UN 331-1KF02-0AB0 Unimat – analogue input module SM331, 8AI, U/I/RTD, 13 bit, UN300

UN 331-1KF02-0AB0 is an analogue input module of the UN300 series with 8 channels for voltage, current, resistance and RTD signals. It is a component of the series UniMAT UN300 designed for industrial control systems, machine modernisation, switchboards and distributed I/O assemblies.

The product is suitable for universal acquisition of analogue values from voltage, current and temperature sensors in industrial automation. When choosing, it is important to compare the full order number, number of channels, signal type, supply, connector and the parameters of the specific PLC project.

Typical applications

Universal acquisition of analogue values from voltage, current and temperature sensors in industrial automation. The module can be used when building a new control system as well as when servicing and modernising existing automation, provided the electrical and system parameters meet the application requirements.

Technical specifications

Wiring and integration into the PLC assembly

The specific channel wiring depends on the selected measuring range – voltage, current, resistance or RTD. Use a 40-pin front connector and shielded wiring; before commissioning, the module setting must match the type of connected signal.

Compatibility and choosing a replacement

The manufacturer lists UN 331-1KF02-0AB0 as an analogue input module of the UN300 series compatible with the Siemens architecture S7-300. When replacing, verify the signal ranges and channel configuration.

When replacing an existing module, a similar name is not enough. Compare the full order number, number and type of I/O, voltage and current levels, resolution, connector, wiring, parameterisation and support in the PLC configuration used.
