Product Introduction
Loose field wiring, damaged connectors, or missing terminal adapters can delay loop commissioning and make maintenance harder inside a DCS cabinet. The YOKOGAWA ATK4A-00 S1 is a 16-channel KS cable interface adapter used with Yokogawa CENTUM VP and CENTUM CS 3000 analog I/O modules.
It is not an active I/O card. Instead, it serves as the field termination interface between the I/O module and the field wiring, typically through a KS-type cable or terminal assembly. It is commonly referenced alongside 16-channel analog input modules such as AAI143 and AAV141, and is often ordered as part of a module/adapter combination.
Because the “S1” suffix is not fully documented in publicly available Yokogawa literature, the exact revision, connector type, and compatible module family should be confirmed against the existing unit or system documentation before replacement.

Key Selling Points & Differentiators
- 16-channel KS cable interface adapter for Yokogawa analog I/O modules.
- Suitable for field wiring replacement, cabinet maintenance, and spare stocking.
- Direct replacement when model, suffix, and paired I/O module match.
- Factory-sealed surplus inventory with visual QA and 12-month warranty.
- Not an active I/O card; it must be matched with the correct Yokogawa I/O module and base.
Quality Transparency SOP
- Visual inspection: Verify label “ATK4A-00 S1,” connector pins, housing, and terminal condition.
- Seal verification: Confirm original anti-static bag, packaging, and factory labeling.
- Suffix cross-check: Match ATK4A-00 S1 with the existing adapter; do not assume interchangeability with ATK4A-00, ATA4S, or ATA4D variants.
- Module pairing check: Confirm compatibility with the installed I/O module such as AAI143 or AAV141.
- Connector check: Inspect KS cable connector, locking mechanism, and pin alignment.
- Continuity check: Verify channel continuity and correct wiring before energizing the I/O module.
Technical Risk Avoidance
❗ Confirm the exact model and suffix. ATK4A-00 S1 may differ from ATK4A-00 or other ATK/ATA-series adapters.
❗ This is a field wiring adapter, not an I/O module. It cannot replace AAI, AAV, AAT, AAR, ADV, or other active I/O cards.
❗ Verify the paired I/O module. The adapter must match the channel count, signal type, and connector format of the installed card.
❗ Check KS cable compatibility. Mismatched cables or damaged connectors can cause channel faults or intermittent signals.
❗ Treat third-party descriptions as reference only. Some listings describe ATK4A-00 generically as a “DCS module” without confirming the adapter role.
Buyer’s FAQ
Is the YOKOGAWA ATK4A-00 S1 a genuine OEM part?
It is supplied as an original Yokogawa adapter when available, but the exact suffix and compatible module should be confirmed from the label.
What does the ATK4A-00 S1 do?
It is a 16-channel KS cable interface adapter used to connect Yokogawa analog I/O modules to field wiring.
Can it replace ATK4A-00 without “S1”?
Not automatically. The “S1” suffix may indicate a revision or option code, so the existing unit should be checked before substitution.
Does it include an I/O module?
No. ATK4A-00 S1 is a field termination/interface adapter and must be used with a compatible Yokogawa I/O module.
What warranty do you offer?
A 12-month warranty against manufacturing defects and DOA issues. Damage from incorrect module pairing, wrong cable, connector damage, or miswiring is not covered.
