Description
Product Overview
Part Number: AAT141-S00 Manufacturer: Yokogawa (Yokogawa Electric, Japan) Product Series: CENTUM VP DCS, FIO Field I/O Module Type: TC/mV/RTD Multi-type Temperature Input Module AAT141-S00 is a 16-channel fully isolated temperature & millivolt input module for Yokogawa CENTUM VP FIO nodes. It supports flexible mixed signal acquisition: thermocouple (TC), millivolt (mV) and 3-wire Pt100 RTD. Each channel can be independently configured for different sensor types. Built-in cold junction compensation for thermocouple measurement. It converts weak field temperature signals into digital data and communicates with FCS controller via ESB bus. Widely used in petrochemical, power, oil & gas and chemical plants for furnace, reactor and pipeline temperature monitoring. Supports hot swap and dual-redundant installation.

Engineer Notes
- AAT141-S00 belongs to FIO series I/O module for CENTUM VP, not compatible with old CS3000 system.
- Supports mixed sensor configuration, each of the 16 channels can be separately set to TC, mV or Pt100.
- Built-in cold junction compensation eliminates external reference junction box for thermocouple application.
- Supports sensor burnout detection, can trigger alarm when thermocouple or RTD sensor wire is broken.
- Can be installed as dual redundant pair; automatic switchover upon module fault without interrupting temperature data acquisition.
- Hot-swap function allows module removal and replacement while DCS online, no system shutdown required.
- Use matched Yokogawa ATT4S / ATT4D terminal boards for field wiring; shielded twisted-pair cable is strongly recommended for weak temperature signals to reduce noise.
- Check module LED indicators for power, ESB communication and channel fault status during commissioning and routine maintenance.

Buyer FAQ
Q: Is AAT141-S00 new original? A: We supply brand new original Yokogawa units, 12-month warranty, factory test certificate available on request.
Q: What does suffix S00 mean? A: S = standard type; 00 = basic non-explosion-proof version for FIO node.
Q: What is the difference between AAT141-S00 and AAR181-S50? A: AAT141-S00:16 channels, supports TC/mV/Pt100 mixed input. AAR181-S50:12 channels, only for Pt100 RTD.
Q: Can AAT141-S00 work in redundant configuration? A: Yes, two AAT141-S00 modules can be configured as dual redundant pair with ATT4D redundant terminal block.
