I/O modules

Overview

The 133819-01 Non-Isolated I/O Module provides six channels for temperature monitoring in Bently Nevada 3500 Series systems. It supports both Resistance Temperature Detectors (RTDs) and Thermocouples (TCs), delivering reliable, industrial-grade temperature measurements for machinery protection and process monitoring.

Key Features

• Six channels supporting RTD and TC inputs
• Compatible with 3500/60 & /61 Temperature Monitors
• Front panel LEDs: OK, TX/RX, Bypass
• Recorder outputs: +4 to +20 mA proportional to full-scale
• Non-isolated internal terminations
• RTD current source: 925 ±15 µA per transducer
• High-accuracy measurement: ±3°C at 25°C
