Detailed Technical Analysis

This analog input base provides termination for up to sixteen field current or voltage signals. It connects to the analog input module via a ribbon cable assembly. The base includes loop power distribution for 2-wire 4-20mA transmitters. You select input ranges using jumper blocks on the base plate.

Now let us examine its power distribution features. This base supplies 24V DC loop power to connected transmitters. Each channel includes a current limiting resistor for protection. The base draws 200 milliamps from an external 24V DC supply. Sixteen screw terminal blocks accept field wiring from sensors and transmitters.

This analog base weighs 0.6 kilograms for stable DIN rail mounting. A single green LED indicates that loop power is present. The base contains no batteries or capacitors for energy storage. Two ribbon cable headers connect to the analog input module above. The wide temperature range suits harsh industrial environments.

Installation and Wiring Guidelines

You mount this base on a standard DIN rail in your control cabinet. Connect the 24V DC loop power supply to the designated terminals. Wire each field transmitter to its designated screw terminal pair. Attach the ribbon cable from the base to the analog input module.

Select the input range for each channel using the jumper blocks. Use shielded twisted-pair cables for all analog signal wiring. Ground the shield only at the base end for noise reduction. Always power down the system before connecting or disconnecting the ribbon cable.

Practical Applications

Engineers use this analog base for INFI 90 system expansion and repair. It organizes field wiring for analog input signals. This component also works in legacy DCS retrofit projects. Its 16 channels suit medium to large process monitoring applications.

Summary of Features

To conclude, this analog input base provides 16 channels with selectable input ranges. It weighs 0.6 kilograms and includes loop power distribution. Choose ABB Bailey PHBAIN2000C100 for reliable analog signal termination in INFI 90 systems.
