The ACI A/GP 20'HARNESS is a 20 ft (6.10 m) Packard 3-pin wire harness for ACI GP Series and A/GP-N4 NEMA 4 gage pressure transducers. The A/GP 20'HARNESS uses plenum-rated jacketed cable, suitable for installation in air-handling spaces and return-air plenums per NEC Article 300.22(C), and terminates in a mating Packard 3-pin connector that plugs directly into the transducer.
Wire color coding follows the ACI GP wiring convention: Red is the power lead (to supply +), White is the return lead (to controller 4-20 mA analog input +), and a shield drain wire connects to earth ground. A black wire is included but is not used in 4-20 mA service.
Warranty
LIMITED
WARRANTY
Manufacturer-backed coverage. ACI accessories carry a Two (2) Year Limited Warranty. ZOT Supply is an authorized ACI distributor; the A/GP 20'HARNESS ships factory-new with full manufacturer warranty intact. Full terms appear in the front of ACI’s Sensors & Transmitters catalog and at workaci.com.
Key Features
Mating Packard 3-Pin Connector
Industry-standard Packard connector mates directly with the ACI GP / A/GP-N4 transducer body for a clean, vibration-resistant electrical connection. No additional adapters required.
20 ft (6.10 m) Plenum-Rated Cable
Pre-terminated 20 ft (6.10 m) cable in a plenum jacket. Plenum rated for use in air-handling spaces per NEC 300.22(C).
Color-Coded Conductors
Standard ACI color coding: Red (Power), White (Return / 4-20 mA signal), shield drain wire (earth ground). Black wire included but not used in 4-20 mA service.
Sized for Common Installations
Available lengths from 2 ft up to 40 ft (plenum) and 10 ft / 20 ft (metal-clad). Pick the length that matches the run from your transducer location back to the panel.

Frequently Asked Questions
What is the A/GP 20'HARNESS used for?
The A/GP 20'HARNESS is the cable harness that connects an ACI GP Series or A/GP-N4 NEMA 4 gage pressure transducer to your controller, PLC or data-acquisition system. ACI ships GP transducers with a Packard 3-pin connector only; the wire harness is sold separately so you can choose the length and cable type that matches your installation.
How long is the cable?
The A/GP 20'HARNESS is 20 ft (6.10 m) long, with a Packard 3-pin connector on the transducer end and tinned conductors on the controller end for direct wiring into a screw terminal.
Which transducers is the A/GP 20'HARNESS compatible with?
All ACI GP Series gage pressure transducers (model numbers beginning with GP(0-...) and ending in -P) and the NEMA 4 variants (A/GP(0-...)-20-P-N4). The Packard connector is standardized across the entire GP family.
How is it wired?
Connect Red to the plus terminal of the 13-30 VDC supply, White to the controller’s 4-20 mA analog input (+), Common (-) of the controller to the supply minus, and the shield drain wire to earth ground. The black wire is not used in 4-20 mA service.
Is the A/GP 20'HARNESS plenum rated?
Yes — the A/GP 20'HARNESS uses a plenum-rated jacket and is suitable for installation in air-handling spaces and return-air plenums per NEC Article 300.22(C).
