Overview

The Omni16 C1486A-EX Remote Display is a backlit Remote Display suitable for use in hazardous environments. The Omni16C Display once mounted is fully enclosed in an Ex nA enclosure to allow location in the hazardous area.

Configuration

The C1486A-EX accepts 16 inputs. The unit can be configured as either a positive-common or negative common by reversing the LED display boards.

Mechanical

The restricted-breathing enclosure mounts around a panel cut-out which is made to accommodate the C1486A. The C1486A is secured with jacking bars and stud holes are drilled surrounding the cut-out to accommodate the gasketed front cover. Once the Remote Display is mounted into the panel cut-out the gasketed rear enclosure is then bolted over the Remote Display from behind the panel ensuring an airtight seal on the front and rear of the panel.
