Q1: What type of relay is used in the MC-TDOR12 module?
A1: The module utilizes high-quality mechanical relays rated for industrial use, typically Form A or Form C contacts, depending on configuration.

Q2: Can the MC-TDOR12 handle both AC and DC loads?
A2: It is primarily designed for DC load operation, but under certain configurations, it can handle low-voltage AC loads as long as they are within relay specifications.

Q3: What isolation level is provided between output channels?
A3: Each channel is galvanically isolated with a dielectric strength of approximately 1500 V RMS to ensure system safety and signal integrity.

Q4: Is this module hot-swappable within the Honeywell control system?
A4: No, the MC-TDOR12 is not hot-swappable. Power should be removed before replacement or maintenance to avoid damage or unintended actuation.

Q5: How does the module indicate output status?
A5: LED indicators on the module display the on/off status of each relay channel, allowing for quick operational verification.

Q6: What is the maximum output current supported per channel?
A6: Each relay channel can handle up to 2 amperes of continuous current, depending on ambient temperature and relay type.

Q7: Can the MC-TDOR12 be used in redundant output configurations?
A7: Yes, it can be integrated into redundant control architectures for increased system reliability and fail-safe operation.

Q8: Does the module require external power supply?
A8: The relay drive power is supplied through the system backplane; however, field power for connected devices must be externally provided.

Q9: How are field devices connected to the module?
A9: Field devices are wired directly to screw terminals on the FTA, ensuring secure and vibration-resistant connections.

Q10: What diagnostic features are supported?
A10: The module supports built-in diagnostic features such as channel health monitoring and relay status feedback through the control system.
