Siemens 6ES7135-6TD00-0CA1 Analog Output Module

Siemens SIMATIC ET 200SP analog HART output module AQ 4xI HART HF, article number 6ES7135-6TD00-0CA1, delivers four current-output channels for precise actuation of field devices in ET 200SP installations. As a High Feature module, it includes HART communication on its outputs, enabling device diagnostics and two-way data exchange with HART-enabled instruments. The module is intended for BU type A0/A1 backplanes (color code CC00) and supports per-channel diagnostics. It features 16-bit resolution across its four outputs, with typical accuracy around ±0.3% of span. Output ranges supported are 0–20 mA, 4–20 mA, and 4–20 mA HART on each channel. The unit is powered from a 24 V DC supply, common for ET 200SP modules, and integrates seamlessly into Siemens ET 200SP systems for direct drive of actuators or valve control, with HART enabling configuration and status readback from connected field devices.
