General Description

The DAT3015-V Voltage to Modbus Converter is a 4-channel input module designed for acquiring DC voltage signals and transmitting them digitally over a Modbus network. It converts the analog voltage input into a precise 16-bit digital format for integration with PLCs, SCADA, and other Modbus master devices.

Each channel supports a full-scale input of –10 to +10 VDC, making the module suitable for monitoring a wide variety of process signals and transducers.

Communication is available over RS-485 using the Modbus RTU protocol, with an option for RS-232 Modbus ASCII format. The DAT3015-V is configured using the free DAT3000–10000 configuration software, downloadable from our website, which provides advanced setup and calibration.
