Siemens PLC I/O Module, Analogue Input Type, 8 Inputs - SIMATIC Series - 6ES7231-5PF32-0XB0


Do you need to take precise temperature readings during your industrial automation processes? Opt for this PLC I/O module from Siemens. Its a resistance temperature detector with eight resistance thermometer inputs that support copper, nickel and platinum sensing elements to deliver a wide measurement range from -200°C to +850°C. To enable an attached PLC to respond to temperature data, this module converts the analogue input signal to a digital value. Use it with a Siemens SIMATIC S7-1200 series CPU to put together a modular PLC system that meets your needs.

• 15-bit+ sign resolution offers a high level of accuracy

• Operating temperature range of -40°C to +70°C for use in extreme environments

• IP20 rating indicates the unit is safe to touch

• LED indicators and integrated diagnostics functions simplify fault detection for straightforward maintenance

How does an RTD work?


An RTD like this one uses the principle of temperature resistivity. As the temperature of a metal increases, so does its electrical resistance. Platinum, copper and nickel have a predictable relationship between temperature and resistance. This means that as a current passes through a sensor containing one of these metals, a measurement of the resistance can determine the temperature value.
