PDS178 Watchdog Scanner Temperature and Process System

Brand: Precision Digital Corporation
Does not ship to United States

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.
