05701-A-0329 by Honeywell 3-Channel DPCO Relay Card Module
05701-A-0329 by Honeywell | 3-Channel DPCO Relay Card Module
Manufacturer: Honeywell
Part Number: 05701-A-0329
Product Type: 3-Channel DPCO Relay Card Module
Product Overview
The Honeywell 05701-A-0329 is a rugged Triple DPCO (Double Pole Change Over) Relay Card engineered as part of the System 57 series. It supports three independent relay channels, each equipped with dual Form C (SPDT) contacts, allowing versatile alarm, fault, inhibit, or general-purpose signaling.
Its 3U rack-mount form factor fits standard 19-inch enclosures, enabling straightforward integration into industrial safety and automation panels. The LED status indicators on each channel provide clear real-time feedback, reducing troubleshooting time and ensuring operational transparency.
Built for harsh industrial environments, the 05701-A-0329 combines high durability, stable performance, and CE-certified compliance, making it ideal for gas detection platforms and other mission-critical systems.

Rack Options
Racks are available in 4-slot, 8-slot, and 12-Slot versions. Racks are interchangeable between the Controller rack
and an I/O expansion rack, and all three versions shown in the following figure are available for either purpose.
8 and 12 slot I/O racks can be modified with additional slots for optional Reserve Power Supply and Power Status
Module.
Note: You can install redundant power on any 8 or 12 slot I/O rack.
Power Supply
The P01 Power Supply, shown in Figure 10. provides 5 Vdc and 24 Vdc to the backplane connectors in the local and
remote racks. Power Supply is used in each Controller Rack, I/O expansion racks and for all rack versions (4-slot,
8-slot, and 12-Slot).
The lower capacity P02 power supply is available for reduced I/O applications and for Redundant Controller rack
power.
P24 power supply provides 5VDC and 24VDC to satisfy the power requirements of a single controller with I/O, a
Remote I/O rack or a Redundant C75 CPU. The 60 watt capacity requires minimal de-rating of the available HC900
I/O modules.
A tool-secured door covers the voltage connections. An internal non-replaceable fuse limits supply current under
certain fault conditions.
Each power supply includes an internal 5.0-amp fuse that
is not field-replaceable. (An external fuse may be added
by the user. See page 25)
