Modbus RTU Connection Module
for installations with the In-Rail-Bus system
The Modbus RTU Connection Module is used to connect the 24 V supply and the Modbus lines A and B to the In-Rail-Bus DIN rail connector.
The power supply and the Modbus lines are connected to the terminals of the module (screw terminals). The connection to the In-Rail-Bus DIN rail connector is made via the rear spring contacts. All other DRAGO I/O modules are thus pre-wired via the In-Rail Bus with power supply and bus lines.
DIP switches can be used to switch the termination and polarization resistors normally used for RS485 interfaces. An additional line is available for group messages, e.g. for a group error message, as far as this is supported by the I/O modules.
The Modbus RTU connection module can also be used for feed out, especially if further modules are to be connected in separate installations. Additional terminals for the bus lines are provided for this purpose.
