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.


Order the controller and desired options with the following product numbers: DDM-880 –Delta Dimming Module with (8) Photocell Inputs, (8) 1-10V outputs.
