Watlow SERIES CLS200 DAC and SDAC Modules

DAC and SDAC Modules

The optional DAC and SDAC modules are available for Watlow SERIES CLS200 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 4-20mA(dc), 0-5VDC or 0-10VDC.

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, open-loop control, motor or belt speed control, or phase-angle

fired SCR power controllers. The SDAC bears the CE mark and is UL® and C-UL® listed.

Firmware Options

Choose firmware with the features needed for the application:

• Standard—includes closed-loop PID control, auto-tune, alarms, job memory

and failed sensor detection.

• Ramp and soak—includes the standard firmware features with the addition

of ramp and soak and process variable retransmit. Each channel can be

configured for standard PID control or ramp and soak operation.

Unused control outputs on any channel can be configured for retransmition.

• Enhanced features— includes the standard firmware features with the addition

of process variable retransmit, remote analog set point, cascade control, ratio control

and differential control algorithms. Each channel can be configured for standard

PID controller or one of the other control algorithms. Each channel of cascade

control or remote analog set point requires two controller channels.

Unused control outputs on any channel can be configured for retransmit.

Because the SERIES CLS200 has no onboard analog outputs, applications that use

process variable retransmit typically require one SDAC module per retransmitted signal.
