I. INTRODUCTION

Thank you for purchasing the SIMG Bipolar Signal Isolator (P/N 8832). KB

Electronics, Inc. is committed to providing total customer satisfaction by pro-

ducing quality products that are easy to install and operate. The SIMG is

manufactured with surface mount components incorporating advanced cir-

cuitry and technology.

The SIMG provides input isolation and is used to isolate, amplify, and condi-

tion DC voltage signals from any external source (power supplies, motors,

tachometer generators, transducers, and potentiometers). The isolated out-

put voltage of the SIMG provides input signals to the KBMG-212D (here-

inafter referred to as KBMG) Regenerative Drive (P/N 8831). In also pro-

vides isolation for motor direction switching and an isolated power supply for

transducer or potentiometer operation. The PWR LED provides indication

that power is applied.

All input connections (+15, -15, SIG, COM, and EN) are made via a barrier

terminal block and are isolated from AC line and motor wiring.

The SIMG is factory calibrated to accept a signal input voltage of -10V to

+10V DC. OFFSET and MAX trimpots are provided in order to recalibrate the

SIMG for specific applications.
