The 8750-CA-NS is a Controller Carrier engineered for Emerson's PAC8000 Remote I/O system, providing the mounting platform and backplane connectivity for up to two 8521‑XX‑XX Controllers or EBIMs and a 8410‑NS‑PS Power Supply Monitor module. This 8750‑CA‑NS carrier distributes control signals across the Railbus and features a rear‑mounted screw terminal block for seven power fail inputs, enabling the 8410‑NS‑PS to monitor up to seven system power supplies and alert the controller to failures. With manual failover pushbuttons, integrated serial port connections, and Class 1 Div 2 / Zone 2 hazardous area certification, the 8750‑CA‑NS delivers robust, serviceable controller mounting for critical industrial automation applications.
Controller/EBIM Hosting – Provides mechanical mounting and backplane connectivity for up to two 8521‑XX‑XX controllers or EBIMs
Power Supply Monitoring – Accepts up to seven power fail input signals via screw terminals, enabling the 8410‑NS‑PS to alert the controller of power supply failures
Manual Failover Control – Two pushbuttons enable manual "change state" (master/standby/offline) switching for each controller/EBIM
Serial Communication Access – Two 9‑pin D‑type serial ports provide local connectivity for each controller/EBIM
Carrier Power Distribution – Distributes 12V DC power to the PSM and downstream carriers via a dedicated 6‑pin connector
Dual Controller/EBIM Capacity – Accommodates two 8521‑XX‑XX controllers or EBIMs for redundant or expanded control configurations
Integrated Power Supply Monitor Support – Accepts the 8410‑NS‑PS module with seven screw‑terminal power fail inputs for comprehensive system monitoring
Manual Failover Pushbuttons – Two "change state" buttons enable manual master/standby/offline transitions without software intervention
Serial Port Connectivity – Two 9‑pin D‑type female connectors provide local serial access to each controller/EBIM
Hazardous Area Certified – FM, CSA, and ATEX Category 3 approvals for Class 1 Div 2 / Zone 2 installation
Robust Construction – Painted 1.6mm ZINTEC steel carrier with epoxy resin woven glass laminate PCB for durability
Railbus Integration – Male Railbus connector enables seamless daisy‑chaining to I/O carriers
The 8750-CA-NS functions as the central mounting and interconnect backbone for the controller subsystem within a PAC8000 Remote I/O node. The carrier accepts up to two 8521‑XX‑XX controllers or EBIMs, which interface with the Railbus via the carrier's male‑out connector to communicate with downstream I/O carriers and modules.
A key feature of the 8750-CA-NS is its support for the 8410‑NS‑PS Power Supply Monitor module. Seven pairs of screw terminals at the rear of the carrier accept power "health" signals from external power supplies. The PSM monitors these signals and alerts the controller(s) to any power supply failure, enabling appropriate failover or shutdown responses. Unused terminal pairs must be shorted to prevent false alarms.
Two "change state" pushbuttons provide manual control over controller status. Pressing the button for a master controller transitions it to standby (if the current standby is healthy); pressing for a standby transitions it to offline; pressing for an offline or backup controller re‑synchronizes and returns it to standby. This enables manual failover, maintenance isolation, or re‑synchronization without software intervention.
The carrier also provides two 9‑pin D‑type serial ports for local connectivity to each controller/EBIM, and a 6‑pin connector at the top distributes 12V DC power to the PSM and other downstream carriers. Notably, this power connection does NOT supply the controllers/EBIMs themselves.
Q1: What modules can be mounted on the 8750-CA-NS?
The 8750-CA-NS accommodates up to two 8521‑XX‑XX controllers or EBIMs and one 8410‑NS‑PS Power Supply Monitor module.
Q2: What is the purpose of the "change state" buttons?
The two pushbuttons enable manual controller failover or status changes. Pressing the button for a master controller transitions it to standby (if the standby is healthy); pressing for a standby transitions it to offline; pressing for an offline or backup controller re‑synchronizes and returns it to standby.
Q3: How many power supplies can the 8750-CA-NS monitor?
The 8750-CA-NS provides seven screw‑terminal pairs for power "health" signals, enabling the 8410‑NS‑PS to monitor up to seven system power supplies.
Q4: What should be done with unused power health terminals?
Each unused terminal pair must be fitted with a shorting link to prevent a false alarm condition from being signalled to the controller/EBIM.
Q5: Is the 8750-CA-NS approved for use in hazardous areas?
Yes. The 8750-CA-NS is certified for Class 1, Division 2, Groups A‑D, T6 hazardous locations and Zone 2, IIC T6 hazardous locations. It complies with FM Class 3611, CSA C22.2 No. 213, and ATEX Category 3 (EN50021:1999) standards.
