Product Snapshot

6ES7231-0HC22-0XA8 is the EM 231 4-channel analog input expansion for S7-200 CN CPUs. It converts 4 differential voltage or current signals into 12-bit digital values, making it the most cost-effective way to add temperature, pressure, level or flow inputs to any micro-PLC system.

Key Features & Benefits

4 differential AI - isolated channel-to-channel
12-bit + sign resolution - 0.1 % accuracy, ±0.2 % full-scale
Software-selectable ranges - 0-20 mA, 4-20 mA, ±5 V, ±10 V, 0-10 V per channel
On-board 24 V sensor supply - 60 mA, short-circuit protected
DIP-free configuration - range set in CPU configuration byte
Ultra-slim - 71 mm width, 62 mm depth, DIN-rail snap-on
Wide temperature - 0 - 55 °C operating, -40 - +70 °C storage
Global approvals - CE, UL 508, CSA, FM Class 1 Div 2, RoHS, REACH
