Product short description:
  • DC Current or DC Voltage Signals
  • 6 input channels, 0 to 20mA in 3 selectable ranges (0 to 20 amps AC with optinal AC sensor) or ±78mV to ±10V DC with eight range options
  • 12 to 36V DC power
  • Profibus-DP, RS-485 network up to 12Mbaud

These modules provide an isolated Profibus-DP network interface for six analog input channels. Differential inputs eliminate ground loops and thus the need for isolators in any applications.

961PB, 962PB: 6-Channel Differential Profibus-DP Input Modules Description

These modules provide an isolated Profibus-DP network interface for six analog input channels. Differential inputs eliminate ground loops and thus the need for isolators in any applications. Multi-range inputs accept signals from a variety of sensor and devices. High-resolution, low noise, A/D converters deliver high accuracy and reliability.
