Yokogawa ATB3A-00 S1 KS Cable Interface Adapter

Configured for terminal signal conversion in CENTUM VP and CENTUM CS 3000 systems, the Yokogawa ATB3A-00 S1 (ATB3A-00 KS Cable Interface Adapter) provides direct physical/electrical execution. The hardware bridges multi-channel field wiring to system I/O modules via an integrated 50-pin KS-type connector interface. It accepts 4-20 mA current loops, DC voltage, RTD, and thermocouple signal connections across M4 screw terminals, facilitating deterministic data transfer between field transmitters and Field Control Unit (FCU) backplanes.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The adapter module incorporates dedicated wiring pathways designed to maintain channel-to-channel isolation across multi-core signal runs. Built to meet EN 61000-6-2 electromagnetic immunity standards, internal dielectric barriers provide 500 VAC isolation between terminal points and logical ground planes. This configuration prevents ground potential shifts and industrial noise spikes from interfering with 4-20 mA HART loop protocol signaling when interface cables route process variables directly to CENTUM I/O modules.

Frequently Asked Questions

Q: How does the module interface with Field Control Unit (FCU) I/O cards?

A: Technicians connect multi-conductor Yokogawa KS series signal cables directly to the onboard 50-pin KS connector, linking the terminal block assembly directly to system I/O cards.

Q: Does the unit require an external power feed to process field signals?

A: No, the adapter operates as a passive wiring interface board, although connected 24 VDC loop power passes directly through the terminals to power active field instruments.

Q: What grounding procedure prevents ground loops across the KS interface cable shield?

A: Field cable drain wires must terminate directly to the dedicated shield grounding terminal on the mounting frame to maintain a single-point system ground path.

Field Installation Guidelines

Position the adapter housing onto standard DIN rail or panel surfaces and snap the integrated locking clips securely into place.
Verify that all 24 VDC field loop power sources are fully de-energized prior to connecting wiring harnesses.
Terminate individual field sensor conductors onto the M4 screw terminals, applying a fastening torque of 1.2 Nm.
Attach the multi-core KS signal cable plug to the 50-pin KS interface connector, securing the side latching screws to prevent physical disengagement.
Route field cables in separate wire ducts away from high-voltage AC power lines to minimize electromagnetic noise coupling.
Perform insulation resistance measurements with a 500 VDC tester prior to initial power-up to confirm line isolation integrity.
