Yokogawa AAP135-S00 S2 CENTUM VP Pulse Input / Analog Input Module

Configured for high-accuracy signal acquisition in CENTUM VP control systems, the Yokogawa AAP135-S00 S2 (AAP135 Pulse Input / Analog Input Module) provides direct physical/electrical execution across 16 channels. The hardware processes 4-20 mA DC and 1-5 V DC analog field signals alongside pulse inputs from flow meters, transmitters, and discrete field devices via the ATK4-00 S1 connector terminal assembly. Channel isolation protects local micro-controller backplane circuits against high-voltage surges and field ground potential loops. Conformal coating applied per the S2 suffix code resists chemical corrosion and moisture ingress in harsh field cabinet environments.

Process Loop & Signal Isolation Characteristics

The module incorporates 1500 VAC optical isolation per channel to integrate with 4-20 mA HART loop protocol instruments and high-speed pulse measurement circuits. Galvanic decoupling prevents ground loops from corrupting the 16-bit analog-to-digital converters during continuous scan cycles. Built-in diagnostic routines monitor power rail tolerances and signal continuity, reporting channel-level fault alarms directly to the Field Control Unit logic.

Frequently Asked Questions

Q: Can the AAP135-S00 S2 be replaced while the system rack remains energized?

A: Hot-swapping is supported. Technicians can remove and insert the module online without disrupting system logic execution or adjacent I/O modules on the backplane, provided the ATK4-00 S1 terminal block is unlatched cleanly.

Q: What environmental protection does the S2 suffix variant provide?

A: The S2 suffix indicates an industrial conformal coating applied across internal circuit assemblies. This coating guards components against corrosive gases, high relative humidity, and atmospheric particulate contamination.

Field Installation Guidelines

Power down the external auxiliary field power loop before attaching or removing the ATK4-00 S1 terminal connector.
Align the module card guide rails with the designated slot position on the Field Control Unit base plate.
Push the card firmly into the chassis slot until top and bottom retention latches engage with a mechanical click.
Fasten the ATK4-00 S1 terminal pin assembly securely to the front panel header to maintain proper contact impedance.
Terminate field wiring cable shields at the cabinet grounding rail using low-impedance clamps to establish a single-point earth ground.
Maintain a minimum separation clearance of 200 mm between field analog input cables and high-voltage AC power wiring.
