Product Introduction & Supply Chain Strategy
The API4380GD by Absolute Process Instruments is an industrial-grade plug-in signal conditioner engineered to isolate, convert, and boost DC voltage or current signals in process automation systems. Featuring 3-way optical isolation up to 1200 V RMS, the API4380GD safely breaks common ground loops, protects sensitive PLC/DCS input cards from voltage spikes, and cleans up noisy field transmitter signals.
Sourcing the API4380GD as New Surplus provides plant instrumentation technicians and automation integrators with a fast, reliable supply chain solution. In process monitoring and data acquisition loops, a failed signal conditioner can disrupt accurate sensor readings or trip downstream controllers. Keeping unused surplus API4380GD modules on hand ensures immediate drop-in replacement without modifying panel wiring, lowering overall operational downtime and Total Cost of Ownership (TCO).

Installation & Configuration Guide
1
Pre-Installation & Power Isolation
Disconnect line voltage and verify socket wiring
1.Pre-Installation & Power Isolation:Disconnect line voltage and verify socket wiring.
- Turn off and lock out power to the 11-pin octal socket base before inserting or configuring the module.
- Check the socket pinout against API engineering schematics to ensure correct power, input, and output wire locations.
- Verify that field signal polarity (positive/negative) matches the module pin allocations.

DIP Switch Selection & Range Setup
2.DIP Switch Selection & Range Setup:
- Locate the range setting DIP switches on the side of the API4380GD housing.
- Set the input and output DIP switches to match your desired process signal ranges (e.g., 4–20 mA input to 0–10 V DC output).
- Ensure all switch toggles are fully seated in their designated ON or OFF positions.
3
Module Insertion & Mechanical Locking
3.Module Insertion & Mechanical Locking:
- Align the center alignment key of the 11-pin connector plug with the socket base notch.
- Press the module firmly into the socket until the unit seats flush against the base.
- Secure the spring retaining clip over the top of the module if installed in high-vibration enclosures.
4
Power Application & Calibration Fine-Tuning
4.Power Application & Calibration Fine-Tuning:
- Apply power to the socket base and confirm that the power LED illuminates.
- Apply a known minimum input signal (e.g., 4 mA) and adjust the front-panel ZERO potentiometer for exact zero output calibration.
- Apply a maximum input signal (e.g., 20 mA) and adjust the front-panel SPAN potentiometer to complete 2-point loop calibration.
Firmware/Software Versions & Upgrade Notes
- Hardware DIP Switch Configuration: The requires no programming software or PC connection cables. All signal ranges, span adjustments, and operational modes are set via physical DIP switches and front-panel potentiometers.
- Socket Interchangeability: Designed for standard 11-pin Octal bases (e.g., API011 or API011K socket bases), allowing tool-less module swapping during maintenance routines.
- Hot-Swappable Design: The octal plug-in architecture allows rapid removal and replacement; however, power to the socket base should be isolated prior to swapping to prevent arcing on socket contacts.
Frequently Asked Questions (FAQ)
Is this module authentic OEM and completely unused?
Yes. This unit is New Surplus (Original New). It is an authentic Absolute Process Instruments (API) module sourced from canceled integration projects or strategic maintenance reserves. It has never been installed in an active process panel.
Why choose New Surplus over a refurbished signal conditioner?
Refurbished process transmitters often suffer from aged electrolytic capacitors and drifted potentiometer calibrations caused by long-term exposure to panel heat. In high-accuracy monitoring applications, signal drift leads to false process readings and control errors. New Surplus guarantees factory-fresh component stability and 100% calibration precision out of the box.
What is the advantage of 3-way isolation on the ?
3-way isolation completely galvanically separates the input signal, output signal, and power supply from each other. This prevents high-voltage transients on field wiring from reaching the power supply or damage to PLC input cards, while eliminating ground loops caused by differing earth potentials.
Can the convert a 4–20 mA current loop into a 0–10 V DC signal?
Yes. The field-selectable DIP switches allow a wide variety of input-to-output conversions, including 4–20 mA to 0–10 V DC, 0–5 V DC to 4–20 mA, and 1-to-1 signal isolation loops.
What warranty is included with this product?
We back this unit with a 1-Year Comprehensive Replacement Warranty. Every module undergoes physical inspection and signal calibration testing prior to shipment.
