Product Description
Crouzet 84872151 monitoring relay is designed for industrial and automation applications requiring reliable voltage monitoring. This single-phase relay monitors undervoltage conditions within a range of 20 to 80 VAC/VDC, providing precise switching control via a Single-Pole Double-Throw (SPDT) contact configuration. It is mounted easily on standard DIN rails, making it suitable for compact electrical panels.
This model supports control relay functions with selectable memory and adjustable time delays, enabling flexible undervoltage monitoring with high reliability. It operates accurately at 50 Hz, 60 Hz, or DC voltage inputs and uses true RMS measurement to ensure precision.
The relay supports both 24V and 48V AC supply voltages as well as DC supply from 24 to 48V. It allows switching voltages of up to 250V AC/DC with a contact current rating of 5A, suitable for various industrial switching tasks. The compact dimensions (17.5mm width, 69mm length, 92.6mm height) contribute to space-saving control cabinet integration.
The device features an LED status indicator for real-time operation feedback and maintains stable performance between minimum and maximum operating temperatures of +50°C and 50°C. The robust IP30 and IP20 protection ratings ensure durability in typical industrial environments.
Supports undervoltage monitoring with time delay settings. True RMS voltage measurement for accuracy. Compact DIN rail mount design to fit standard electrical enclosures. Wide compatibility with AC and DC supply voltages.
