Isolator/Converter with Display
Introduction
This is the users’ manual for Moore Industries’
SDY PC-Programmable Signal Isolator/Converter.
It contains all of the information that is needed
to configure, install, operate, maintain, and
troubleshoot the SDY. If you require additional
assistance, call one of our STAR Centers (for
Service, Technical Assistance, and Repair) to talk
with a technician or engineer.
The following guidelines are used in this manual:
WARNING - Hazardous procedure or condition that
could injure the operator.
Caution - Hazardous procedure or condition that
could damage or destroy the unit.
Note
- Information that is helpful for a procedure,
condition, or operation of the unit.
The SDY
The SDY is a versatile, 2-wire (loop-powered),
PC-Programmable Signal Isolator/Converter that
accepts current or voltage input and provides an
isolated, proportional 4-20mA output. See Figure 1
for a list of accommodated input types.
Typical uses for the SDY include:
• Isolating Signals to stop erratic process
measurements caused by ground loops
• Converting Signals so field instruments can
interface directly with indicators, recorders,
DCS’s, PLC’s, and PC-based SCADA systems
• Diverting Signals so the output from one
transmitter can be sent to two separate locations
• Protecting Equipment and Signals by eliminating
common electrical paths
• Boosting Signals to enable more instruments to
be added to an overburdened loop
• Solving the “Bucking Power Supplies” problem
that occurs when a 4-wire transmitter and a
DCS both try to power the same process loop
Figure 1.
Compact, yet powerful, the SDY transmitter features programmable inputs and a trimmable output to boost accuracy.
