The UR20-4AI-UI-16-DIAG (order no. 1315690000) is a u-remote 4-channel analogue input module with 16-bit resolution and an accuracy of 0.1% FSR. Each of its four inputs can be parameterised for voltage (0-5 V, 0-10 V, 1-5 V, 2-10 V, ±10 V) or current (0-20 mA or 4-20 mA) measurement, with 2-wire, 3-wire or 3-wire + FE sensor connection, and each channel has its own status LED. Sensor supply is available on each channel (0-750 mA), conversion time is 1 ms, and the module provides individual channel diagnosis on each of its four channels. It measures 76 x 120 x 11.5 mm, weighs 89 g, and operates from -20°C to 60°C.

Weidmüller's u-remote analogue input modules are available in variants with 12- and 16-bit resolution, recording up to four analogue sensors with maximum accuracy across voltage or current ranges, with the measurement range individually configurable per channel. A separate 16-bit variant is available for current measurement from up to eight sensors at a time. The module electronics supply the connected sensors with power from the input current path. It is RoHS conformant and holds cULus (E141197) and cULusEX (E223527) certification, and supports PROFINET IRT/RT, PROFIBUS DP-V1, EtherCAT, Modbus/TCP, EtherNet/IP, CANopen, DeviceNet, POWERLINK, CC-Link, CC-Link IE TSN and IEC 61162-450 fieldbus protocols.
