DAC and SDAC Modules Figure 1 - Front View The optional DAC and SDAC modules are available for Watlow SERIES D8 controllers. DAC The DAC (digital to analog converter) converts one or two of the controller’s distributed zero crossing (DZC) output signals to analog signals. Each output is field configurable 50 mm for 4-20mAÎ(dc), 0-5VÎ(dc), or 0-10VÎ(dc). (2.0 in.) SDAC The SDAC (serial digital to analog converter) converts one controller output to a precise analog voltage or current signal. T
