Key Features

• Sealed Design: Conformal coated PCB for harsh industrial environments

• Multi-Loop Control: Speed, current, voltage regulation for DC drives

• Front-Panel Interface: Gain, offset, threshold potentiometers; LED status indicators (Power, Run, Fault)

• Fault Diagnostics: Overcurrent, overtemperature, phase loss, short circuit detection

• Isolation: Galvanic isolation between I/O and logic ground (noise immunity)

Compatible Systems

• Series: SealPak DC drive systems (legacy, similar to CardPak)

• Matched Modules: 0-50005, 0-50010, 0-50015 (SealPak I/O & power cards)

• Application: Steel mills, paper mills, mining, heavy machinery DC drives

Installation & Calibration

Installation

1. De-energize the SealPak rack.

2. Insert 0-50001-2R into an empty slot; tighten front-panel locking screw.

3. Verify +5 VDC and ±15 VDC bus power.

Calibration

1. Power on; confirm Power LED is ON.

2. Apply reference signal; adjust Gain pot for target output.

3. Zero input; adjust Offset pot for 0 VDC output.

4. Set fault thresholds; adjust Threshold pot for alarm trigger points.

5. Lock potentiometers; test under load.

Operation & Faults

• Normal: Power/Run LEDs ON; stable output; no fault triggers.

• Fault LED ON: Overvoltage, short circuit, overheating, or interlock activation (reset after clearing fault).

• No Output: Check bus power, wiring, on-board fuse, or input signal.
