WATLOW SDAC User’s Guide 1

Introduction

The Serial Digital-to-Analog Converter (Serial DAC) is

an optional module for Watlow Anafaze Controllers. It

allows the controller to output precision analog volt-

ages or currents. The Serial DAC is typically used for

precision open-loop control, motor or belt speed con-

trol, or phase-angle fired control.

This manual contains installation instructions, config-

uration information, and specifications.

Features

• Electrically isolated

• 0.003% resolution and linearity; factory calibrated

to 0.05% accuracy for voltage outputs and 0.5%

accuracy for current outputs. The Serial DAC can

also be recalibrated to 0.1% accuracy on current

output.

• User-selectable voltage or current output.

• Controller setup menus allow zero- and full-scale

value adjustments within the Serial DAC’s 0 to

10V

Î (dc) and 0 to 20 mAÎ (dc) output ranges.

Installing the Serial DAC

You will need the following tools:

• Power drill with 4-mm (0.15-in) bits

• Screwdriver

• Four screws up to size #6 (up to 3.8 mm). Choose

screws appropriate for your panel material.

• Wire strippers

SDAC User’s Guide

To install the SDAC module:

1. Choose a wall or panel to install the Serial DAC.

For best results choose a location near the con-

troller and in an area free from dust, excessive

heat and moisture and unauthorized personnel.

2. Drill four holes for screw mounting. See Figure 1

on page 2 for mounting hole dimensions and place-

ment.

3. Place the Serial DAC in its mounting location so

that the screw holes in the Serial DAC line up

with the holes you have drilled. Insert the screws

in the holes and tighten.

4. Shut the system power off and wire the Serial

DAC to the controller and final control element.

Warranty

The Serial DAC is warranted to be free of defects in

material and workmanship for 36 months after deliv-

ery to the first purchaser for use, providing that the

units have not been misapplied. Since Watlow has no

control over their use, and sometimes misuse, we can-

not guarantee against failure. Watlow’s obligations

hereunder, at Watlow’s option, are limited to replace-

ment, repair, or refund of purchase price, and parts

which upon examination prove to be defective within

the warranty period specified. This warranty does not

apply to damage resulting from transportation, alter-

ation, misuse, abuse, or improper fusing.
