The SIMATIC DP, Electronic Module for ET 200 PRO 4 AO U High Feature (6ES7145-4FF00-0AB0) is a high-feature analog output module from Siemens, designed for SIMATIC ET 200 PRO systems, operating in voltage ranges of ±10 V, 0...10 V, and 1...5 V. The module provides 4 analog outputs (AO) and supports channel diagnostics. With a net weight of 0.181 kg and packaging dimensions of 7.40 x 13.70 x 6.60 cm, its compact design helps save space in control cabinets. The module includes a bus module, but the connection module (IO 6ES7194-4..00-0AA0) must be ordered separately. This module is used in SIMATIC ET 200 PRO systems for industrial automation projects, such as generating analog voltage signals to control actuators, regulators, or other devices, particularly in applications requiring high precision and diagnostics.
