DinBox RTU M4: Cost effective, all-in-one, IEC60870-5-104/Modbus Remote Terminal Unit

The DinBox RTU M4 is conceived for integrating Modbus RTU & TCP devices in a SCADA IEC 60870-5-104 environment. The RTU offers mobile communication (LTE Cat. 1 & GPRS), Ethernet routing, RS-485 Modbus RTU, Ethernet Modbus TCP, 8 digital inputs, 2 digital outputs & 2 analog inputs. It is AC powered with a wide range 85-265 Vac power supply but can also be powered 12-24V dc. It is housed in a DINrail case and has has a supercap 'last gasp' allowing the RTU to send messages to the Master for 30 seconds.

The RTU acts as a IEC 60870-5-104 Slave device to the SCADA IEC 60870-5-104 Master, and as Modbus Client (Modbus TCP) or Master (Modbus RTU) and converts the Modbus registers & coils to the IEC 60870-5-104 objects.
