Siemens 6ES7452-1AH00-0AE0 Analog Output Module

Product Description

The Siemens 6ES7452-1AH00-0AE0 is an 8-channel analog output module developed for the SIMATIC S7-400 platform, enabling accurate generation of analog control signals for industrial processes. It is intended for applications where stable and precise output values are required to regulate field devices such as control valves, variable speed drives, and positioning systems.

This module supports both voltage and current outputs, including ±10 V and 0/4–20 mA ranges, offering flexibility for different control strategies. With 12-bit resolution and fast channel conversion, the 6ES7452-1AH00-0AE0 ensures consistent signal quality across all outputs.

Electrical isolation between channels and the backplane bus enhances system protection, while onboard LED indicators provide clear status feedback for each channel. Designed for integration into S7-400 racks, it delivers reliable performance in demanding automation environments.
