The IC660TBA025 is a 24/48V DC current source analog output block designed for use within GE Fanuc's Genius I/O system. As part of the terminal assembly components, this modular input-output module provides seamless connectivity for field wiring and permanent configurations. With six output ports capable of supplying 4 to 20 milliamperes, the IC660TBA025 delivers consistent power without differentiation between output levels. It boasts an accuracy of 0.15% at 25°C, with a fine resolution of 6 microamperes. This device features flexibility for user configurations, including the ability to operate in Bus Switching Mode when integrated into a redundant bus system. Users can also set a default mode and initiate output feedback checks, while options are available to override CPU redundancy and scale circuits to engineering units. The IC660TBA025 includes diagnostic capabilities for monitoring output feedback, ensuring that any dips below 1.5 milliamperes or range violations are promptly addressed. Compatible with PCIM and QBIM modules of the Genius Bus Controllers, the block operates on a power supply range of 18 to 56 volts DC, with a maximum current output of 250 milliamperes.
