Contact board - Import export

The dry contact board (relay card) is used to provide the UPS peripheral monitoring interface. Contact signals can indicate the current status of the UPS. The appearance and pin numbering of the dry contact relay board may differ depending on the UPS model

The RC74201 dry contact card (art. CNRL004) is designed to monitor and control the UPS using potentialfree relay contacts. Monitoring is carried out through the relay contacts built into the card, which switch when the corresponding events occur in the UPS. The dry contact card allows you to remotely monitor the status of the UPS by receiving discrete signals when the relay is activated. The relay contacts are not galvanically connected to the electrical circuits of the UPS. An external power supply must be used to obtain the required signals. It also provides the ability to remotely shutdown the UPS by sending a signal to the corresponding port. The use of relay contacts allows the UPS to be integrated into local dispatch systems at customer sites.
