Schneider Electric / Eurotherm Dimension 8725 PID Controller

The Schneider Electric Eurotherm Dimension 8725 is a modular multi-loop PID controller engineered for precision temperature and process control in industrial automation systems. This DIN-rail mounted instrument delivers up to 8 independent PID control loops with configurable control modes (PID, PI, PD, P, I) and auto-tuning functionality. The unit integrates 18 analog inputs, 12 analog outputs, 32 digital I/O points, and 8 programmers to support complex sequential and event-driven control strategies across demanding process applications.
