Product introduction:
The AI820 Analog Input Module has 4 differential, bipolar current/voltage inputs. Each channel can be either a voltage or current input.
The current inputs can withstand an accidental maximum normal mode 30 V d.c. connection. To protect the current input circuit against dangerous input levels, that is, by accidentally connecting a 24 V source, the resistor rating of the 250Ω current sense resistors is about 5 Watts. This is intended only to temporarily protect one channel at a time.
The module distributes the external transmitter supply to each channel. This adds a simple connection (with extended MTUs) to distribute the supply to external 2 wire transmitters. There is no current limiting on the transmitter power terminals.

The TU810 (or TU814) Compact MTU has terminals for 24 V process voltage inputs, but requires external terminals for distribution of 24 V power supply to the field devices. The TU812 Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.
