Intrinsic Safety (Ex i) Barriers & DIN-Rail Mounting Stability
The 8724-CA-PS module carrier incorporates a high-density printed wiring board encased in a rugged polycarbonate moulding engineered to maintain intrinsic safety (Ex i) creepage and clearance distances. When installed via standard 35 mm EN 50022 DIN-rail or flat panel 4-fixing configurations, the carrier establishes mechanical resistance against field vibration while isolating hazardous-area power supply rails. Internal bus traces limit voltage surge coupling and preserve signal integrity across 32-slot and 64-slot system address buses, mitigating protocol conversion latencies and electrical noise within PAC8000 field nodes.
Frequently Asked Questions
Q: Can the 8724-CA-PS carrier be installed directly onto both Top hat and G-section DIN rails?
A: Yes. The base moulding accommodates EN 50022 Top hat rails (7.5 x 35 mm or 15 x 35 mm) as well as EN 500 G-section rails without requiring auxiliary mounting brackets.
Q: Does the 8724-CA-PS carrier supply power without a power module installed?
A: No. The 8724-CA-PS is a passive structural carrier containing internal printed wiring; it requires an 8920-PS-DC power supply module to energize connected IS system buses.
Field Installation Guidelines
- Isolate all upstream power sources before handling the carrier to avoid electrical arcing in hazardous field areas.
- Snap the 8724-CA-PS securely onto the 35 mm DIN rail or secure it to a flat mounting plate using four panel-fixing fasteners.
- Ensure the protective grounding terminal is tied to the local earth bus using low-impedance copper conductors to maintain Intrinsic Safety (Ex i) compliance.
- Align the 8920-PS-DC power supply module with the carrier guide keyways and press firmly until the locking mechanism engages completely.
- Verify that all field wiring field terminals meet specified creepage and clearance distances according to PAC8000 installation standards.
