CRANE-BOY-Exd CRANE-BOYP-Exd : CRANE OVERLOAD PROTECTION ELECTRONICS (explosion-proof)

Product catalog summary

Overview: The CRANE-BOY-Exd and CRANE-BOYP-Exd are explosion-proof overload protection systems designed for use in hazardous areas on various types of cranes, including overhead, container, gantry, and BOP cranes. These systems are certified for IIB group applications and are also available for IIC group.

Key Features:

Easy and intuitive calibration with a display for hoisted load and input signal.
Internal monitoring system for load cell integrity and load limitation electronics, ensuring fail-safe operation.
Equipped with Zener barriers for connection to Ex i certified load cells, with options available without Zener barriers for Ex d certified load pins.

Applications:

Overload protection and slack rope detection in hazardous areas.
Internal survey system for load cell and electronics with a fail-safe mechanism.
Test button for system functionality checks and a secret code to prevent unauthorized programming.
Intelligent filter for quick reaction to overloads, ignoring transient non-significant overloads.

Specifications:

Load limiter for single load cell with input range of ±24 mVDC / ±240 mVDC or 20 mA (-2 to +26 mA).
Sensor excitation at 10 VDC @ 125 mA max or 24 VDC ± 5% @ 50 mA max.
5-digit display with 0.1% full-scale accuracy and a 16-bit A/D converter with up to 20 readings per second.
Service temperature range from 0 to +50°C and storage temperature range from -40 to +60°C.
Power supply options include 85-250 VAC, 50/60 Hz or 11-36 VDC, 24 VAC.
Equipped with three "Form A" potential-free relays with a contact rating of 3 A @ 250 VAC / 30 VDC.
IP65 rating for dust and water protection.
