IC660BBA024

Product Description

IC660BBA024 is an I/O Block from the GE Fanuc Genius I/O Series. The block has a rated voltage of 24/48 VDC. IC660BBA024 is mainly used as an interface controller with devices that accept 4mA to 20mA analogue signal. There are four inputs and two outputs. It provides isolated power to all six circuits, thus eliminating the need to separate power from 4mA to 20mA devices. It also lets the user select linear scaling values for each circuit independently of the others using those values. A handheld monitor enables viewing output as engineering units.

To translate analog signals to digital signals, the input channels use voltage to frequency converters and counters. The block converts the value to engineering units before it is sent to the central processing unit.

Each one of the four independent inputs has a 24V current loop power supply that is capable of providing 25mA of current. Input channels are each isolated from other circuits within the block. Input accuracy is 0.1%. To provide the correct combination of noise rejection and input resolution, input conversion is selected. Conversion times are programmable from 16mS to 400mS. Resolution increases as the conversion time extends. Input resolution is 1µA for 200mS conversion time.

The two independent IC660BBA024 output circuits possess the same electrical configuration but are isolated from all other circuits on the block. The block provides power for the outputs’ current loops.

The two output channels make use of a dual 12-bit digital to analog converter. Each channel individually controls the currents from 0mA to 24mA. Output accuracy is 0.15% at 25C, while output resolution is 6µa.

When installing a Current-Source Analog I/O Block into a redundant bus cable system, take advantage of the block’s dedicated digital output to pair it with a 24/48 VDC Bus Switching Module. IC660BBA024 block software is configurable regardless of whether you use bus switching or not. IC660BBA024 block does not need user calibration since Genius series block diagnostics come standard.

The user may opt to remove the electronics assembly and replace it with a compatible model. IC660BBA024 electronics assembly and the terminal assembly are separate pieces of the same block. The user can substitute the electronics without disturbing field wiring.

IC660BBA024 current-source Analog Block design makes upgrading and repair easier. Simply unscrew the holding screw at the top and bottom of the electronics assembly. Use a block puller tool to pull off the terminal assembly, thereby completing the uninstallation.

Point to note: IC660BBA024 is almost identical to IC660BBA104, the only difference being the power supply. IC660BBA104 uses a 115 VAC power supply.
