2 INTRODUCTION
Thank you for purchasing the IODA Input/Output Multi-Function Board.
KB Electronics, Inc. is committed to providing total customer satisfaction by producing
quality products that are easy to install and operate.
The IODA Input/Output Multi-Function Board provides a variety of functions which
include preset frequency, up/down frequency control, signal isolation, isolated output
voltage for controlling auxiliary devices, output relay contacts, and open collector
outputs. The IODA mounts on the drive's PC board with 2 snap-ins (located on the
bottom of the mounting base) and 2 screws (provided). All of the IODA inputs and
outputs are isolated from the AC line.
The IODA has a green power on LED (PWR) and a red status LED (STATUS), which
are used to provide operational information of the IODA. See Table 27, on page 43,
for a description of the status LED. See Figure 1, on page 6, for the IODA layout. See
Figure 10, on page 13, for Terminal Block TB1 Layout. See Table 1, on page 14, for
Terminal Block TB1 Wire and Tightening Torque Specifications. See Table 2, on page
14, for the Functions, Features, and Terminal Assignment. See Sections 4.1 – 4.6, on
pages 15 – 26, describing the use of the IODA Multi-Function Input Terminals for
remote operations. See Sections 4.7 – 4.11, on pages 26 – 39, for other functions and
features of the IODA.
STANDARD FEATURES
▪ Signal Input Isolation: Provides isolation between signal sources and the drive.
▪ Potentiometer Operation: A 5 kΩ potentiometer can be used to in lieu of the
Keypad or the Built-In Potentiometer. The Main Speed Potentiometer can be
connected for forward, reverse, or bidirectional motor speed control.
▪ Multi-Function Input Terminals: Used for a variety of functions, which include
Preset Frequency; Up/Down Frequency Command; Forward/Stop and Reverse/Stop
Command; External Fault; Reset; 2-Wire and 3-Wire Start/Stop.
▪ Multi-Function Output Relays: Two Multi-Function Output Relays are provided,
which can be programmed for Run, Fault, Target Frequency, Frequency Threshold
Level, I
2 t or I•t Fault, Load Loss, External Fault, and Motor Overload.
▪ Multi-Function Open Collector Outputs: Two Multi-Function Output Relays are
provided, which can be programmed for Run, Fault, Target Frequency, Frequency
Threshold Level, I
2 t or I•t Fault, Load Loss, External Fault, and Motor Overload.
▪ Isolated Signal Output: Two isolated analog signal outputs are provided, which can
be used to monitor Motor Frequency, set Frequency, Motor Voltage Bus Voltage,
and Motor Current. Analog Output 1 provides a 0 – 5 Volt DC signal output. Analog
Output 2 can be programmed for 0 – 5 Volt DC, 4 – 20 mA DC, or for 0 – 20 mA DC.
▪ Selectable Jumpers: For voltage or current signal selection.
▪ Multi-Turn Trimpots: For fine adjustment and attenuation of signal inputs.
▪ LEDs: The green power on LED (PWR) indicates that power is applied to the IODA
from the drive. The red status LED (STATUS) provides indication of the IODA
operation.
▪ Barrier Terminal: All connections to the IODA are made via the barrier terminal
block. All terminal block connections of the IODA are isolated from the AC line.
▪ Easy Installation: Uses a snap-in base and two screws (provided) for mounting and
a ribbon cable for wiring to the drive.
