Product Description

6ES7231-5QF32-0XB0 SIMATIC S7-1200 SM 1231 TC Analog input modules PLC

SIMATIC S7-1200, Analog input, SM 1231 TC, 8 AI thermocouples

Overview

• For the convenient recording of temperatures with great accuracy
• 7 common thermocouple types can be used
• Also for the measurement of analog signals with a low level (±80 mV)
• Can easily be retrofitted to existing plant

 

 

Application

The SM 1231 thermocouple modules enable temperatures to be measured with high precision using established thermocouples. In addition, low level analog signals in the ±80 mV range can be recorded. The SM 1231 thermocouple modules can be used with the CPUs of the S7-1200 series.

 

 

Design

The SM 1231 thermocouple modules exhibit the same structural features as the other modules of the S7-1200 series:

• Mounting on a DIN rail:
  The modules are snapped onto the rail just to the right of the CPU and connected to one another and with the CPU 12xx by means of the integral backplane bus.
• Direct mounting:
  Drilled holes permit the module to be bolted directly to walls. This type of mounting is recommended for applications subject to strong vibrations.
• Thermocouples:
  Four thermocouples each of types J, K, T, E, R, S and N can be used. They are connected directly to the module without amplifiers.
• Mounting location:
  For maximum possible measurement and repeat accuracy, the thermocouple modules should be mounted in locations with low temperature variations.

 

 

Function

Different measurement ranges:
Thermocouples of types J, K, T, E, R, S and N; analog signal recording ±80 mV.

Check for open lines.

Compensation of the cold connecting point:
Faults caused by contact voltages at the connection between thermocouple and module are prevented; when recording analog signals (±80 mV), the compensation is automatically deactivated.

Temperature scaling:
The measured temperature can be shown in °C or °F.
