I. INTRODUCTION
Thank you for purchasing the SIVF Signal Isolator (P/N 9474). KB Electronics, Inc. is com-
mitted to providing total customer satisfaction by producing high quality products that have
been manufactured to the highest standards and techniques in the industry. The SIVF is
engineered with state-of-the-art surface mount technology (SMT) incorporating advanced
circuitry in a relatively small and user friendly package, making it convenient to operate and
easy to install.
The SIVF is used to isolate, amplify, and condition DC voltage and current signals from any
source (power supplies, motors, tachometer generators, transducers, and potentiometers).
The isolated output voltage of the SIVF provides input signals to all models of the KBVF
Adjustable Frequency Drive (P/N 9957, 9958, 9959, 9977, 9978, and 9979). Signal input
and motor direction control is performed by making connections to the on-board barrier ter-
minal. All inputs (+5V, SIG, COM, FWD & REV) to the SIVF are isolated from the AC line
and motor connections.
The SIVF is factory calibrated to accept signal input voltage (0 – 5V DC), current (4 – 20mA
DC), or a potentiometer (5K
Ω
) via a jumper selection. MIN and MAX trimpots are provided
in order to readjust the SIVF. This allows the use of 0 – 2.5 thru 25V DC input voltage sig-
nals for customizing specific applications.
