifications
The ELPRO 905U-K is a wireless I/O module designed for remote monitoring of process signals. It operates in temperatures from -40 to 140ºF (-40 to 60ºC) and humidity levels from 0 to 99% RH. The module is housed in a NEMA 4/IP66 painted aluminum enclosure, providing weatherproof protection. It complies with EMC standards such as FCC Part 15, AS3548, and EN 300 683.

Power Supply and Consumption
The module requires a 6 - 30 VDC power supply, with low power consumption in sleep mode (<140µA) and during operation (<10mA at 12VDC). It includes an internal 24VDC loop supply and monitors supply voltage, which can be transmitted as discrete or analog inputs.

Inputs and Outputs
The 905U-K supports two discrete or pulse inputs and one analog input. Discrete inputs can handle voltage-free contacts or TTL signals, while pulse inputs support up to 10 KHz. The analog input is selectable between 0-24mA or 0-10V, with 12-bit resolution and user calibration options.

Radio Transmitter
The module features a 900MHz frequency-hopping radio transmitter operating on a license-free band, with a range of over 20 miles (30km). It supports up to five repeaters to extend range and can transmit messages multiple times for reliability.

Configuration and Diagnostics
The module includes a Windows configuration package and an RS232 serial port for diagnostics. It supports error-checking in transmission messages and can be configured to repeat transmissions.

Applications
The 905U-K is suitable for utility industries like electricity, water, and gas, as well as factory and plant monitoring. It is compatible with the 905U range of products, allowing integration with PLCs, DCS, or PCs.

Power Efficiency
Designed for low power consumption, the 905U-K can operate on ELPRO BU-5 battery packs for over a year, depending on configuration. It features an internal alarm for low supply voltage, which can be transmitted by radio.

General Information
The ELPRO 905U-K is a wireless I/O module designed for process monitoring applications. It operates within a temperature range of -40 to 140ºF (-40 to 60ºC) and 0 - 99% relative humidity. The device is housed in a NEMA 4 / IP66 painted aluminum enclosure, ensuring durability and weather resistance. It features a weatherproof connector for external connections and an SMA connector for antenna or coaxial cable connection.

Battery Pack
The BU-5 battery pack consists of 6 x AA alkaline batteries, providing a 9V supply with a service life of up to 1.4 years, depending on input configuration.

Compliance and Approvals
The ELPRO 905U-K is ISO 9001 certified and complies with various electrical safety standards, including CSA US & CSA Canada. It is pending approval for Class 1 Div 2.
