More Information

Overview Manuals Specifications KS Cable Link Channel Matching Cabinet Review

Features:

  • KS cable boundary: The adapter connects compatible analog FIO hardware to KS1 or KS2 cabling.
  • Variable channel scope: The official module list includes 16-point and 8-point devices.
  • Compact interface body: Cabinet review should retain cable bend and connector access.

ATK4A is an interface adapter rather than a field terminal block; its purpose is to connect compatible analog FIO modules through KS cabling.

Channel capacity depends on the selected module, so the adapter cannot be specified from the base model alone.

Verify the module, KS cable type, suffix, and cabinet routing before a purchase or replacement.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

KS interface checks

  • Cable family: Confirm whether the project uses KS1 or KS2.
  • Connector access: Preserve service clearance and cable bend radius.
  • Cable record: Keep the cable identifier with the loop documentation.
  • Adapter role: Do not treat ATK4A as a pressure-clamp terminal block.

Module and channel review

  • Sixteen-point modules: Match the exact listed module before ordering.
  • Eight-point modules: AAI135, AAI835, AAP135, and AAB141 require the applicable channel review.
  • Signal service: Keep the adapter within the official analog I/O scope.
  • Cross-family use: Do not infer digital-module compatibility.

Installation planning

  • Adapter dimensions: Use the official body size for cabinet clearance only.
  • Cable routing: Check KS cable entry and service access.
  • Suffix: Verify the complete no-surge ordering suffix.
  • G3 option: Confirm /G3 from the installed or project configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How do buyers decide whether ATK4A should use a KS1 or KS2 cable?
Use the installed cable designation and Yokogawa project documentation; do not select the cable from the adapter appearance.
Which information should be included in an ATK4A RFQ?
Provide the connected module, KS cable type, channel count, full suffix, /G3 requirement, quantity, and destination.
Why can ATK4A channel capacity be 8 or 16 points?
The capacity depends on the connected analog FIO module listed in the official Yokogawa specification.
Can ATK4A be used with digital FIO modules?
No digital compatibility is claimed here. Match ATK4A only to the official analog module list.
What should engineers check before replacing ATK4A?
Check the module identity, KS cable, connector orientation, cabinet clearance, suffix, and loop documentation.
Is ATK4A a direct substitute for a pressure clamp terminal block?
No. It is a KS cable interface adapter and has a different field-interface role.
Where can procurement get the ATK4A datasheet and sourcing support?
Use the PDF in Manuals and send Apter Power the module and cable details with the RFQ.
