Description
The GL7101 is designed for use in earth leakage circuit interrupters for operation directly off the AC line in breakers. It contains pre-regulator, main regulator, subsequent(after) regulator, differential amplifier, level comparator, and latch circuit. The input in the differential amplifier is connected to the secondary node of zero current transformer. The level comparator generates high level when earth leakage current is greater than a certain level.
Features
The GL7101 Module provides the following features:
• The device can operate with an input voltage ranging from 110VAC to 220VAC.
• Ease of access to device pins with test points and sockets pins.
• The setup process for testing is simple
• Designed to detect earth leakage current in AC systems
• Used for testing and evaluation of leakage detection circuits (not for direct protection use)
• Operates directly from AC mains (110V–220V AC)
• Includes internal blocks: regulator, differential amplifier, comparator, and latch circuit
• Works with zero-phase current transformer to sense leakage current
• Trip detection range around ~39–48 mA leakage current
• LED indicator for operation status (fault detection)
• Provides test points and socket pins for easy measurement and debugging
• Screw terminal connections for AC input and wiring
• Intended for lab testing, evaluation, and development of circuit breakers (ELCB/RCD systems)
• High-voltage board — not safe to touch during operation
Layout
Hardware
The GL7101 Module is intended to provide basic functional evaluation for the GL7101 device. The fixture layout is not intended to be a model for the target circuit. GL7101 Module as the board is designed to connect to a high-power AC source. The entire board uses high-voltage, thus the parts of it are not safe to touch when it is connected to a live source. The GL7101 Module is not designed to actually break or interrupt the source voltage in case a fault current is detected.
