Yokogawa|AAR145-S50|RTD/POT Input Module

Description

Features

• 16 isolated channels for JIS Pt100 RTD (3-wire/4-wire) and 0–10 kΩ POT inputs
• High-precision signal conditioning with built-in linearization for RTD and POT signals
• Channel-to-channel and module-to-ground isolation (500 V AC) for noise immunity
• Direct connection via KS8 cable to MRT or TERT terminal boards
• Flexible configuration for RTD temperature measurement and potentiometer position sensing
