PRODUCT INFORMATION
Product Overview
The General Electric IC660BBA106 is a 6-channel current-source analog input block for the Genius I/O system. The unit interfaces current transmitters to a supervisory controller over the serial Genius bus. Each channel supports current loops measuring 4 to 20 mA or 0 to 25 mA.
The block provides channel-to-channel isolation across all six input circuits to prevent ground loops. It operates from an incoming supply voltage of 93 to 132 VAC or 105 to 145 VDC. Onboard diagnostic capabilities include monitoring for underrange, overrange, high alarm, low alarm, and open wire conditions.
