BRIDGE-BOY : EOT CRANE OVERLOAD PROTECTION ELECTRONICS WITH 1 OR 3 SET-POINTS

Product catalog summary

Overview: The document details the specifications and applications of the SENSY BRIDGE-BOY, an electronic device designed for overload protection in cranes. It is suitable for overhead, container, and gantry cranes, offering cost-effective load limitation and slack cable detection.

Key Features:

Available with 1 or 3 independent set-points for load limitation and slack cable detection.
Adjustments are made via potentiometers, with analogue outputs of 0...10 V and 4...20 mA.
Mountable on a DIN rail (TS 35) and operates on 115 VAC with an internal jumper.

Applications:

Internal monitoring of load cell integrity and fail-safe load limitation electronics.
Overload visualization through a front panel LED lamp and a test button.

Specifications:

Input range: 0.4...2 mV/V with a single strain-gauge input.
Sensor excitation: 10...28 mA (11 V max).
Accuracy: ± 0.5% Full Scale.
Service temperature range: -20 to +60°C; Storage temperature range: -40 to +70°C.
Power supply options: 48-110 VAC or 115-230 VAC.
Relay type: "Form C" activated in a safe situation with a contact rating of 6 A @ 250 VAC.
Adjustable delay: 60 ms to 1 s.
IP rating: IP20.

Technical Drawings: The document includes standard dimensions and technical drawings for both 1 and 3 set-point configurations, revised on 17/05/2018.
