Ground Fault Detection
Description
16-channel isolated barrier, 24 V DC supply (Power Rail), Analog or digtial field device inputs, Monitors leakage current, Fault relay contact output, LED status indication, Test circuit for validation, Parallel connection for easy integration, Conformal coatingpa. This isolated barrier is used for intrinsic safety applications. The device detects ground faults on field lines. The 16 channels of the device continuously monitor galvanically isolated circuits and warns if their resistance to ground falls below 10 kΩ. During an alarm condition, the appropriate channel LED is illuminated and the change-over contact is initiated (S1 = position I). The function of this relay can be reversed with switch S1 (S1 = position II). A self-test can be activated via the test input of the device. The device reacts by switching the relay. The self-test can be triggered manually by the user or remotely by the control system.
