Product Description
RoHS CompliantLifecycle Status:Successor:
The Digital Monitoring Relay is an advanced device designed for precise current monitoring. It features a robust design capable of handling currents ranging from 2 to 500 mA in both AC and DC environments. The relay is equipped with overshoot and undershoot capabilities, ensuring accurate readings even under varying voltage conditions (24-240 V AC/DC) at frequencies between 50 to 60 Hz.
The relay incorporates a unique startup delay feature, which can be adjusted from 0.1 to 20 seconds, and an interf. peak delay of up to 20 seconds. It also offers hysteresis control, allowing for adjustments between 0.1 to 250 mA. The relay's changeover contact is spring-loaded, providing reliable performance.
The Digital Monitoring Relay can be configured with or without an error log, enhancing its functionality and versatility. Its robust design and advanced features make it a valuable addition to any automation system.
