4 CH.AI/P 0-20MA XTR SERIES

4-channel analog input; 0 … 20 mA; Single-ended; Extreme


This analog input module processes standard 0–20 mA signals.
The input signal is electrically isolated and is transmitted with a resolution of 12 bits.
The internal system supply powers the module.
The input channels of the module have a common ground potential.
The device is ideal for operation in extreme environments thanks to:

• An extended temperature range
• Greater immunity to impulse voltages and electromagnetic interference
• Higher vibration and shock resistance
