Annunciators & Scanners Switch

Annunciators & Scanners
Precision Digital’s annunciators and scanners feature alarm and monitoring capabilities for all of your process variables. Annunciators accept up to 8 signals from relays, float switches, digital outputs, and many other discrete (on/off) signal sources. Scanners can accept up to 8 analog inputs and switch between them to another devices such as a digital panel meter, controller, or PLC. One of the most common application for our scanners is bearing temperature monitoring and alarming. They can both be programmed for many common ISA alarm sequences including first out indication and provide alarm indication through front panel LEDs and a build in 85 dB horn. Custom printed message labels can be included with your order at no additional charge.
