4-Channel Analog Input:Provides 4 single-ended analog input channels, ideal for connecting various field sensors and transmitters to monitor process variables.
Voltage & Current Signal Support:Each channel is configurable for standard 0–10 V / ±10 V voltage or 0–20 mA / 4–20 mA current input, offering flexibility for diverse industrial instrumentation.
High Accuracy with 12-Bit Resolution:Features a 12-bit A/D converter to ensure precise and stable signal acquisition, enhancing control system performance.
Isolated Design:Electrical isolation between the input channels and backplane bus reduces noise interference and improves electromagnetic compatibility (EMC), ensuring reliable operation.
Plug-and-Play Installation:As a standard expansion module for S7-200 SMART CPUs, it connects directly to the right side of the CPU, supports DIN-rail mounting, and is automatically recognized—no additional configuration required.
Compatible with Transmitter Signals Only:This module accepts only standard voltage/current signals from transmitters; for direct thermocouple or RTD input, use dedicated temperature modules (e.g., EM AT04).
