DDM-880 Dimming Module
DDM - 880 Dimming Module Lighting Control for Automation
Delta Controls’ DDM-880 dimming module are specifically designed for Daylighting applications using dimmable ballasts. These dimming modules connect to Delta’s BACnet™ Controllers over Delta’s LINKnet network.
Each of the device’s eight outputs is capable of controlling up to fifty 1-10V dimming ballasts. Each output has an associated photocell input with a calibration potentiometer to adjust sensitivity of the input which the controller uses in a built-in Proportional-Integral (PI) loop to smoothly adjust the lighting levels to the desired setpoint.
The DDM-880 provides up to eight channels of simple distributed daylighting control per module reducing field wiring by being able to locate the module close to the zones being controlled.
