Bachmann AIO288 Analog Input/Output Module

The Bachmann AIO288 is a high-precision, multifunctional analog module engineered for the M1 automation system. This unit integrates eight analog input channels and eight analog output channels within a single compact housing. It manages a diverse range of signal types, including voltage, current, and resistance, providing a centralized solution for interfacing with industrial sensors and actuators. Because the module supports both single-ended and differential input modes, it effectively minimizes electrical noise interference in complex wiring environments.

Specialized Sensor Support and Diagnostics

Beyond standard analog signals, the AIO288 offers dedicated support for temperature and position sensing. The module accommodates up to four Pt100 or Pt1000 RTD sensors using either 2-wire or 4-wire connection methods. Furthermore, it provides an integrated power supply for up to four potentiometers. To ensure maximum system uptime, Bachmann has equipped this module with advanced diagnostic features. These include automatic wire break detection for voltage inputs and overload protection for potentiometer supplies. Consequently, maintenance teams can identify field-side wiring faults immediately without extensive manual testing.
