Siemens 6DR2801-8E Signal Transmitter

Siemens 6DR2801-8E Signal Transmitter is a SIPART DR signal converter that expands the digital I/O of SIPART DR controllers by providing four binary outputs (BA) and two binary inputs (BE) operating at 24 V DC. Built for use with the SIPART DR21/DR22 family, this module interfaces directly with control logic and field devices to implement straightforward on/off signaling in industrial automation systems. The 6DR2801-8E is configured as 4BA/2BE, which translates to four digital outputs and two digital inputs, allowing compact, modular expansion of digital channels without modifying the central controller. Signaling is based on standard 24 V logic typical in factory environments, making it suitable for tasks such as drive starts/stops, interconnections with limit switches, and basic condition monitoring within Siemens SIPART DR installations. As an expansion module for SIPART DR hardware, it simplifies wiring and integration, helping engineers scale digital I/O in constrained spaces while preserving the integrity of the existing Siemens control architecture. This model is one of Siemens’ SIPART DR signal modules designed to complement DR-series controllers with binary I/O capability.
