Product Description
IC693APU300 is a high speed single slot counter belonging to the 90-30 series of PLCs. The module can be used where pulse input rates are greater than the PLCs input capability or where a significant percentage of the PLC’s processing capability is required.

The high-speed counter allows direct processing of rapid pulse signals of up to 1 MHz for industrial applications such as material handling, meter proving and velocity measurement. With the direct processing capability, the high-speed counter can detect inputs, count and respond with outputs without the need of communicating with a CPU. It’s configurable to count either up or down, both up and down or to count the difference existing between two variables. The module can be configured to provide either 1 complex counter, 2 identical and complex counters, or 4 identical and independent simple counters. The module comes with 12 positive source inputs with an input voltage range of either 5 V DV or 10 to 30 V DC. Furthermore, you’ll find 4 positive source outputs, internal module diagnostics, and a removable terminal board used during field wiring. The IC694APU300 module provides two modes of operation when used in an RX3i system: Classic and Enhanced. By default, the module operates in classic mode. However, if you desire to use enhanced features, select ‘Enhanced mode’ using the machine edition configuration tool.

Enhanced features include Support for up to 1 MHz input frequency from external devices and up to 2 MHz internal oscillator at clock input 1, support for both 32-bit counters and Z input events, configurable outputs, rollover detection flag and support for firmware updates over the backplane from the RX3i CPU. IC693APU300 also has a windowing feature that allows a user to define a range of counter accumulator values where the strobe is recognized as a valid input. Should the counter accumulator go outside this range, the strobe input is ignored. Since the module is considered an open type equipment, it should be installed into an enclosure with minimal pollution. For wiring connections, use copper wire with a minimum rating of 90 degrees Celsius. If two wires are allowed, then they should be of the same type. Before wiring, replacing modules, batteries, fuses or any other serviceable component, it’s recommended to TURN OFF the power. This is to avert any mishaps that may occur. Moreover, the product should be mounted in an enclosure certified for use in Zone 2, Group IIC, and rated IP54 minimum. During field wiring, shielded cable must be used for all cables connecting to the IC694APU300 High-speed Counter. The shielded cable should possess a high frequency ground within 6 inches of the IC694APU300 module.
