HE670ADC840A 4-20mA Isolated Analog Input Product Specifications and Installation Data 1 DESCRIPTION The 4-20mA Isolated Analog Input module (HE670ADC840) is compatible with GE Fanuc Field Control. It provides eight analog channels with a resolution of 12-bits. Isolation levels are 400VDC (channel-to- channel) and 1,000VDC (channel-to-ground). The module converts the current input signals into digital values, which can be accessed through communications with the Bus Interface Unit. These modules are physically housed in the standard Field Control I/O case and are compatible with a variety of I/O bases providing flexible termination options. NOTE: For HE670ADC840, revision C and higher, hot swap capability is supported.

GO TO SOURCE

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
