DUC01/PUC01 is a voltage monitoring relay produced by Schneider Electric. It can monitor AC/DC overvoltage or undervoltage. It has 1 or 2 8A SPDT relay output and delay, latching or inhibit functions.
The document describes the CARLO GAVAZZI DUCO1 and PUCO1, which are precise True RMS AC/DC over+under, over+over, or under+under voltage monitoring relays. These devices allow users to select measuring ranges from 2 to 500 V via DIP-switches and feature adjustable voltage levels, hysteresis, and delay functions ranging from 0.1 to 30 seconds.
The manual details the technical specifications for both DIN-rail (DUCO1) and plug-in module (PUCO1) versions, including contact ratings, environmental conditions, and wiring diagrams. It explains various operating modes such as latching and inhibit functions, providing examples of how to configure the relays for different alarm scenarios.
| Measuring ranges | 2 to 500 V AC/DC |
|---|---|
| Output relay rating (Resistive) | 8 A @ 250 VAC |
| Operating temperature | -20 to 60°C (DUCO1) |
| Delay function range | 0.1 to 30 s |
| Housing dimensions (DIN-rail) | 45 x 80 x 99.5 mm |
The document describes Types DUCO1 and PUCO1.
The measuring range is selected using DIP-switches.
The contacts can handle 8 A at 250 VAC or 5A at 24VDC.
