Yokogawa ASR133-S00 RTD/POT Input Module

Product Model: ASR133-S00

Spare Model: S1

Product Parameters: RTD/POT Input Module

Product Description

The Yokogawa ASR133-S00 RTD/POT Input Module enables the integration of resistance-based temperature sensors (RTDs) and potentiometers (POTs) into digital control systems. It converts resistance changes from these sensors into digital data for process monitoring and control.

Key Features:

• Eight Isolated Channels: Handles eight independent RTD or POT signals simultaneously, preventing electrical interference between channels.
• Wide Resistance Range: Compatible with various RTD and POT types with a broad resistance range.
• RTD Sensor Compatibility: Supports common RTD types like Pt100, Pt500, and Ni100 for accurate temperature measurement.
• Selectable Input Type: Configurable for RTD or POT inputs based on application needs.
• Compact Design: Dimensions of 3.8 cm x 12.7 cm x 15.2 cm, saving space in cabinets or on machinery.
