DELTA DVP48EH00T2 DVP-EH2 Series PLC Main Processing Unit

Product Overview

The DVP48EH00T2 (DVP48EH00T2) is a high-performance 48-point main processing unit from Delta's DVP-EH2 series. Engineered for complex machine automation and high-speed multi-axis motion, this PLC features a robust, high-density I/O grid and dual-core logic execution capabilities. It is a cornerstone for intensive applications such as high-speed sheet metal stamping, bottling lines, logistics sorting, and textile manufacturing. By offering hardware-driven positioning registers and rapid digital isolation, the DVP48EH00T2 ensures process repeatability and high-speed execution in demanding industrial environments.

Lifecycle Note: Hardware Migration

The legacy DVP48EH00T2 has been officially superseded by the DVP48EH00T3. The DVP48EH00T3 is a direct functional replacement, maintaining identical physical terminal dimensions, layout, and voltage constraints. The updated T3 version provides enhanced processing speeds, increased data register capacity, and improved high-speed counter filtering to better manage modern industrial electrical noise.

Technical Configuration

The DVP48EH00T2 provides a high-density I/O configuration distributed across 24 digital inputs (24 VDC) and 24 transistor execution channels. Its processing core supports concurrent digital execution and precision high-speed pulse tracking. With integrated hardware counters and pulse outputs capable of 200 kHz, this unit is capable of commanding multi-axis servo systems natively. The NPN transistor outputs deliver wear-free, microsecond-level response times, perfect for high-frequency PWM or rapid relay cycling.

Technical Specifications

FAQs

Is the DVP48EH00T2 software compatible with the T3 replacement?

Yes. Use Delta's WPLSoft or ISPSoft suites. When migrating, open the source project, update the target hardware type to "EH3" in the system configuration menu, and recompile before downloading.

What are the limits of the integrated NPN transistor outputs?

The outputs are rated for a peak switching voltage of 30 VDC and a continuous current draw of 0.5 A per channel. Always install an external freewheeling diode across DC inductive loads (solenoids, coils) to protect internal optocouplers from voltage spikes.

How do the RS-232 and RS-485 ports function?

These ports operate independently. The RS-232 port is typically used for local programming or HMI connections, while the RS-485 port supports Modbus master/slave protocols, allowing the PLC to monitor VFDs or temperature controllers concurrently.

Field Commissioning & Safety Guidelines

• Noise Mitigation: High-speed 200 kHz encoder lines and pulse-train outputs must be routed through continuous twisted-pair shielded cables. Ground the shields strictly at a single panel instrumentation grounding bar, and keep these low-voltage lines at least 150 mm away from high-current AC motor leads or VFD cables.

• Thermal Management: Mount the unit horizontally on a 35 mm DIN rail. Ensure a minimum clearance of 50 mm above and below the chassis to facilitate convective cooling. Do not exceed an ambient panel temperature of 55 deg C.

• Power Protection: Connect the 100-240 VAC supply via a slow-blow fuse block to protect the internal power regulation circuitry. The main panel earth must be bonded directly to the PLC's ground terminal using a low-impedance copper conductor to mitigate common-mode noise.
