Product Description

6ES7231-5QA30-0XB0 S7-1200 Analog input modules SB 1231 thermocouple signal board

SIMATIC S7-1200, Analog input, SB 1231 TC, 1 AI thermocouples Type J or K

 

Overview

• For the convenient recording of temperatures with great accuracy
• 1 input with 16-bit resolution
• 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
• Can be plugged directly into the CPU

 

Application

The SB 1231 thermocouple signal board permits temperature recording with high precision using established thermocouples. In addition, low level analog signals in the ±80 mV range can be recorded. The SB 1231 thermocouple signal board can be plugged directly into all SIMATIC S7-1200 CPUs.

This provides users with the following advantages:

• Optimal adaptation:
  With signal boards, users can optimally adapt their controllers even to more complex tasks.
• Flexibility:
  If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple.
• Use where space is limited:
  The signal boards are directly plugged into the CPU, enabling the controller to be expanded without taking up any additional space.

 

Design

The signal boards are plugged straight into the holder on the front of the S7-1200-CPU.

• Installation:
  Signal boards are plugged directly into the SIMATIC S7-1200-CPU and are thus connected electrically and mechanically with the CPU.
• The installation dimensions of the CPU remain unchanged.
• Replacement of all signal boards is facilitated by removable terminals ("permanent wiring").

 

Function

• Different measuring ranges:
  Type J and K thermocouples; analog signal recording ±80 mV.
• 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 scale:
  The measured temperature can be displayed in °C or °F.
