In-Rail-Mini-Modbus

In-Rail-Mini Modbus

for installation of small Modbus applications with In-Rail Bus System

Cost-effective and fast solution for small In-Rail-Bus installations.

The In-Rail-Mini Modbus is used to put the supply voltage 24 V DC into the In-Rail-Bus connectors and to connect the Modbus lines A and B. Line E is available for group messages, e.g. for a group error message. DIP switches can be used to connect the usual terminating and polarization resistors for RS 485 interfaces.

The In-Rail-Minis are available for DIN rail heights of 7.5 mm and 15 mm (see order information).
