NI 9485 relay output module

The NI 9485 is an 8-channel relay output module belonging to the C series module. Each channel provides access to solid-state relays (SSRS) with switching voltages up to 60VDC or 30Vrms and switching currents up to 750mA. This means that it can be directly connected to a wide range of industrial equipment, such as motors, actuators and DC devices. In addition, each channel has channel-to-channel isolation, which enhances its reliability and security in complex industrial environments.

The module is widely used in the field of power distribution. It can provide primary protection for overhead lines, cable feeders and bus systems in distribution substations, and is suitable for the protection and control of grounded and ungrounded distribution systems. Its flexible configuration allows users to choose current-only or current-and-voltage configurations to suit different distribution feeder application needs.

In addition, the NI 9485 is the most powerful, advanced and simple feeder protection relay in its class. It is perfectly capable of providing time and instantaneous overcurrent, negative sequence overcurrent, phase discontinuity, circuit breaker failure, thermal overload, voltage metering and protection. The relay also provides optional high impedance fault (HIZ) and sensitive ground fault (SEF) protection for both grounded and ungrounded distribution systems.

In terms of automatic reclosing, the NI 9485 uses a flexible three-phase multi-lens automatic reclosing function. This function can automatically restore the feeder when there is a temporary fault on the overhead line, which improves the stability and reliability of the power system.

Please note that although NI 9485 has the above powerful functions and a wide range of applications, in actual use, it is also necessary to perform reasonable configuration and installation according to specific application scenarios and needs to ensure its normal operation and long-term stability.
