SIAC-PS
D-820
KB Part No. 9600C
Signal Isolator with Power Supply For all KBAC (2G) Series Inverters Signal Isolator
Provides isolation between non-isolated signal sources and the drive.
Isolated 5V Power Supply For potentiometer operation.
SIAC-PS (Part No. 9600C)
Isolated 24V Power Supply*
To power transducers or auxiliary equipment.
Description
Standard Features
Isolated Switching: Provides isolation for PLC open collector or contact switching. Trimpot Adjustments (Multi-Turn): Maximum Speed (MAX1) and Signal Offset (OFFSET). Power On LED: Provides indication that power is applied. Signal Input Selection (Jumper J1): Selects voltage or current signal inputs. Easy Installation: A snap-in Mounting Base and Interconnecting Ribbon Cable are provided for easy installation into the drive. Optional Accessory: Auto/Manual Switch (Part No. 9481) selects a signal input from either the SIAC-PS or the Main Speed Potentiometer.

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 (Part No. 9481) to select a signal input from either the SIAC-PS or the Main Speed Potentiometer of the drive.

The SIAC-PS Signal Isolator with Power Supply provides an isolated interface between non-isolated signal sources and the drive. It is used with the KBAC 2G Series Drives 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.
