IC660BBA024

The IC660BBA024 Current Source I/O Block is a 24 to 48 Volts DC rated current source I/O block that belongs to the GE Fanuc Series 90-30 I/O module product line. It helps to connect with devices that offer 4 milliamps to 20 milliamps rated analog signals. Some of the features of this block include 4 inputs and 2 outputs, isolated channels, and factory calibration. Each input on the IC660BBA024 Current Source I/O Block offers a 24 Volts current loop power supply. The output channels also provide two 4 to 20 milliamps rated current loops. All of the input and output circuits offer linear scaling that helps to generate engineering units as well as diagnostic facilities.

The IC660BBA024 Current Source I/O Block measures 22.44 x 8.48 x 9.93 centimeters and weighs 4 pounds. The specifications of the 4 independent inputs are 0.1% of the full-scale reading accuracy at 25 degrees Celsius, 1 microamp of input resolution, 16.6 milliseconds to 400 milliseconds of input conversion time, and 4 to 20 milliamps of current range. The specifications of the 2 output circuits include 6 microamps of output resolution, 4 to 20 milliamps of current range, 6 to 8 milliseconds of output update frequency, and 0.15% of full-scale reading accuracy at 25 degrees Celsius. It uses a voltage to frequency converter to convert the analog readings into digital values. The independent outputs are all electrically common with each other. A 24 to 48 Volts DC version of a Bus switching module can be directly connected to the IC660BBA024 Current Source I/O Block. In order to power up the module, a 24 to 48 Volts DC supply must be connected to the DC+ and DC- terminals.
