Topcon Opus A3F and A3S display units

Overview

Description

The Opus A3F and A3S Topcon display units are cost-efficient, rugged operator control panels for use on heavy-duty vehicles and work machines that must operate outdoors in harsh conditions. They are fully equipped with an encoder, three hard and eight soft-function keys, integrated buzzer, RS232 and USB ports, and CAN bus. The A3F (full-featured) unit has analog/digital inputs, digital outputs, Ethernet and video connections for use with a camera to monitor process operations.
