4. Product Introduction (Anti-Template)
When an intrinsically safe PAC8000 node needs a dedicated power supply module, the 8724-CA-PS provides the mechanical and electrical carrier. It accepts a single 8920-PS-DC power supply module and mounts either on standard DIN rail or directly to a panel.
The carrier includes the necessary railbus connectors so the power supply can feed the node while supporting both 32-slot and 64-slot addressing schemes. Its polycarbonate housing and printed-circuit construction are designed for the environmental and safety requirements of process I/O systems installed in or near hazardous areas. It is a pure carrier—no active electronics beyond the interconnects—so reliability depends on correct installation and the paired 8920-PS-DC module.
5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full marking (8724-CA-PS), presence of railbus connectors, mounting hardware condition, and absence of cracks or damaged terminals. Photograph labels.
- Live Rig Testing – Install the matching 8920-PS-DC module, mount on DIN rail or panel, apply power, and verify correct bus communication and power distribution to a test node (if available).
- QA & Anti-Static Packaging – After inspection, protect connectors, clean the carrier, and seal in anti-static or protective packaging with desiccant.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial process-control carriers. Packaging must protect against mechanical shock; export documentation is prepared to minimize customs delays.

6. Technical Pitfalls & Integration Warnings
Module Compatibility – The carrier is designed exclusively for the 8920-PS-DC power supply module. Inserting any other module can damage the carrier or the module and voids the safety certification.
Addressing Configuration – Incorrect setting of 32-slot versus 64-slot addressing prevents the power supply from being recognized by the node controller.
Mounting and Grounding – Poor DIN-rail contact or inadequate panel grounding can introduce noise or compromise the intrinsically safe system integrity. Follow the manufacturer’s grounding guidelines.
Hazardous-Area Certification – The carrier itself is part of a certified system. Substituting non-approved components or incorrect installation methods invalidates the hazardous-area approval.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified 8724-CA-PS?
Stock units typically ship within 1–5 business days after verification. Longer lead times apply if the item must be sourced from secondary inventory.
What module does the 8724-CA-PS accept?
One 8920-PS-DC intrinsically safe system power supply module.
How is it mounted?
Either on standard DIN rail (top-hat or G-section) or directly to a flat panel using four fixings.
Does it support both 32-slot and 64-slot systems?
Yes. The carrier is address-capable for both 32-slot and 64-slot PAC8000 nodes.
Is the carrier itself an active power supply?
No. It is a passive carrier that holds and interconnects the 8920-PS-DC power supply module.
What is the approximate size and weight?
Approximately 93 × 168 × 35 mm and 195 g.
Is it suitable for hazardous areas?
It is designed for use as part of a PAC8000 system installed in Class I Division 2 or Zone 2 locations when used with the appropriate certified modules and following the system installation rules.
