General Electric IC600BF808 Series Six 8-Point Interrupt Input Module

Description

The General Electric IC600BF808 is an 8-point interrupt input module developed for the GE Series Six programmable logic controller platform. It connects high-speed field devices directly to the control architecture, enabling the central processing unit to react to external process events without waiting for the completion of a normal ladder program scan. When an active signal transition is detected at an input terminal, the module alerts the processor to suspend normal program execution and immediately execute a designated user interrupt subroutine.

Engineered for high-demand industrial automation tasks, the IC600BF808 incorporates fixed 300 microsecond input filtering to suppress electrical contact bounce and line noise while preserving rapid reaction capabilities. The module hardware includes a dedicated printed circuit board assembly paired with a front faceplate that slides into standard Series Six chassis slots.

Features

• Provides 8 high-speed discrete interrupt input channels rated for 10 to 30 VDC operation.
• Fast hardware input filtering rated at 300 microseconds for reliable high-speed edge detection.
• Built-in priority arbitration that automatically services the lowest numbered interrupt first during simultaneous trigger events.
• Supported across General Electric Series Six Model 60 and Model 600 CPU configurations.
• Flexible installation options in either a CPU I/O station or a local I/O station rack.
• Standard board-level assembly supplied complete with front faceplate.

Technical Specifications

Installation and System Configuration

The IC600BF808 can be deployed across local I/O stations or directly within the CPU I/O station of a Series Six architecture. When integrated into an I/O chain, any intermediate I/O transmitter modules pass the active interrupt signals through to the CPU continuously to avoid processing delays.

In CPU memory mapping, interrupt input data assignments depend on the chain configuration. When placed on the Main I/O chain, the module's 8 inputs are assigned to status table bits I1001 through I1008. If placed on an Auxiliary I/O chain, the inputs correspond to status table bits AI1001 through AI1008. When simultaneous input events occur across multiple channels on the module, hardware logic prioritizes execution so that the lowest numbered input routine is handled before higher-numbered channels.
