DVP40EH00T2 DELTA DVP-EH3 Series High-Performance PLC

Product Overview

The DVP40EH00T2 (DVP40EH00T2) is a high-performance main processing unit from Delta's flagship DVP-EH3 series. Positioned as the high-end choice within the DVP-E line, the EH3 series offers superior execution speed, larger data registers, and advanced motion control capabilities compared to standard PLCs. This "Base Unit" provides a robust density of 40 I/O points (24 digital inputs and 16 transistor outputs) in a single modular chassis. Optimized for complex industrial machinery such as high-speed labeling systems, precise welding robots, and automated assembly lines, the DVP40EH00T2 features an "H Type" AC input power supply and high-speed transistor outputs designed for rapid switching and precision pulse-train positioning.

Technical Configuration

The DVP40EH00T2 hardware architecture is engineered for demanding real-time applications. It features 24 high-speed digital inputs and 16 NPN transistor outputs. The transistor stage is specifically designed for motion control, supporting up to 4 channels of 200 kHz pulse output for controlling multiple servo or stepper axes simultaneously. The CPU boasts a large program capacity of 30k steps and an expanded register set (12k words), allowing for complex data processing and recipe management. Additionally, the unit provides three integrated communication ports (RS-232 and dual RS-485) that support the Modbus protocol, ensuring seamless connectivity with HMIs, VFDs, and sensors.

Technical FAQs

What is the primary benefit of the EH3 series over the previous EH2 models?

The EH3 series, including the DVP40EH00T2, offers a significant leap in processing power and motion control. It supports higher pulse output frequencies (200 kHz vs 100 kHz) and faster instruction execution (0.24 us). This allows for higher precision in positioning and the ability to handle more complex logic without increasing the PLC scan time.

Can the transistor outputs handle AC loads?

No. Transistor outputs (T2) are designed exclusively for DC loads, typically 5 to 30 VDC. They are ideal for high-speed switching and driving servo inputs. If your application requires switching AC loads (e.g., 220 VAC solenoids), you must use an external interposing relay between the PLC output and the load.

How many expansion modules can I add to the DVP40EH00T2?

The DVP-EH3 series supports up to 512 total I/O points. You can add a variety of right-side expansion modules, including digital I/O, analog I/O, temperature controllers, and specialized communication modules, allowing the DVP40EH00T2 to scale with your system's complexity.

Engineering & Installation Guide

• Pulse Train Integrity: When using the 200 kHz high-speed outputs for servo control, it is essential to use shielded twisted-pair (STP) cabling. Ground the shield at the PLC’s "G" terminal only to prevent ground loops while ensuring that electromagnetic interference (EMI) does not cause "false pulses" that lead to positioning errors.

• Power Supply Stability: The "H Type" AC input is rated for 100-240 VAC. To protect the high-speed CPU from line surges, it is highly recommended to install a surge protector or an isolation transformer on the power line. Ensure the PLC's ground terminal is connected to a dedicated, low-impedance earth ground.

• Mounting and Heat Management: Install the PLC on a standard 35 mm DIN rail. Since the EH3 handles high-speed signals, it can generate internal heat. Maintain at least 50 mm of vertical clearance above and below the unit for natural convection. Avoid mounting the PLC in the same vertical plane as high-heat devices like braking resistors.
