dimension
The AI895 analog input module can be connected directly to a 2-wire transmitter, and with a specific connection, it can also be connected to a 4-wire transmitter without losing HART function. The AI895 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 power and monitor two-wire process transmitters and HART communications. 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.
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 TU891 is for non-explosion-proof applications.
Characteristics and advantages
• 8 channels for 4... 20 mA, single-ended single-pole input.
• HART communication.
• 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.
