Automate programmable haute performance série DVP64EH00T3 DELTA DVP-EH3

Product Overview

The DVP64EH00T3 (DVP64EH00T3) represents the latest iteration of Delta’s flagship DVP-EH3 high-performance series. This "Base Unit" provides an exceptionally high I/O density with 64 integrated points (32 digital inputs and 32 transistor outputs) within a single modular chassis. As the premier controller in the DVP-E line, the EH3 series is engineered for the most demanding industrial applications, offering specialized hardware for high-speed motion control, large program execution, and complex data handling. Featuring an "H Type" AC input power supply and high-speed transistor outputs, the DVP64EH00T3 is the standard for multi-axis CNC machines, high-speed material handling, and sophisticated automated assembly lines.

Technical Configuration

The hardware of the DVP64EH00T3 is designed for high-speed precision. It features 32 digital inputs and 32 NPN transistor outputs. The transistor stage is optimized for motion control, supporting up to 200 kHz high-speed pulse output across multiple channels, allowing it to drive several servo or stepper axes with sub-millisecond responsiveness. The CPU boasts a massive 30k step program capacity and expanded data registers (12k words), supporting complex arithmetic and multi-layered logic structures. Connectivity is managed through three independent communication ports (RS-232 and dual RS-485), facilitating simultaneous communication with HMIs, variable frequency drives, and SCADA systems via the Modbus protocol.

Technical Specifications

Technical FAQs

What is the difference between the "T2" and "T3" versions of this PLC?

The "T3" designation in the DVP64EH00T3 represents a hardware revision that often includes optimized internal circuitry for better electromagnetic compatibility (EMC) and potentially updated firmware support for newer expansion modules. While backward compatible with "T2" logic, the T3 version ensures the highest reliability for current-generation automation architectures.

Can the 200 kHz outputs be used for interpolation?

The DVP64EH00T3 supports linear and circular interpolation through specialized API instructions in the Delta software. With its 200 kHz pulse output capability, it can execute smooth, coordinated movements between multiple axes, which is essential for specialized cutting or dispensing machines.

How does the "H Type" AC input handle power fluctuations?

The H Type power supply is a wide-range industrial SMPS (Switching Mode Power Supply). It is designed to maintain a stable internal 24 VDC bus even if the AC line voltage fluctuates between 100V and 240V. This prevents CPU resets or I/O flickering in plants with heavy machinery starting and stopping on the same power grid.

Engineering & Installation Guide

• Shielded Wiring for High-Speed I/O: To maintain signal integrity at 200 kHz, all pulse output (PU) and direction (DR) wiring must use shielded twisted-pair (STP) cables. The shield should be grounded at the PLC side to mitigate high-frequency noise from VFDs or large motors that could lead to position loss.

• Transistor Load Protection: Transistor outputs are strictly for DC loads (5-30 VDC). For inductive loads like small DC relays or solenoids, ensure a flyback diode is installed across the load to prevent back-EMF spikes from damaging the PLC's internal transistor array.

• Expansion Bus Management: The DVP64EH00T3 can be expanded to a total of 512 I/O points. When adding high-speed or analog modules to the right side of the CPU, ensure the total power consumption does not exceed the internal power supply's capacity. If it does, an additional DVP-PS series power supply module should be integrated into the rack.
