Expansion and Accessory Boards
Baldor offers a wide variety of plug-in expansion boards to allow the Series 15H vector
controls to be interfaced with various inputs and outputs. One or two expansion boards may
be mounted into the control to custom tailor the inputs, outputs, and feedback requirements
to the application. Baldor also offers several expansion boards that will allow direct interfacing
with popular PLC’s.
Group 1 Boards
Isolated Input Board - EXB003A04 (10-30 Volts)
Isolated Input Board - EXB003A05 (90-130 Volts)
This board replaces the opto inputs on the main control board with isolated inputs. All inputs
must be in the same voltage range and one side of all inputs is common. Screw terminals are
provided for easy connection.
Master Pulse Reference/Pulse Follower - EXB005A01
This board is jumper selectable to create a master pulse reference based on the controls
speed/direction command or selected as an isolated pulse follower. The follower can be
ratioed up or down to the master pulse through the control keypad. The master or follower
pulse train can also be configured as a two channel quadrature pulse with complements or
configured as a one channel pulse train for speed and one channel for direction. As a follower,
the pulse train will be retransmitted to the next follower as received from the master.
DC Tach Interface - EXB006A01
Allows a DC Tachometer to be used as a feedback or command signal to the controls built-in PID Set Point Controller. Jumper selectable for 7,
10, 15, 20, 30, 50, 60, 100, 200, 250 VDC per 1000 RPM tachometers with a software trim for 10% tolerance. Screw terminals are provide for
easy connection.
Group 2 Boards
RS232/RS485 Serial Communication - EXB012A01
Allows serial communication for commands and monitoring. 115.2K baud maximum transmission rate. Screw terminals are provided for easy
connection.
Four Output Relay/3-15 PSI Pneumatic Interface - EXB004A01
Converts 3-15 PSI air pressure to 0-10 VDC or 10-0 VDC (inverted) to be used as a command or feedback signal. Also includes four output
relays to replace the four opto outputs on the main control board. Two relays are jumper selectable for N.O. or N.C., rated for 230 VAC , 5 Amps
max and two form “C” relays (N.O. and N.C.). Please note that relay outputs are dry contacts with no power supplied from the control. Screw
terminals are provided for relay connections and air hose connects to 1/8" O.D. nipple on expansion board.
High Resolution Analog Board - EXB007A02
Contains one high resolution input channel to replace Analog Input #2 on the main control board. The resolution will be as follows: ±10 VDC = 16
bit, 0-10 VDC = 15 bit, ±5 VDC = 15 bit, 0-5 VDC = 14 bit, 4-20 mA = 15 bit. Also contains two high resolution analog outputs to replace Analog
Output #1 and #2 on the main control board. The outputs are selectable for ±10 VDC, 0-10 VDC, and 4-20 mA with inverting capability. Requires
100 second warm up period for full 16 bit resolution. 12 bit minnimum. Screw terminals are provided for easy connection.
Two Analog Output/ Three Relay Output Board - EXB010A01
Provides two isolated analog outputs each with 0-5 VDC, 0-10 VDC, or 4-20 mA capability. Also includes three relay outputs jumper selectable
for N.O. or N.C. rated for 230 VAC, 5 amps maximum. Uses screw terminals for connection.
DeviceNet Communication Board - EXB013A01
Allows connection to DeviceNet communications bus. Uses plug in terminals for connection.
Profibus DP Communication Board - EXB014A01
Allows connection to Profibus DP communications bus. Uses plug in terminals for connection.
Modbus Plus Communication Board - EXB015A01
Allows connection to Modbus Plus communications bus. Uses plug in terminals for connection.
Group 1 and Group 2 Ordering/Mounting Information
• NOTE: Expansion boards plug into the main control board inside the control. When using one expansion board, either a Group 1 or Group 2
board will connect to the main control board. When two expansions boards are used, one must be from Group 1 and one from Group 2. The
Group 1 board will connect to the main control board and the Group 2 board will connect to a stacking connector on the Group 1 board.
Accessory Boards
Isolated Input/2 Relay Output Accessory Board - ACB003A01
Contains 9 isolated inputs for 90-130 VAC. Also has 2 Relay outputs, Form C: N.O. and N.C. Accessory board mounts in expansion board slot
but uses wiring harness to connect to motor control card.
