GSDA-5K potentiometer kit
For use with all GSD series DC drives
The GSDA-5K is a replacement potentiometer kit that can be used with IronHorse GSD series DC drives to control the speed of a DC motor. (All GSD series DC drives include a speed potentiometer.) The kit includes:

Accel/Decel Adjustment Card
For use with all GSD4 DC drives
The GSDA-ACCDEC-4 option card overrides the fixed accel ramp built into the GSD4 drive, providing independently adjustable linear acceleration and deceleration from 0.5 to 8.0 seconds. Adjustments are made via two separate trim pots. This option card plugs into the expansion connector on the GSD4 main circuit board.

Analog Current Signal Input Card
For use with DC drives: GSD4-24x-xC (open-frame), GSD5-240-10C, GSD6 - all
The GSDA-AI-V4 option card is a 4-20 mA isolated analog current signal card that can replace the speed pot as a speed input signal to certain GSD series drives. The 4-20 mA signal input can be either grounded or ungrounded. The board sets on spacers screwed to the potentiometer HI, Wiper, and LO terminals on the main GSD drive board using screws (included).

Isolated Analog Voltage Signal Input Cards
GSDA-AI-V4:For use with GSD4-240-xxx (120-240V) DC drives
GSDA-AI-V5:For use with GSD5-240-10C (open-frame) DC drive
These option cards allow for the use of either a grounded or non-grounded remote DC signal such as 0-5 VDC through 0-250 VDC, 4-20mA current, or a remote speed pot. The DC input signal type can be selected for voltage (Vin) or current (4-20mA), and there is a GAIN trim pot to set full linear output in reference to the input signal range. The output of this remote signal isolation board is a linear signal that is proportional to the remote input signal being supplied.

Manual Reverse Switch
For use with DC drives: GSD3 - all, GSD4 - all, GSD5-240-10C (open-frame)
The GSDA-MREV Manual Reversing Switch is a 4PDT 10A-rated center blocked manual switch that can be used with certain IronHorse GSD series DC drives to manually reverse the direction of a DC motor. When switched between the Forward and Reverse positions, the blocked center position causes a delay which protects the DC drive from any voltage that may be on the motor armature terminals. The center position is OFF/NEUTRAL, and is not connected to a wiring terminal.
The GSDA-MREV manual reversing switch is $87.00GSD Series DC Drives Accessories Overview
For use with GSD4-xxx-xC (open-frame) DC drives
Optional heatsink for open-frame GSD4-xxx-1C and GSD4-xxx-5C DC drives only. Increases the output current capability of GSD4-240-5C drives to 10A (non-UL applications only).
The GSDA-HTSNK-4 heatsink
For use with DC drives:
GSD1 - all, GSD3-24A-xxx (12-24V), GSD4 - all, GSD5 - all, GSD6 - all, GSD7 - all
The GSDA-DP digital potentiometer is a compact, microprocessor-based unit capable of being either field or factory configured for a number of industrial user interface / control signal needs. The GSDA-DP allows the user to adjust the displayed value via the front-panel pushbuttons. The GSDA-DP provides an analog control voltage that can be used by most AC or DC drives as a steady, stable speed control signal. These units support both unipolar and bipolar output and are capable of automatically inverting, scaling, and offsetting the output as needed.
