Siemens 6ES7135-6HB00-0CA1 SIMATIC ET 200SP AQ 2xU/I HF 16-Bit Analog Output Module

The Siemens 6ES7135-6HB00-0CA1 is a SIMATIC ET 200SP analog output module (AQ 2xU/I HF) with 2 channels, each configurable for voltage (0-10 V, +/-10 V, 1-5 V, +/-5 V) or current (0-20 mA, 4-20 mA, +/-20 mA) output at up to 16-bit resolution. It supports isochronous mode at a 250 microsecond execution time.

Technical Specifications

Selection Notes

Both channels support voltage and current output on the same module, so one part number covers 0-10 V positioning references and 4-20 mA valve or actuator commands without stocking separate voltage-only and current-only variants. Isochronous mode with a 250 microsecond execution time matters for motion or closed-loop control synchronized to the PROFINET IRT cycle; a simple setpoint output without hard real-time timing doesn't need that configuration. The 1,000 m shielded cable length on current output versus 200 m on voltage output should drive the channel-type choice on long runs to field actuators, and the fixed 750 microsecond minimum cycle time across both channels caps the fastest possible update rate.

Applications

Analog setpoint output to VFDs and valve positioners, proportional valve control, and closed-loop process control loops on ET 200SP distributed I/O stations.
