Country of Origin
This circuit board is manufactured in the United Kingdom by J&S Sieger Ltd, a brand now integrated into the Honeywell Analytics safety portfolio.
Application Fields
The 01300-C-1027 board is primarily used in hazardous area monitoring including:
- Offshore Platforms: Detecting combustible or toxic gas leaks in extreme environments.
- Petrochemical Refineries: Managing safety-critical alarms in processing units.
- Confined Space Monitoring: Providing logic for localized gas sensing networks.
- Industrial Manufacturing: Protecting personnel in facilities using volatile chemicals.
Product Usage Instructions
- Power Isolation: Ensure the rack or control system is completely powered down before removing or inserting the circuit board to avoid electrical arcing.
- Alignment: Slide the card into the designated slot guides of the rack, ensuring the rear edge connector aligns perfectly with the backplane.
- Seating: Apply firm, even pressure until the board is fully seated. Secure any locking levers or screws if provided.
- Calibration: After installation, the associated gas sensor channel may require re-calibration to ensure the new board accurately interprets the sensor millivolt or milliamp signals.
- Testing: Perform a functional “bump test” by applying a known gas concentration to the sensor to verify the board triggers the correct alarm relays.
Product Technical Description
The 01300-A-449 Issue 11 represents a mature and highly stable iteration of the Sieger gas control logic. Technically, it functions as a signal comparator and amplifier, taking low-level signals from remote gas detectors and comparing them against user-defined trip points. The Issue 11 revision includes optimized component layouts for better heat dissipation and improved noise immunity, ensuring the system does not trigger false alarms due to electromagnetic interference in heavy industrial settings.
Q&A (Common Questions)
Q: Is the Issue 11 board backward compatible with older Issue versions? A: Generally, yes. Issue 11 is a refined version of the 01300-A-449 series and is designed to be a direct drop-in replacement for earlier revisions in the same system series.
Q: What does the “C-1027” suffix signify? A: The “C” suffix usually refers to a specific configuration or assembly code that dictates the alarm thresholds or output types pre-set at the factory.
Q: Can this board be used for oxygen deficiency monitoring? A: Yes, if configured with the appropriate sensor and calibrated for 0-25% volume levels, the board logic can handle both flammable and toxic/oxygen detection.
Q: Are there diagnostic indicators on the board? A: Most versions of this board feature onboard LEDs to indicate “Power,” “Fault,” and “Alarm” status for immediate visual troubleshooting.
