GE IC660BBA105N1

Product Name:​ GE Fanuc IC660BBA105N1 – Genius I/O Current-Source Analog 6-Output Block
Product Introduction:​ The IC660BBA105 is a current-source analog output block in the GE Fanuc Series 90-30 PLC family and the Genius I/O product line. It provides six electrically identical, isolated 4–20 mA current sourcing outputs for driving field devices. It can be powered by either 115 VAC or 125 VDC, and supplies isolated power to the current loops directly — no external loop power supply is required. A variant (IC660BBA025) supports 24/248 VDC power.
