DVP32EH00T2-L DELTA DVP-EH3 Series High-Performance PLC

Product Overview

The DVP32EH00T2-L (DVP32EH00T2L) is a high-speed main processing unit from Delta's premier DVP-EH3 series. This "Base Unit" provides 32 integrated I/O points (16 digital inputs and 16 transistor outputs) in a high-density, modular chassis. As the flagship of the DVP-E line, the EH3 series is specifically engineered for high-end industrial applications that demand rapid execution speeds and precision motion control. The "L" suffix typically denotes a specialized configuration or optimized internal hardware within the EH3 family, making it an ideal controller for high-speed labeling, automated assembly lines, and multi-axis positioning systems.

Technical Configuration

The DVP32EH00T2-L hardware is designed for maximum throughput. It features 16 high-speed digital inputs and 16 NPN transistor outputs. The transistor stage is a key feature for motion control, as it supports high-speed pulse-train output (up to 200 kHz) for direct interfacing with servo and stepper drives. The CPU architecture provides a massive 30k step program capacity and 12k words of data registers, allowing for the storage of complex motion profiles and machine recipes. For connectivity, the unit includes standard RS-232 and RS-485 ports, supporting the Modbus protocol for seamless communication with HMIs and field devices.

Technical FAQs

What is the benefit of the EH3 series compared to the EH2 series?

The EH3 series provides a significant boost in performance, featuring faster instruction execution (0.24 $\mu s$ vs. 0.35 $\mu s$) and enhanced high-speed pulse processing. While EH2 models generally peak at 100 kHz, the EH3 can handle pulse outputs up to 200 kHz, allowing for higher precision and faster cycle times in motion control applications.

Can this PLC be used to switch 220V AC solenoid valves?

No. Because the DVP32EH00T2-L features transistor outputs, it is strictly for DC loads (typically 5–30 VDC). To control AC loads, you must use an external interposing relay or opto-coupler between the PLC output and the solenoid valve.

Is the "L" version compatible with standard EH3 expansion modules?

Yes. The DVP32EH00T2-L maintains the standard DVP-EH expansion bus. You can add a variety of right-side expansion modules, including analog I/O, temperature measurement (PT/TC), and additional digital I/O points, up to a maximum system capacity of 512 points.

Engineering & Installation Guide

• Pulse Train Wiring: When utilizing the 200 kHz high-speed pulse outputs for servo positioning, always use shielded twisted-pair (STP) cabling. This is critical to prevent electromagnetic interference (EMI) from inducing "noise pulses" that could cause position drift or erratic motor behavior.

• Power Supply Integrity: The "H Type" AC input is designed for universal 100–240 VAC power. To protect the high-speed CPU from line transients, it is recommended to use a line filter and a dedicated circuit breaker. Ensure the ground (G) terminal is connected to a clean, low-impedance earth ground.

• Thermal Considerations: When mounting the PLC on a 35 mm DIN rail, ensure a minimum vertical clearance of 50 mm above and below the unit. The high-speed processing of the EH3 generates more heat than standard PLCs; proper airflow is essential to prevent thermal derating of the internal components.
