Yokogawa AIP830-101 CENTUM VP Operation Keyboard

Configured for process navigation and single-loop control in CENTUM VP Human Interface Stations, the Yokogawa AIP830-101 (AIP830 Operation Keyboard) provides direct physical/electrical execution. The desktop flat-panel hardware processes tactile operator keypresses and transmits command data directly to industrial host PCs via dual USB interfaces, facilitating real-time monitoring of faceplate control windows, trend displays, and alarm summaries.

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

While the keyboard processes digital human-machine interface keystrokes, the host CENTUM VP software routes these operator commands directly to field controller cards managing 4-20 mA HART loop protocol lines. Internal signal buffering prevents noise cross-talk between USB communication channels and adjacent operator console sub-assemblies. Furthermore, robust channel-to-channel isolation within the connected DCS I/O racks isolates the host PC from field voltage surges during high-density switching operations.

Frequently Asked Questions

Q: Does the keyboard require an external AC power supply adapter during operation?

A: No, the hardware operates entirely as a USB bus-powered device, drawing 5 VDC at up to 1 A directly from the host PC ports.

Q: How do technicians connect the unit to the Human Interface Station host PC?

A: Connect both standard USB Type A connectors directly into available USB ports on the industrial PC running CENTUM VP or CENTUM CS 3000 software.

Q: Can the keyboard function across extreme ambient temperature swings?

A: Operating limits span strictly from +5 to +40 deg C to ensure accurate key contact responses during active control room operation.

Field Installation Guidelines

  1. Position the keyboard on a stable, flat desktop surface within reach of the Human Interface Station console cables.
  2. Inspect the USB connectors and cabling for mechanical debris or insulation damage prior to connection.
  3. Insert both USB Type A cables firmly into host PC ports, ensuring complete contact seating.
  4. Route interface cabling away from high-voltage power conduits and heavy inductive loads to prevent electromagnetic interference.
  5. Clean the membrane key surface using a dry, non-abrasive cloth without applying chemical solvents or liquid sprays directly onto key seals.
  6. Confirm system driver recognition and verify that dedicated function keypresses initiate the corresponding DCS alarm and trend displays.
