Product short description:
  • Thermocouple or Millivolt Signals
  • 4 or 6 input channels, thermocouple or DC millivolts (user-selectable)
  • 12 to 36V DC  power
  • Profibus-DP, RS-485 network up to 12Mbaud
[DISPLAY_ULTIMATE_PLUS]

Description

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

Input Ranges

Thermocouple (user-selectable type)
Type J, K, T, R, S, E, B, or N
DC Millivolts (user-selectable range)
±100mV or ±1V DC

Network Communication

Profibus-DP, RS-485 network up to 12Mbaud

Power Requirement

12 to 36V DC supply required

Approvals

Profibus PNO certified.
CE marked. UL, cUL listed.
Class I; Division 2; Groups A, B, C, D

Input Filter Bandwidth: -3dB at 3Hz, typical

Environmental

Ambient Temperature:
Operating: -25 to 70°C (-13 to 158°F).
Storage: -40 to 85°C (-40 to 185°F)
Relative Humidity: 5 to 95%, non-condensing
Isolation:
1500V AC for 60 seconds or 250V AC continuous
3-way isolation between I/O, network, and power

  • 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 more precise temperature measurements
  • Thermocouple break detection (upscale or downscale) identifies sensor wiring failures
  • High-resolution 16-bit sigma-delta A/D converters ensure precise, high accuracy measurements
  • Compact packaging with pluggable terminals saves space and simplifies wiring
  • Wide operational temperature range permits installation in extreme environments: -25 to 70°C (-13 to 158°F)
