Replacement Potentiometer Kit
The GSDA-5K is a replacement potentiometer kit that can be used with all 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:
- (1) 5k ohm potentiometer
- (3) pigtail wiring leads (8-1/2 in; 20 AWG)
- (1) adjustment knob
- (1) 0-100% dial
- (1) mounting nut and lock washer

(GSDA-5K)
Independent Accel/Decel Adjustment Card
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.

$27.00
(GSDA-ACCDEC-4)
Isolated Analog Current Signal Input Card
The GSDA-AI-A option card is a 4-20 mA isolated analog current signal card that can replace the speed pot as a speed input signal to select 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).

$64.00
(GSDA-AI-A)
Isolated Analog Current/Voltage Signal Input Cards
These option cards are used with select DC drives and 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.

(GSDA-AI-V5)
Manual Reverse Switch
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.

Heatsinks
Optional heatsinks for select GSD4 and GSD4A drives only. Increases the output current capability of the associated drives.

(GSDA-HTSNK-4A)
Digital Potentiometer
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.
- 1/8 DIN durable aluminum housing for panel mounting
- Large 4-digit, 1/2" LED display
- Meets NEMA 4X standards when used with NEMA 4X enclosures
- Universal power supply accepts line voltage inputs from 85-265 VAC @ 50-60Hz
Starting at
$412.00
(GSDA-DP)
PID Controller
The GSDA-DP-D motor speed controller is a compact, microprocessor-based unit capable of being either field or factory configured for a number of motion control needs. The control is designed around a velocity form PID algorithm and provides a DC speed pot signal to an external drive.
Starting at
$464.00
(GSDA-DP-D)
Signal Conditioner
The GSDA-DP-S is a panel mounted, multi-purpose signal conditioner that allows the operator easy access to make adjustments to system operations. Featuring a dual-mode operation (signal scaling or signal generation) and transient voltage protection, these modules are ideal for drives that require frequent adjustments to meet application needs.
Starting at
$391.00
(GSDA-DP-S)
Relay/Analog Combo Module
For use with select GSD8 drives, this option card features an optically-isolated 4-20 mA current loop input and an optically-isolated 4-20 mA current loop output. In addition, a non-isolated SPST switch input is provided.
Starting at
$195.00
(GSDA-AI-A8)
Communication Module
For use with select GSD8 drives, this ASCII option card has RS-232 or RS-485 serial communications with a configurable 300 to 57.6K baud rate.
Priced at
$142.00
(GSDA-CM-8)
Encoders
For use with all GSD8 drives and the GSDA-DP-D PID controller, these encoders provide one pulse per revolution, operating from a +5V power supply and producing a 5V square wave whose frequency is proportional to speed. The PU2E is designed for indoor use, while the PU2R is for washdown or outdoor use.
