The GE IC693APU300 High-Speed Counter Module is a single-slot counter module from GE Fanuc. It is suitable to use in applications that require high levels of processing power and capabilities from the programmable logic controllers or PLCs that handle them. The main benefit of this counter module is that it is capable of processing rapid signal pulses that are rated at up to 80 kiloHertz of frequency. This high-speed counter module can sense inputs and outputs as well as count input and output responses without communicating with the CPU. The IC693APU300 High-Speed Counter Module can count both up and down and it can count the difference between 2 changing values. In order to indicate the operating status and configuration parameter’s status, the module has 2 green LEDs on its top face.

The IC693APU300 High-Speed Counter Module can be arranged to have 4 identical independent simple counters, 1 complex counter, and 2 identical independent complex counters. Some of the features of this high-speed counter module include counts per time-based register for each counter, a removable terminal board for field wiring, and internal module diagnostics. The power for the module is drawn from the 5 Volts DC rated Bus of the PLC backplane. The IC693APU300 High-Speed Counter Module can be installed in any Series 90-30 baseplate. Never install this module in an enclosure that is only accessible with the use of tools. This module cannot be removed or replaced without shutting down the PLC properly. It can be configured by using the Logicmaster 90-30/20, Hand-Held Programmer, Logic Developer-PLC, or VersaPro software. This module can be used in industrial applications which have pulse input rates that exceed the input capability of the PLC such as meter proving, material handling, velocity measurement, motion control, and turbine flow meter applications.
