The OptiLogic™ Remote Terminal Unit (RTU) is modular in design. It allows you to plug together any combination of analog and digital inputs and outputs that will fit in the available slots. The card cage base snaps onto a standard DIN rail for back panel mounting. If an operator panel is required, the base snaps onto any variety of available OptiLogic™ operator panels, which can in turn be panel mounted. The Ethernet connection provides a 10BaseT connection to the network.

A system built with OptiLogic™ RTUs allows you to monitor and control equipment and systems spread throughout a building. A PC with a standard Ethernet connection can serve as the central controller. Input data, output control and operator panel operation are only a millisecond response away.

If you are a software professional, you can easily develop your own software to run on the PC and interface OptiLogic™ RTUs. A Software Development Kit is available for such purposes.

OptiLogic Base Description

The figure above shows an OptiLogic™ Ethernet RTU base. The particular base shown is a 8 slot base. (Bases with different numbers of slots are available and have the same basic features.) An OptiLogic™ Ethernet RTU base consists of a card cage containing an OptiLogic™ motherboard. The base unit has a built in Ethernet port, as well as an RS232 port. The OptiLogic™ Base mounts by snapping onto a standard DIN rail, or by snapping onto the DIN rail built into OptiLogic™ operator panels. When attached to an OptiLogic™ operator panel, the complete assembly can then be panel mounted. I/O and specialty modules plug into the available slots in the OptiLogic™ base.
