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 for
SDAC
The SDAC (serial digital to analog converter) converts one controller output to a precise analog voltage or current signal. The unit is typically used for process variable retransmit,
or
Because the SERIES D8 has no onboard analog outputs, applications that use process variable retransmit typically require one SDAC module per retransmitted signal.
