Technical Specifications

Technical FAQs

What is the difference between the EH3 series and the standard EH2 series?

The EH3 series provides significantly higher execution speeds (0.19 us vs 0.24 us), larger program memory, and improved high-speed counter performance. Additionally, the EH3 supports more advanced motion control instructions and features better EMI/EMC shielding for noisy industrial environments.

Can I expand the I/O capacity of the DVP32EH00R2-L?

Yes. This main unit supports the full range of DVP-EH series expansion modules. You can add digital I/O, analog I/O, temperature measurement modules, and specialized communication cards to a maximum of 512 I/O points.

Is the internal RTC (Real Time Clock) included?

Yes, the DVP32EH00R2-L includes a built-in Real Time Clock as standard. This is critical for applications requiring time-stamping, scheduled operations, or historical data logging.

Engineering & Installation Guide

• Relay Protection: While relay outputs are robust, switching inductive loads (such as solenoids or contactors) can cause contact arcing. For DC loads, install a flyback diode across the load; for AC loads, use an RC snubber circuit to extend the mechanical life of the PLC's internal relays.

• Thermal Management: When mounting the PLC in a control cabinet, ensure at least 50 mm of clearance above and below the unit for natural convection. Avoid installing the unit directly above heat-producing devices like high-power servo drives or transformers.

• Grounding Protocol: To minimize electromagnetic interference (EMI) and ensure stable high-speed counter readings, connect the "S/S" and "FG" terminals to a low-impedance system ground. Use shielded twisted-pair cables for all high-speed signal inputs and RS-485 communication lines.
