961PB / 962PB
6-Channel Differential Profibus-DP Input Modules
• 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 powermore >
• Profibus-DP, RS-485 network up to 12Mbaud
961PB: 6 DC current input channels
962PB: 6 DC voltage input channels
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 many 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.
Features & Benefits
