Operation
The SEC 3100 ISO RS-485 Repeater Module is used in conjunction with the SEC 3100 transmitters and
the SEC 3500 HMI Operator Interface or other MODBUS RS-485 data highway systems. The SEC 3100
ISO RS-485 Repeater Module is used to extend the distance of the RS-485 network and increase the
number of devices on the RS-485 network. The SEC 3100 ISO RS-485 Repeater Module provides 1500
volt isolation bidirectional data flow and transient suppression on the RS-485 data lines. An SEC 3100
ISO RS-485 Repeater Module should be installed for every 1000 feet of data highway cable or 32 network
devices. The SEC 3100 ISO RS-485 Repeater Module is powered by 24 VDC and wired in line with the
SEC RS-485 network devices. A typical wiring diagram is shown below:
