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.
