Key Features:

These modules provide an isolated Profibus-DP network interface for up to six input channels.
The differential inputs eliminate ground noise and each terminal block includes precise temperature measurements is delivered through a cold junction compensator. Multi-range inputs accept signals from a variety of sensors and devices. High-resolution, low noise, A/D converters to deliver high accuracy and reliability.

• Standard Profibus-DP network communication with industry-standard ASIC (Siemens SPC3)
• 6-input stand-alone module is very economical
• Universal inputs support a variety of sensors
• Built-in CJC sensor on each terminal block produces moreprecise temperaturemeasurements
• Thermocouple break detection (upscale or downscale) identifies sensor wiring failures
• High-resolution 16-bit S-DA/D converters ensureprecise, high accuracy measurements
• Compact packaging with pluggable terminals saves space and simplifies wiring
• Wide operational temperature range permits installation in extreme environments
