Bachmann|AIO208| Analog I/O Module
Description
The Bachmann AIO208 is a universal analog input/output module with 8 configurable channels, designed for precise measurement and control of voltage, current, and temperature signals in industrial automation systems.
Features
- 8 multifunctional analog channels
- Supports voltage, current, Pt sensors, and thermocouples
- Dual-mode configuration per channel for flexible signal handling
- High-resolution 16-bit input and 14-bit output
- Adjustable filtering (4 kHz to 0.5 Hz) per channel
- Electrical isolation up to 500 V
- ColdClimate version available (AIO208 CC)
Technical Specifications
General Design
- Channels: 8 (configurable as input or output)
- Resolution:
- Inputs: 16 bits with filter
- Outputs: 14 bits
- Filter frequency: Adjustable per channel from 4 kHz to 0.5 Hz
- Overload, short-circuit, and reverse polarity protection
- Measurement range monitoring: ±105% adjustable
Signal Types
- Voltage input: ±10 V to ±10 mV
- Current input: 0(4) to 20 mA
- Temperature input: Pt100/Pt1000 (2-/3-/4-wire), thermocouples (J, K, T, N, E, R, S, B)
- Voltage output: ±10 V
- Current output: 0(4) to 20 mA
Electrical Performance
