BACHMANN AIO208 AIO216 Universal Analog Input/Output Module
The AIO208 and AIO216 modules 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. 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 cost-effective solution that simplifies logistics and servicing. Different modes can be combined and set simply using a configuration wizard in the SolutionCenter engineering tool.
