ABB SPAS011 Symphony Plus Analog Output Module

Description

The SPAS011 delivers the critical interface for industrial modulating control. It converts digital data to proportional analog signals (4-20mA/1-5V DC) to manage actuators, positioners and variable speed drives. High-resolution, galvanically isolated output channels ensure stable, accurate control—with robust signal integrity against EMI, ideal for power plants, water treatment and petrochemical refineries.
