Simultaneous Isolated RS485 and RS232 Outputs

Allows flexibility in SCADA Installations where both RS-485 and RS-232 instruments need to be interfaced without adding extra converters or serial splitters.  The RS485 and RS232 ports are wired OR’ed. Isolated Outputs prevent ground loops.

RS232 / RS485 Connections on Terminal Blocks

Terminal Block connections allow simple solderless field wiring by field and shop staff and allow the use of industrial cable and wire gauges from 12-30 AWG.

USB Input & LOI Override Function

The USB LOI override function allows dedicated access to the RS-485 multi-drop bus when the USB is connected. This allows a Technician maintenance access to the connected RS-485 devices without disconnecting field wiring. The USB connection also allows technicians to perform maintenance tasks using modern laptops which lack physical serial (RS-232) Ports.
