Internal Design and Analog Conversion

This analog input module uses a 12-bit ADC for signal conversion. A multiplexer scans all eight channels sequentially for processing. The ABB 1SAP245000R0001 configures each channel independently for current or voltage. Eight 0.1 µF capacitors filter high-frequency noise from input signals. Consequently, this module delivers accurate analog readings for process control applications.

Installation and Wiring Guide

First, mount this module onto a standard 35 mm DIN rail securely. Next, wire your analog sensors to the input terminals (channels 1-8). Use shielded twisted-pair cables for all analog signal connections. Configure each channel’s input type using AC500 configuration software. The module provides a green LED for status indication. This analog input module works with all AC500 CPU models including 1SAP140200R0160 and 1SAP140300R0160. Always connect the shield drain wire to earth ground for noise reduction.
