Core Specifications of the Proportioning Module

The 6ES5261-4UA11 belongs to the Siemens SIMATIC S5 family of proportioning modules. This intelligent card controls closed-loop positioning tasks in legacy automation racks. Moreover, it handles valve and actuator commands without burdening the main CPU.

Each module occupies a single slot in the S5 central rack. Additionally, the unit weighs roughly 0.50 kg with its front connector installed. The front panel measures 20 mm in width and 130 mm in height, while the 4UA11 suffix defines the channel count and control algorithm.

Interface and Mounting Details

The 6ES5261-4UA11 slides into the S5 rack and connects to the backplane bus. Consequently, technicians complete replacement without rewiring field terminations. This module drives actuators through a front screw terminal strip. Therefore, it simplifies wiring for analog control loops.

The analog output delivers a ±10 V DC signal with 12-bit resolution. Meanwhile, the compact housing fits standard S5 rack clearances.

Performance and Application Notes

Plant engineers deploy the 6ES5261-4UA11 for precise valve and damper positioning. Furthermore, the module executes closed-loop control independently of the main CPU. Its 12-bit resolution enables fine actuator adjustments across the full stroke. Meanwhile, the backplane interface keeps setpoint data synchronized with the controller.

The module stores no energy internally, since it draws power from the backplane. As a result, it adds minimal load to the S5 power budget.
