DVP04AD-S 4-Channel Analog Input Module 14-Bit DVP-S Series | Delta

The Original New Delta DVP04AD-S is a 4-channel analog input module from the DVP-S Slim Series, designed for high-precision signal acquisition in industrial automation and process control systems. Each channel receives analog voltage or current signals and converts them into 14-bit digital signals. The module connects to Delta DVP-S series PLCs via RS-485 communication and can also be accessed using FROM/TO instructions through the MPU. Its compact DIN-rail-mountable design with pluggable screw terminals simplifies wiring and accelerates installation in space-constrained control cabinets. The DVP04AD-S is suitable for reading signals from temperature, pressure, flow, and level sensors.

⚠️ Important Product Status Note:
This product (DVP04AD-S) has been marked as Obsolete by the manufacturer and is no longer in production. The manufacturer-recommended replacement is the DVP04AD-S2 (enhanced noise immunity version). This product remains a valid spare part for maintaining existing systems. PLC ERA stocks are limited; availability should be confirmed before ordering. For new projects, please consider the recommended replacement model.
