Bachmann AIM112 Analog Input Module (Multi)

Modern automation solutions are highly dependent on pre

cise, fast and robust sensors with an analog interface. The

wide range of interfaces required for integration can be

challenging here. This is especially the case when a large

number of different interfaces requires a correspondingly

large variety of types of acquisition modules.

This is a challenge that the AIM112 type modules meet very

easily. Up to 12 analog inputs can be individually config

ured to the desired signal type. The modules provide both

the common standard signals for current loops (4 mA to

20 mA, ±20 mA) and 4 high-impedance voltage measuring

ranges (±10 V to ±10 mV), each adapted to the conversion

range. Alternatively, channel types for all industrially rele

vant thermocouples including integrated characteristic lin

earization are available for measuring very wide tempera

ture ranges.

Precise signal conversion is possible with a 16‑bit resolu

tion and at very high sampling rates thanks to the special

measurement electronics. Widely adjustable filter chains,

precisely tuned to the signal path, ensure a configurable

balance between interference suppression and measure

ment dynamics. A hardware-accelerated high-speed inter

polation that can be activated as required provides contin

uous measurement signals independent of the filter set

tings and even with very short bus cycles.
