The 140EHC20200 high-speed counter module belongs to Schneider Electric's Modicon Quantum automation platform. This standard-format module offers two independent counting channels. Each channel handles incremental or quadrature input signals at frequencies up to 500,000 Hz. The module includes four discrete FET outputs for direct control actions. Furthermore, it supports both local and remote rack installations. This counter module suits applications like positioning, length measurement, and speed monitoring.
The 140EHC20200 provides two counting channels with flexible input types. Users can select incremental or quadrature modes per channel. The counting frequency reaches 500 kHz for high-speed pulse trains. Data formats include 32-bit (2,147,483,647 decimal) and 16-bit (65,535 decimal) options. The module requires 6 input words and 6 output words for addressing. Discrete inputs accept voltages below 30V DC with a 10 kOhm input resistance. Operating thresholds vary by mode: single-ended 24V DC, 12V DC, or 5V DC, plus differential mode. Specifically, the differential mode threshold starts at 1.8V for reliable noise immunity.
The module features four discrete FET outputs rated at 0.5A each. Output voltage drop measures below 0.4V in the on state. Leakage current stays under 0.4 mA when off. Protection includes 36V transorb devices for output transient suppression. Short-circuit protection uses a 2.5A fuse on each output. Isolation between channels and the bus reaches 1780Vrms for 60 seconds. Additionally, the module detects loss of output field power as a fault condition.
Bus current consumption is 650 mA from the Quantum backplane. External power supply ranges from 19.2 to 30V DC. Total current consumption with external power reaches 1050 mA maximum. Power dissipation calculates as 4 + (0.4 x total module load current) in watts. This efficient design minimizes heat generation within the rack.
The 140EHC20200 uses a standard module format for Quantum racks. Package dimensions are 5.0 cm height, 17.0 cm width, and 32.0 cm length. The unit weighs 444 grams (15.7 ounces). Operating temperature ranges from 0 to 60°C (32 to 140°F). Storage temperature spans -40 to 85°C (-40 to 185°F). Relative humidity tolerance reaches 95% without condensation. Operating altitude extends to 5000 meters (16,404 feet). The module resists electrostatic discharge per IEC 801-2 at 4kV contact and 8kV air. Electromagnetic field immunity meets IEC 801-3 at 10V/m.
First, power down the Quantum rack before inserting the 140EHC20200. Slide the module into the designated slot until fully seated. Next, connect field wiring to the front connector following the terminal assignments. For quadrature signals, wire both A and B phases to the corresponding input terminals. Use shielded twisted-pair cables to preserve signal integrity at high frequencies. Additionally, connect the external 24V DC power supply to the module's power terminals. After wiring, apply power and observe the two channel status LEDs. Finally, configure the counter parameters within the Unity Pro or Concept software environment.

1. Q: What types of encoders work with the 140EHC20200?
A: This module accepts both incremental and quadrature encoders. Specifically, it handles single-ended or differential signals up to 500 kHz.
2. Q: Can I use both channels independently?
A: Yes, each channel operates independently. You can configure one channel in incremental mode and the other in quadrature mode simultaneously.
3. Q: How do I reset the counter value during operation?
A: The 140EHC20200 supports software resets via the input words. Additionally, you can configure the FET outputs to trigger resets based on external events.
4. Q: Does this module work in remote racks?
A: Yes, the 140EHC20200 supports local, remote, and distributed rack installations. This flexibility simplifies system layout planning.
5. Q: What happens if the external power supply fails?
A: The module detects loss of output field power as a fault. The status LEDs indicate this condition, and the system logic can respond accordingly.
