Yokogawa AAR145-S50S1 Input module

Supported Signals: RTD (Pt100 Ω) and POT (0 to 10 kΩ) signals, covering most industrial 

temperature and position sensing needs.

Channel Capacity: 16 isolated channels, enabling independent signal sampling without cross-

interference.

Isolation Performance: Channel-to-channel and channel-to-chassis isolation, ensuring signal 

integrity in high-electromagnetic interference (EMI) environments.

Power Consumption: Max 350 mA (5 V DC), energy-efficient for large-scale system deployment.

Operating Temperature: 0 to 60 °C (standard); optional -20 to 70 °C for extreme industrial 

conditions.

Environmental Resilience: Complies with ANSI/ISA S71.04 G2 (standard) for corrosive gas resistance, and withstands vibration (2.0 m/s², 14–100 Hz) and static electricity (4 kV contact discharge, 8 kV 

aerial discharge).

Global Certifications: Compliant with CSA, CE Marking, EAC Marking, and RCM safety/EMC 

standards, facilitating international project deployment.

Explosion Protection: Supports CSA Non-Incendive and FM Non-Incendive standards, suitable for 

hazardous location installations (when paired with appropriate barriers).

Isolated channel design eliminates ground loop interference and signal crosstalk, ensuring accurate 

measurement of RTD/POT signals—critical for precision control in industries like petrochemicals, 

power generation, and pharmaceuticals.

Wide compatibility with Pt100 RTDs (common industrial temperature sensors) and 0–10 kΩ 

potentiometers (position sensors) makes it versatile for mixed-signal applications.

Node Compatibility: Works seamlessly with ESB Bus Node Units (ANB10), Optical ESB Bus Node 

Units (ANB11), and Field Control Units (AFV30/AFV40), integrating effortlessly into 

Yokogawa’s CENTUM VP system.

Wiring Flexibility: Compatible with dedicated cables (KS8) and terminal boards (MRT, TERT), 

supporting both direct wiring and terminal board connections for diverse installation scenarios.

Dual-Redundant Support: Eligible for dual-redundant configurations, enhancing system availability 

for mission-critical applications.

Operates stably in harsh environments with wide temperature ranges (5–95% RH, non-condensing) 

and resistance to dust (0.3 mg/m³ or less) and corrosive gases, reducing downtime in challenging 

on-site conditions.

Compact rack-mountable design optimizes cabinet space utilization, ideal for dense I/O 

configurations.
