The Model SKYD Alarm Unit accepts input signals, and provides absolute or deviation alarm outputs. Absolute alarms are output after comparison of input signals from a single source with one or two setpoints, and deviation alarms are output after comparison of input signals from two sources with two setpoints. Direct or reverse alarm action can be selected for each of the alarm output settings. The front panel is provided with an alarm LED for confirming alarm relay operation (when relay is energized). The JHT200 Handy Terminal* is used for setting Alarm Unit parameters. On the SKYD model with display setter (SKYD- 04), input indication (engineering unit) and alarm settings can be set on the front panel.

*:The adapter for modular jack (E9786WH) is required for connecting the JHT200 Handy Terminal to the Alarm Unit.

The BT200 BRAIN Terminal of YOKOGAWA Electric Corporation can also be connected. (Both 5-pin communication cable: F9182EE and the adapter for modular-jack: E9786WH are required.)
