Information

Overview Manuals Common Applications Product Precautions

The AIO216modules enable the measuring or output of all standard analog signals. The AIO208 offers 8 channels and the AIO216 16 channels compactly in a single module. The standard signal types for current (0 to 20 mA and 4 to 20 mA) and voltage ranges (±10 V to ±10 mV) allow the connection of a wide range of sensors and actuators. A minimum 14 bit resolution makes it possible to also measure signals that do not fully utilize the measuring range (e.g. 0 to 5 V) with a sufficiently high resolution.

All outputs overload, short circuit and external voltageproof
Measuring range monitoring freely adjustable (±105 %)
Error message on overload and overtemperature and undervoltage of the supply

Temperatures are playing an important role in an increasing number of processes. These modules therefore also support Pt100/Pt1000 in 2-, 3- and 4-wire measuring circuits, as well as all standard thermocouples. For each channel, a second channel with unused signal types can be used in addition to the primary configured signal type. For example, a current output can be assigned to a voltage input so that up to twice the number of channels per module are provided. This enables one module to cover virtually all analog signal measuring tasks instead of having to use many different modules for each signal type. A costeffective solution that simplifies logistics and servicing. Different modes can be combined and set simply using a configuration wizard in the SolutionCenter engineering tool.

Wind Power Industry

Acquiring hydraulic cylinder position signals from wind turbine pitch systems, and monitoring Pt100/Pt1000 temperatures of generator windings and main bearings.

Metallurgy and Steel Industry

Monitoring high temperatures inside blast furnaces and heat-treatment furnaces via thermocouple sensors, and outputting 4-20mA signals to control gas valve openings.

Oil and Gas Extraction

Connecting pressure transmitters and flow meters (±10V/4-20mA) on oil pipelines to achieve real-time pressure monitoring and overpressure alarming for long-distance pipelines.

Rail Transportation Industry

Monitoring the operating temperatures of electric locomotive transformers and traction motors, and transmitting pneumatic analog signals from braking systems to the main control unit.

Thermal Power and Heating Systems

Monitoring boiler steam pipeline pressure and superheated steam temperature, and outputting current signals to adjust feedwater pump inverter frequencies.

Paper and Printing Industry

Acquiring analog signals from tension sensors and outputting proportional control voltages to adjust rewinder motor torque.

When using the Bachmann AIO216 module, channel modes including current, voltage, or resistance must be correctly configured in the software to avoid incorrect signal sourcing, and analog lines must use shielded twisted-pairs with single-point grounding at the cabinet side to prevent EMI. Furthermore, 3-wire or 4-wire connections are recommended for RTDs to compensate for lead resistance, and lastly, any module swapping or rewiring must be performed under complete power-off conditions with proper ESD protection.

Technical notes

AIO216 is a 16-channel compact analog input/output module featuring 500 V system galvanic isolation. The hardware supports independent per-channel configuration, handling ±10V to ±10mV voltage, 0(4) to 20mA current, 2/3/4-wire Pt100/Pt1000 RTDs, and 8 standard thermocouple types across all input and output signal ranges, while allowing dual-signal mapping per channel to achieve double the density. It features a high data resolution of 16-bit input (with adjustable filtering from 4kHz to 0.5Hz) and 14-bit output, where all output terminals maintain overload, short-circuit, and external voltage proof characteristics, supporting adjustable ±105% range monitoring and autonomous error reporting upon supply undervoltage, overload, or overtemperature, with an optional ColdClimate condensation-proof variant available.
