ABB 1MYN569697-G Trip Circuit Supervision Relay

ABB 1MYN569697 - G is a trip circuit monitoring relay, which belongs to the TCS type monitoring relay. Its relevant information is as follows:

Functional features

Continuous monitoring: It can continuously monitor the circuit breaker trip circuit, which is not affected by the circuit breaker position. It can promptly detect problems such as loss of auxiliary power supply, fault of trip coil or its wire, fault of circuit breaker auxiliary contact and fault of monitoring relay itself, and issue an alarm.

Fault indication: Under normal circumstances, the indicator LED is green and the output relay is in the pickup state. If a fault occurs, the monitoring relay will operate (fall) after a delay of 0.6 seconds, and the LED indicator will turn red, clearly indicating the fault state.

Electrical isolation: There is electrical isolation between the auxiliary power supply and the monitoring circuit, which can enhance the safety and stability of the system and avoid mutual interference.

Adapt to a variety of circuits: Based on the principle of low-level (about 3mA) current injection, it can be used for sensitive or high-resistance circuits, and the burden on the auxiliary source is extremely low. It can work stably in circuits with a variety of different characteristics. At the same time, it has a complete rated AC/DC voltage range, including 24V DC, 30V DC, 48V DC, 100-125V AC/DC, 220-250V AC/DC, etc., which can be adapted to different power systems.

Delayed operation: With delayed operation function, it can avoid false operation caused by stray signals during the operation of the circuit breaker, and improve the accuracy and reliability of monitoring.

Contact configuration: 1NO (normally open) + 1NC (normally closed) + 2C/O (conversion contact), this configuration can meet the connection requirements of various control circuits, and can flexibly realize connection with different devices or circuits to complete various control and signal transmission tasks.
