SIAC-PS KB Electronics 3G KBAC Signal Isolator Board 8890

KB SIAC-PS 3G Signal Isolator with Power Supply (hereinafter referred to as "Signal Isolator") provides an isolated interface between nonisolated signal sources and the drive. It is used with the KBAC 3G 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, an isolated 5 Volt DC power supply for potentiometer operation, and an isolated 24 Volt DC power supply to power 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 snapin mounting base and is wired with a connector.

Main features include voltage or current signal inputs. Other features include power on (PWR) and status indicator (IND) LEDs, barrier terminal blocks to facilitate wiring, multi-turn trimpots (SCALE, OFFSET), a jumper for voltage or current signal input selection (VOLT, CUR), and a jumper for signal input type selection (PWM, AN). An optional accessory, for use with the Signal Isolator, is the Auto/Manual Switch (Part No. 8891), which selects a signal input from either the Signal Isolator or the Main Speed Potentiometer of the drive.
