GE Fanuc Field Control® Distributed I/O and Control System

Field Control is a family of versatile, truly modular I/O products, suitable for use in a wide range of

control system architectures.

Field Control I/O Modules are small and rugged. They provide easily-configurable discrete and

analog I/O interfaces which may also include local intelligence for signal processing.

I/O Terminal Blocks provide universal field wiring terminals for two I/O modules, allowing I/O

module types to be mixed on the same I/O Terminal Block. The I/O Terminal block is mounted on

a DIN rail. The DIN rail, which is an integral part of the grounding system, must be mounted to a

panel.

As many as eight Field Control I/O modules (four I/O terminal blocks) can be connected to one

Bus Interface Unit. Together, they make up a Field Control “station” Bus Interface Units are

available for different types of busses, such as Genius, Profibus, and FIP.

The Bus Interface Unit provides the I/O scanning, diagnostics, and communications capabilities

needed to link the I/O modules to the control system. In addition, the Bus Interface Unit may

provide (and store) configurable characteristics for I/O modules, such as fault reporting, output

defaults, analog range selection, and analog scaling.

I/O Modules

Field Control I/O modules are small rugged components with sturdy aluminum housings.

Modules are approximately 3.25 inches (8.2 cm) high x 2 inches (5.25 cm) wide. They are 2.90

inches (7.3 cm) deep (not including the portion that extends into the I/O Terminal Block).

Both discrete and analog conventional input and output modules are available. In addition,

intelligent modules, which perform more advanced functions, are also available. Examples of

intelligent modules are the Micro Field Processor, the 16-point Grouped Analog Input module

(IC670ALG240), the Thermocouple Input module (IC670ALG630), and the RTD Input module

(IC670ALG620).

LEDs

I/O Module LEDs are easily visible through the transparent central portion of the label. All

modules have an LED that indicates the presence of module power. Discrete modules also have

individual circuit LEDs that show the on/off status of each input or output circuit.
