Yokogawa ANB10D-420/CU2T/NDEL ESB Bus Node Unit

Configured for high-speed backplane communication in Yokogawa CENTUM VP DCS networks, the Yokogawa ANB10D-420/CU2T/NDEL (ANB10D ESB Bus Node Unit) provides direct physical layer interfacing between Field Control Units and FIO modules. The unit executes deterministic data transfer over dual-redundant Enhanced System Bus architecture while managing distributed I/O power distribution and bus termination functions.

Foundation Fieldbus H1 Segment Coupling

The ANB10D interfaces with field devices utilizing Foundation Fieldbus H1 protocols through compatible FIO modules. The unit supports channel-to-channel isolation barriers to suppress ground loop currents. When configured with the /CU2T option, the integrated termination resistors maintain 100 ohm characteristic impedance matching for the ESB bus physical layer, ensuring deterministic macrocycle execution without signal reflection artifacts.

Frequently Asked Questions

Q: Does the /NDEL software license permit hot-swapping of I/O modules?

A: No. The /NDEL license governs node expansion capacity within the DCS architecture. Physical hot-swap capability is determined by the specific FIO module installed; standard analog input modules do not support live removal.

Q: What is the maximum permissible voltage fluctuation for the 220-240 V AC input?

A: The power supply accepts a permissible input range of 187 to 264 V AC. Operation outside this range triggers an internal fault status on the ESB bus diagnostic registers.

Q: Is the /CU2T terminator required if the node is mid-bus?

A: No. The /CU2T connector unit is mechanically required for installation, but the internal termination resistors are only jumper-activated for the final node in the daisy-chain topology.

Field Installation Guidelines

Secure the unit to the 19-inch rack using four M5 screws. Ensure the rack frame is bonded to the plant functional ground grid with a conductor of less than 100 ohm resistance. When installing the /CU2T connector, verify that the ESB bus cable shield is terminated with 360-degree circumferential contact at the connector hood to prevent EMI ingress. For dual-redundant configurations, both power supply modules must be energized simultaneously to achieve the specified 200 VA load capacity.
