APPENDIX A – Optional SIAC-PS Signal Isolator with Power Supply
See SIAC-PS Installation Instructions for details and connections.
Description
The SIAC-PS Signal Isolator with Power Supply provides an isolated interface between non-isolated signal sources
and the drive. It is used to isolate, amplify, and condition DC voltage and current signals from any source
(tach-generators, transducers, PLCs, and potentiometers). It provides an isolated input to control motor direction
and an isolated 5 Volt DC power supply for potentiometer operation. In addition, this updated model contains an
isolated 24 Volt DC power supply for transducers or auxiliary equipment. All input connections and power supplies
are isolated from the AC Line and motor wiring. It installs easily into the drive with a snap-in mounting base and is
wired with a connector.
Main features include voltage or current signal inputs. Other features include a power on LED, barrier terminal blocks
to facilitate wiring, multi-turn trimpots (MAX1, OFFSET), and a jumper for voltage or current signal input selection.
An optional accessory for use with the SIAC-PS is the Auto/Manual Switch to select a signal input from either the
SIAC-PS or the Main Speed Potentiometer of the drive.
