Adjustable RS-485 serial interface. The integrated interface in the module allows for the connection of devices with an RS-485 interface. The interface operates in accordance with TIA/EIA-485-A, DIN 66259 standards. The connected device can communicate directly with the control system via the used bus coupler. The active communication channel operates independently of the underlying bus system in full duplex mode at speeds of up to 19200 baud. The RS-485 interface ensures high noise immunity through galvanically isolated signals. The shield connection is directly routed to the mounting rail.
