Description

The Honeywell 900RTA-L001 is a Remote Terminal Panel (RTP) module designed for use within the ControlEdge HC900 process automation system. This module serves as a critical interface component for analog input signal processing, providing reliable connectivity and signal conditioning for field instrumentation. It is specifically engineered to support various RTD and low-voltage input types, excluding thermocouple inputs.

Features

• Supports 80mA analog input configurations.
• Integrated fuse protection per circuit (80mA, time-lag type).
• Selectable shunt resistor (250 Ohms, 0.05%, 15ppm) per circuit.
• Common supply terminals with selectable power per circuit for transmitter support.
• Designed for high-accuracy signal acquisition in industrial control environments.

Technical Specifications

Installation Guidelines

• Ensure the system power is disconnected before installing or removing the RTP module to prevent electrical damage.
• Mount the module in a clean, dry, and vibration-free environment consistent with HC900 rack specifications.
• Use shielded twisted-pair cabling for analog signals to minimize EMI/RFI interference.
• Ensure proper grounding of the terminal panel to the system common ground to maintain signal integrity and safety.
• Verify that all field wiring is securely terminated and that the correct fuse type is installed for circuit protection.

FAQ

What is the primary function of the 900RTA-L001?

The 900RTA-L001 is a remote terminal panel module used in the Honeywell HC900 system to facilitate analog input signal connections, including RTD and millivolt signals, while providing circuit-level protection and power distribution.

Are thermocouple inputs supported by this module?

No, this specific model (900RTA-L001) is designed for RTD and low-voltage inputs and does not support thermocouple input types.

What is the purpose of the selectable shunt resistor?

The selectable 250 Ohm shunt resistor allows the module to be configured for current-loop inputs (e.g., 4-20mA) by converting the current signal into a voltage signal that the analog input module can process.
