PDS178 Watchdog Scanner Temperature and Process SystemBrand: Precision Digital Corporation
The PDS178 Watchdog Temperature Scanning & Alarming System brings together a popular combination of Precision Digital products: the Trident meter, the Minimux II scanner, and the PDA2821 NEMA 4X enclosure.
The scanner automatically switches between up to eight input signals: 4-20 ma, ±10 V, TC, or RTD and sends them to the Trident meter for display.
Signal switching is done via DPST reed relays.
The Watchdog can be used in a variety of temperature and process monitoring applications.
A very common application for this system is to monitor bearing temperatures.
The Trident meter included with this system is available with standard 0.56" - 14.2 mm high LED digits or large 1.2" / 30.5 mm high LEDs.Features
