Redundant Power and Backplane Configuration
The FC-IOCHAS-0002R provides a chassis structure for mounting I/O modules and supporting redundant power supply modules. The 21-slot arrangement defines the available mechanical positions for I/O module installation.
The chassis supports up to two power supply modules. However, the supplied data does not specify power-sharing behavior, automatic switchover time, backplane current capacity, or module hot-swap conditions. Engineers must verify these parameters against the applicable Honeywell system documentation before commissioning.
Frequently Asked Questions
Q: How many I/O modules can the FC-IOCHAS-0002R accommodate?
A: The chassis provides 21 I/O module slots. The actual usable configuration depends on the system architecture and the compatibility of the installed modules.
Q: Does the FC-IOCHAS-0002R support redundant power supplies?
A: Yes. The supplied specifications identify support for up to two power supply modules. They do not define the redundancy control logic or power supply switchover performance.
Q: What environmental conditions does the chassis support?
A: The specified operating temperature range is -40 deg C to +70 deg C. The chassis supports 5-95% relative humidity without condensation, vibration from 5 to 500 Hz at 2 g RMS, and a shock rating of 30 g peak for 11 ms.
Field Installation Guidelines
- Rack mounting: Install the chassis in a compatible 19-inch rack or cabinet. Confirm that the mounting hardware supports the chassis weight and that the rack provides adequate mechanical stability.
- Power wiring: Connect the 24 V DC supply according to the approved Honeywell wiring documentation. Verify polarity and supply tolerance before energizing the chassis.
- Module installation: Confirm each I/O module’s slot assignment and mechanical compatibility before insertion. Do not force modules into incompatible positions.
- Redundant power arrangement: Install the approved power supply modules in the designated positions. Verify the system’s redundancy and load-sharing requirements using the relevant technical manual.
- Grounding: Connect the chassis protective earth and cabinet bonding conductors according to the applicable installation standards. Maintain continuity between the chassis and the cabinet grounding system.
- Cable routing: Keep power wiring separated from sensitive signal wiring where the cabinet design permits. Secure cables to prevent mechanical strain on module connectors and termination points.
- Environmental clearance: Maintain sufficient cabinet clearance for ventilation, inspection, and module removal. Prevent condensation and avoid installation conditions outside the specified temperature and humidity ranges.
- Commissioning checks: Inspect mounting, module seating, power polarity, grounding, and wiring before applying power. Verify the installed configuration against the approved system drawings.
