ABB 3BSE023607R1 TY801K01 Series Terminal Unit

Configured for high-density interconnectivity in S800 I/O control architectures, the ABB 3BSE023607R1 (TY801K01) Terminal Unit provides direct physical/electrical execution of field-to-backplane signal termination, circuit grouping, and modular bus distribution.

Hardware Specifications

ABB Industrial Control Characteristics

• Backplane bus communication velocity: The terminal unit interfaces with the S800 I/O backplane to facilitate signal propagation between field sensors and the I/O module bus. This velocity is mandatory to ensure that discrete and analog signals reach the controller within the required scan-time window.
• Profinet / EtherNet/IP deterministic networks: The unit supports the physical infrastructure required for deterministic network deployments in ABB control systems. It maintains the signal path integrity required for high-speed fieldbus connectivity, ensuring minimal latency in data exchange.
• I/O density scaling: The 15.5 mm width allows for high-density mounting within the I/O rail. This scaling is mandatory for optimizing cabinet space in large-scale control systems where individual signal termination is required for every I/O point.
• Firmware flash compatibility: As a passive physical component, the unit supports existing system-wide firmware configurations, ensuring it remains compatible with all S800 I/O module revisions without requiring logic-level modifications.

Frequently Asked Questions

Q: Does the TY801K01 support hot-swapping within the S800 rack?

A: Yes, the unit is designed for mechanical compatibility with the S800 I/O system, but power must be isolated from the associated I/O module before performing maintenance. Ensure that the field wiring is properly secured and identified before disconnecting to prevent wiring errors upon re-insertion.

Q: Can this terminal unit be used with any S800 I/O module?

A: Compatibility is limited to specific S800 module types. Always consult the ABB S800 I/O hardware manual to verify that the TY801K01 is the correct physical interface for the specific module being installed, as mismatching terminal units can lead to backplane connector damage or signal misrouting.

Field Installation Guidelines

• Mounting: Snap the unit onto the standard DIN-rail and secure it to ensure a vibration-resistant installation. Rigid mechanical mounting is mandatory to maintain stable pin contact between the unit and the I/O module.
• Grounding: Terminate the shield of field-side cables to the designated ground terminal provided on the unit. A low-impedance connection to the cabinet’s safety earth bus is mandatory to ensure effective electromagnetic shielding and to prevent ground loops.
• Wiring: Connect field signals using ferrules to ensure secure contact within the terminal screw clamps. Maintain a minimum separation of 150 mm from high-power AC lines to prevent induced interference, which is mandatory to protect signal measurement accuracy in the control system.
