4-20 mA HART Loop Protocol and Channel-to-Channel Isolation Support
Engineered for modular ControlWave PAC expansion, the 396352/396560 series base chassis provides parallel bus routing and backplane power distribution across eight I/O slots. Embedded low-impedance traces preserve channel-to-channel isolation across plugged analog input and output cards, protecting sensitive 4-20 mA HART signals and discrete lines from backplane cross-talk and common-mode noise.
Frequently Asked Questions
Q: Can I/O modules installed in the 396560-01-6 base chassis be inserted or removed under power?
A: No, backplane power to the chassis must be turned off before inserting or removing I/O modules to prevent electrical transients and logic disruption on the internal communication bus.
Q: How is backplane bus shielding maintained across the 8 slots of the chassis?
A: Grounding continuity across all 8 slots is achieved through the integrated copper ground plane embedded within the printed circuit board backplane, which connects directly to the chassis earthing lug.
Field Installation Guidelines
Mount the 8-slot base chassis securely to a grounded micro panel or 19-inch rack enclosure using standard M5 mounting screws.
Connect a dedicated low-impedance copper ground strap from the chassis earthing terminal to the primary Instrument Earth (IE) bus bar.
Align I/O modules with the card guide tracks for each designated slot and press firmly to seat the backplane multi-pin connectors.
Verify that total backplane current draw across all 8 installed modules does not exceed maximum power supply ratings before energizing the system.
