PRODUCT DESCRIPTION

6ES7231-7PB22-0XA8 EM 231 two-channel RTD input module

Siemens 6ES7231-7PB22-0XA8 is an EM 231 analog input expansion module for SIMATIC S7-200 controllers. It is designed for temperature and resistance measurement through two sensor channels. The manufacturer data further identifies the system family as SIMATIC S7-200, the module designation as EM 231, the module type as RTD/resistance analog input, the analog inputs as 2, the supported measurement as Temperature and resistance, the sensor families as Pt, Ni and Cu, and the input signal as RTD and resistance.

The two inputs support RTD and resistance signals from documented Pt, Ni and Cu sensor ranges. Signal conversion uses 15-bit resolution plus sign and the module operates from a 24 V DC supply. The remaining technical data identifies the resolution as 15 bit plus sign, the supply voltage as 24 V DC, the signal direction as Field to controller, the controller interface as S7-200 expansion bus, the channel function as Two sensor measurements, the conversion type as Analog-to-digital, the station role as Analog input expansion, and the application class as Temperature acquisition.

SYSTEM INTEGRATION

Integrate 6ES7231-7PB22-0XA8 EM 231 two-channel RTD input module

Use 6ES7231-7PB22-0XA8 within the documented SIMATIC S7-200 automation architecture and assign it to the hardware position intended for its EM 231 two-channel RTD input module function. The controller project and physical station should use the same module identity and system structure.
Coordinate the rack or distributed I/O position with the controller address map, process image and diagnostic handling. Field wiring should follow the manufacturer terminal conventions, with signal references, grounding and shielding arranged consistently with the surrounding modules.
Complete the hardware configuration in the engineering project and review the station diagnostics before enabling the affected process functions. Retain the final module assignment, connection records and controller configuration as part of the system documentation.

Features:

  • Exact model: 6ES7231-7PB22-0XA8
  • Compatible system: SIMATIC S7-200
  • Intended role: EM 231 two-channel RTD input module
6ES7231-7PB22-0XA8 should be integrated within the documented SIMATIC S7-200 system architecture and retained in the approved project records.
INTERCHANGEABILITY

Check 6ES7231-7PB22-0XA8 technical compatibility

Use the complete 6ES7231-7PB22-0XA8 order identity when evaluating interchangeability within the SIMATIC S7-200 system. Similar appearance or a shared family name does not establish compatibility with the installed hardware and engineering project.
Record the installed position, connector orientation, field wiring, address assignment, communication settings and application configuration before removing the existing unit. Preserve cable labels, shielding arrangements and diagnostic records needed to reproduce the documented system state.
After fitting the selected unit, restore the approved configuration and review controller or device diagnostics before enabling the affected function. Confirm the connected signals and controlled response through the established commissioning procedure, then update the maintenance record.

Features:

  • Complete identity: 6ES7231-7PB22-0XA8
  • System compatibility: SIMATIC S7-200
  • Configuration and connection records retained
Interchangeability for 6ES7231-7PB22-0XA8 depends on the complete order identity and the documented electrical, signal and platform characteristics.
