The new dRTU-3000 series consist of different remote I/O modules, each with a serial communication interface, using Modbus RTU. The series may include devices with analog and discrete inputs, as well as analog and discrete outputs.
The remote I/O module type dRTU-3018 operates with 8 discrete inputs type "dry contact" via the Modbus RTU communication protocol over a serial interface RS485. The 8 inputs have common ground and are galvanic isolated from the power supply and communication lines. The power supply can be either 230 VAC or 24 VDC (on request).
The module type dRTU-3028 consists of 8 output relays SPDT 5A/250 VAC (5A/30VDC on request). The RS485 communication line and the power supply are galvanic isolated. The power supply can be either 230 VAC or on request – 24 VDC.
