Yokogawa AAT141-S00 Analog Temperature Input Module
- Product Introduction: It is a 16 – channel analog temperature input module designed for Yokogawa’s CENTUM VP distributed control system. It directly accepts signals from thermocouples and RTDs, converts them into digital signals for the DCS controller, and is suitable for temperature measurement in industrial processes.
- Technical Specifications:
- Number of Channels: 16 isolated channels.
- Input Signal: Thermocouple (K, J, T, E, R, S, B, etc.), RTD (Pt100, JPt100).
- Accuracy: ±0.1% of full scale for thermocouple; ±0.05% of full scale for RTD.
- Cold Junction Compensation: Built – in, accuracy ±0.2°C.
- Working Voltage: 24V DC, power consumption ≤ 350mA.
