SES OUT2422 Model 2422 Industrial Analog Output Module

The OUT2422 (2422) is a rack‑mount analog output module for distributed process control systems. It receives digital commands from the main controller and converts digital data into standard 4‑20mA or 0‑10V analog signals to drive field actuators, valves and positioners.

This plug‑in module features channel isolation, output fault detection and short‑circuit protection. Original production has been discontinued. It serves as aftermarket spare parts for power, chemical and water treatment DCS cabinet overhaul and upgrade projects.
