GE IC670GBI002 Bus Interface Unit: Your Field I/O Workhorse
This GE Fanuc bus interface unit keeps refineries and assembly lines humming by bridging field devices like sensors and actuators with Series 90/70 PLCs. Honestly, it’s not flashy – but when your conveyor belt needs constant comms between photoelectric sensors and the main controller, this thing just works without drama. Seen it deployed everywhere from Midwest automotive plants to Gulf Coast chemical facilities where downtime means six-figure losses.
| Brand | GE Fanuc (now part of Emerson) |
| Voltage Range | 18-30 VDC (accepts 115V AC/125V DC nominal) |
| Power Draw | 16.8W typical – runs cooler than most competitors |
| Bus Current | 1.4A output – handles 8-10 I/O modules comfortably |
| Dimensions | 122mm H × 76mm W × 114mm D (fits tight panels) |
| Weight | 0.45 kg – won’t stress mounting rails |
You’ll typically find this unit anchoring GE Fanuc Series 90-30/70 systems – think FBM203 analog inputs feeding into this bus interface at a paper mill, or FBM217 thermocouple modules in a food processing plant. Last month a client in Ohio replaced failing third-party interfaces with IC670GBI002s across their bottling line; their maintenance lead texted me saying “finally stopped those intermittent comms dropouts during high-humidity shifts.” We handle all the common siblings too – VMIVME-7807 for legacy VME systems, IS230SRTDH2A for Mark VIe turbine controls, and yes, even those tricky IC698CPE010 CPUs that keep old Chrysler plants running.
What makes this unit worth the premium? For starters, that 1.4A bus current means you can daisy-chain more modules without external power – saved a wastewater treatment plant $2k in extra PSUs last year. The dual-voltage design (AC/DC input) is clutch when retrofitting old systems; I’ve seen technicians plug these straight into 24VDC control panels without rewiring. And while GE doesn’t shout about it, the conformal coating handles 95% humidity without issues – personally installed a batch in a Louisiana sugar refinery where other interfaces corroded in months. Compatibility’s solid with legacy 90-30 racks but watch the firmware version; had a headache last quarter when someone used v1.2 firmware with pre-2005 I/O bases.
