Binary input and binary output functionality is fully programmable. These can be used for a number purposes.
Voltage operated binary inputs allow the device to receive external information from the system or from other
devices.
The binary output relays are used to initiate primary plant switching and provide indications for remote
signaling of important events and states.
Serial Interfaces
The USB interface on the relay fascia enables local communication with a personal computer when using the
Reydisp operating program.
The IP address for all 7SR5 device front ports is 192.168.2.1.
The USB drivers must be installed prior to connection.
A RS485 port on the rear of the device provides remote communications using user selectable protocols.
Ethernet Interfaces
Additional interfaces on the rear of the device provide remote communications using user selectable proto-
cols.
•
Redundant ethernet communication interfaces
•
Redundant and independent protocols to control centers possible (such as IEC 61850)
