Omron's C500-CT021 high-speed counter unit provides efficient counting capabilities. This module accommodates a total of two counters. It supports maximum input frequencies reaching up to 500 kHz, ensuring swift data processing. The response time is adequately fast at a maximum of 0.5 ms, making it suitable for applications that require quick counting. Users can benefit from two digital inputs along with two outputs.
Regarding output specifics, the driver type is selectable as an open collector, compatible with both NPN and PNP outputs. The device functions effectively within an operating voltage range of 12 to 24 volts, specifically from 10.2 to 26.4 volts. At the upper voltage limit of 26.4 VDC, it can manage a maximum current of 30 mA under PNP output conditions without any load current.
The switching capacity can vary from 46 mA at 10.2 volts to a peak of 100 mA at 26.4 volts, with an overall maximum rating of 200 mA common. A minimal switching current of 5 mA is required for operation. Notably, the units experience an ON or OFF output delay with a maximum duration of 100 µs each. The leakage current is low, capped at 0.1 mA, while the residual voltage does not exceed 1.5 volts.
It is important to consider that this high-speed counter does not contain short circuit protection. For mounting, the device is designed for panel installation, making it convenient for integration into existing systems.
