There is a second optional analog module available for the P632. In addition to the analog (I/O) module Y with analog inputs and outputs there is now a second analog module obtainable, the temperature p/c board (also called the RTD module).

When the P632 is equipped with the analog (I/O) module Y it has two analog inputs available for measured data input. Direct current is fed to the P632 through the 20 mA analog input (input channel 1). The other input is designed for connection of a PT 100 resistance thermometer.

The temperature p/c board (the RTD module) mounted in the P632 has 9 analog inputs available to connect temperature sensors T1 to T9. These analog inputs are designed for connection of PT 100, Ni 100 or Ni 120 resistance thermometers.

The input current IDC present at the analog (I/O) module Y is displayed as a measured operating value. The current that is conditioned for monitoring purposes (IDC,lin) is also displayed as a measured operating value. In addition, it is monitored by the Limit Value Monitoring function to detect whether it exceeds or falls below set thresholds (see “Limit Value Monitoring”).

The measured temperatures are also displayed as measured operating values and monitored by the Limit Value Monitoring function to determine whether they exceed or fall below set thresholds (see “Limit Value Monitoring”).

All measured variables are also forwarded to the Thermal Overload Protection function. With this protection it is possible to set whether the PT 100 resistance thermometer, the 20 mA analog input or – if configured – one of the temperature sensors T1 to T9 is to be used for the thermal replica (see “Thermal Overload Protection”).

The Measured Data Input function can be disabled or enabled via setting parameters.
