900RTC-L010 | Honeywell | RTP Cable Assembly

The Honeywell 900RTC-L010, also cataloged as the 900RTC Cable Assembly, operates as a dedicated hardware component for low-voltage signal and power interconnection within Honeywell control system architectures.

Hardware Specifications

Process Control & Network Integration

The cable assembly establishes point-to-point physical interface links between central process controllers and Remote Termination Panels (RTPs). Built-in industrial-grade EMI shielding preserves signal integrity along 4-20 mA HART loop protocol connections and low-voltage discrete I/O channels. Reinforced connector strain reliefs maintain conductor alignment under continuous cabinet vibration, preventing high-frequency noise insertion and preserving channel-to-channel isolation parameters across backplane terminal buses.

Frequently Asked Questions

Q: Can the 900RTC-L010 cable assembly be connected or disconnected while system power is active?

A: Main backplane and I/O field power must be de-energized prior to connecting or disconnecting cable assemblies to prevent transient ground faults or pin electrical arcing.

Q: Is this cable rated for high-voltage AC I/O module interconnections?

A: No, the 900RTC-L010 is rated exclusively for low-voltage signal paths. High-voltage AC or relay switching circuits require dedicated high-voltage RTP interface assemblies.

Q: What shielding mechanism is utilized to prevent signal corruption?

A: The harness incorporates comprehensive industrial EMI/RFI shielding paired with grounded drain wire terminations to attenuate high-frequency industrial field interference.

Field Installation Guidelines

1. De-energize control system supply and field excitation voltage before attaching or removing cable assemblies.
2. Maintain a minimum bend radius during installation to prevent conductor strain or internal shield degradation.
3. Route the low-voltage cable harness in dedicated wire ducts, maintaining physical separation from high-voltage AC conductors and motor leads.
4. Insert cable connectors into corresponding module and RTP ports until latching mechanisms lock completely.
5. Verify operating ambient temperatures within the enclosure remain within -20 to 60 deg C boundaries.
