Ouman FLEX UI8 Universal Input Module — Modbus RTU, 8 Universal Inputs

DIN-rail RS-485 I/O expansion module for building automation systems

Overview

This is an Ouman FLEX UI8, a DIN-rail mounted universal input module that connects to an RS-485 bus using the Modbus RTU protocol. Providing 8 universal measurement inputs, it's designed as an I/O expansion device for Ouman building automation controllers such as the Ouflex A series, letting a single system acquire a wide range of sensor and signal types across a distributed field wiring layout.

Key Features

  • 8 universal measurement inputs: Each input can be individually configured for voltage, current, passive sensor, contact, or pulse-counting signal types.
  • Voltage and current signal support: Accepts standard 0-10V voltage transmitters and 0/4-20mA current transmitters.
  • Broad passive sensor compatibility: Supports NTC10, NTC1.8, NTC2.2, NTC20, Ni 1000 LG, Ni 1000 DIN 43760, and Pt 1000 temperature sensor types.
  • Contact and pulse input support: Reads opening/closing contact status and counts pulses (minimum 30 ms pulse length) for applications like flow measurement.
  • Modbus RTU over RS-485: Reliable, fast data transmission integrating easily into existing Modbus-based building automation networks.
  • Compact DIN-rail housing: Space-saving 4-module (71 x 91 x 59 mm) enclosure for straightforward cabinet installation.
