The AI890 analog input module has 8 channels. The module contains intrinsically safe protection components on each channel for connecting process equipment to hazardous areas without the need for additional external equipment.

Each channel can be a current input or a power supply and monitor a two-wire process transmitter. Current input A transmitter for external power supply. The input voltage drop for current inputs is typically 3 V (including PTC). Transmitter power supplies in each channel are capable of delivering a minimum of 15 V/20 mA loop current to power Ex certified process transmitters, limited to 23 mA under overload conditions. All 8 channels are isolated from the ModuleBus and power supply in a group. The power of the input stage is converted from 24 V on the power supply connection.

The TU890 and TU891 compact MTU can be used with this module to connect two wires to process equipment without additional terminals. The TU890 is for explosion-proof applications and the TU 891 is for non-explosion-proof applications.

Characteristics and advantages

• 8 channels for 0… 20 mA or 4… 20 mA, single-ended unipolar input.

• 1 group of 8 channels isolated from the ground.

• Power and monitor explosion-proof certified two-wire transmitters.

• Non-energy storage analog input for external power supply.
