SIMATIC S7-1200, Analog output module 6ES7232-4HD32-0XB0

SIMATIC S7-1200, Analog input, SM 1231, 4 AI, +/-10 V, +/-5 V, +/-2.5 V, or 0-20 mA/4-20 mA, 12 bit+sign (13 bit ADC)

Using the analogue input module SM 1231 AI - 6ES7231-4HD32-0XB0 from Siemens your SIMATIC S7-1200 controller can be expanded by 4 analogue inputs. The analogue input SM 1231 AI - 6ES7231-4HD32-0XB0 processes signals with +/- 10 V, +/- 5 V, +/- 2.5 V or 0 (4) to 20 mA, at a resolution of 12 bits + sign bit (13 bits ADC).

The SM 1231 analog input signal modules allow the connection of the controller to analog signals of the process.

This provides users with the following advantages:

With analog signal modules, users can optimally adapt their controllers even to more complex tasks

Up to 14 bit resolution and different input ranges permit the connection of sensors without additional amplifier

If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple

The signal modules have the same design features as the basic devices.

The modules are snapped onto the rail next to the CPU on the right and are electrically and mechanically connected to each other and to the CPU by the integral slide mechanism.
Horizontal or vertical mounting on DIN rail or direct mounting in the cabinet using integral lugs.

The SM 1231 analog input signal modules convert analog signals from the process into digital signals for internal processing by the SIMATIC S7-1200 controller.
