Overview
The Carlo Gavazzi DIB01CB2310A is a precision 1-phase current monitoring relay designed for over- and under-current detection in industrial electrical systems. This DIN-rail mounted device combines True RMS AC/DC monitoring with a 1–10A measuring range and selectable trip logic to protect motors, compressors, fans, and other critical loads. The relay features an integrated shunt, simplifying installation and eliminating the need for external current transformers on circuits up to 10 A.
Key Features
- True RMS AC/DC Monitoring: Accurate current measurement on both AC and DC circuits without harmonic distortion errors
- Over/Under Current Selection: DIP-switch configurable operation for overcurrent or undercurrent alarm logic
- 1–10 A Measuring Range: Integrated shunt handles loads up to 10 A directly; larger loads monitored via external current transformer
- SPDT Relay Output: Normally open or normally closed selectable; rated 8 A @ 250 VAC (AC1) or 5 A @ 24 VDC (DC12)
- DIN-Rail Mounting: Compact 22.5 × 99.5 × 80 mm footprint fits standard rail installations
- Built-in Latch and Inhibit Functions: Hold relay output in alarm state; disable operation during maintenance or transitions
- Status LEDs: Visual indication of alarm state and relay output condition
- 115–230 VAC Supply: Selectable via DIP switch for flexible installation
