CENTUM VP FIO Signal Termination
The ATA4S-00 provides a 16-point termination interface for analog field wiring associated with Yokogawa CENTUM VP FIO architecture. Pressure clamp terminals accept conductors within the specified 0.2 to 2.5 mm2 range and eliminate the requirement for specialized crimping tools or terminal lugs.
The supplied data identifies the assembly as suitable for analog input and analog output termination. A 24 VDC rated voltage and 500 VAC withstand voltage for 1 minute are specified for the terminal block. Insulation resistance is specified as 10 Mohm or greater at 500 VDC.
The supplied data also identifies hot-swappable signal wiring capability for signal verification and field-terminal connection during setup or maintenance. This describes the wiring interface and does not establish hot-swapping capability for the associated DCS I/O module.
Frequently Asked Questions (FAQ)
Q: How many signal channels are provided by the ATA4S-00? A: The terminal block provides 16 analog signal channels.
Q: What conductor size is accepted by the pressure clamp terminals? A: The specified conductor range is 0.2 to 2.5 mm2, corresponding to AWG 24 to AWG 12.
Q: Does the ATA4S-00 itself require power? A: No active power consumption is specified for the passive pressure clamp terminal block.
Field Installation Guidelines
Confirm the terminal block model and wiring assignment against the applicable Yokogawa CENTUM VP and FIO documentation before installation.
Use conductors within the specified 0.2 to 2.5 mm2 range.
Strip conductors according to the applicable terminal manufacturer's installation requirements and ensure that conductors are fully seated in the pressure clamp terminals.
Maintain correct polarity and channel identification for analog input and analog output circuits.
Keep analog signal wiring separated from high-voltage power and high-current switching conductors to reduce electrical interference.
Route cable shields according to the project grounding and instrumentation design. Avoid creating unintended shield-current paths.
Verify conductor retention mechanically after termination without applying excessive force to the terminal mechanism.
Perform continuity and insulation checks before connecting field wiring to energized DCS equipment.
Do not infer hot-swap capability for connected I/O modules solely from the stated hot-swappable signal-wiring feature.
For installations requiring ISA Standard G3 environmental performance, verify that the selected configuration and enclosure meet the applicable project environmental requirements.
