National Instruments cFP-RLY-425 Relay Output Module for Compact FieldPoint

The cFP-RLY-425 (Part number: 777318-425) is a Relay Output Module for Compact FieldPoint. This module has been developed by National Instruments. The cFP-RLY-425 is used for switching signals. This module features a HotPnP option, which allows the software to automatically detect and identify the module when connected. The module is used for many switching applications, such as controlling power circuits. The NI cFP-RLY-425 module is also used for switching indication lights and motors. This module does not need any terminal block. A special feature of the cFP-RLY-425 is the provision of double insulation.

The cFP-RLY-425 Relay Output Module incorporates eight non-latching relay channels. The relay type of these channels is SPST and normally open. The module can control both AC and DC signals. The AC input range of the module is 250 V. The corresponding current range is 3-5A. The cFP-RLY-425 also supports up to 125 VDC load. The DC input current range is 0.2-5 A. The module has switching-power up to 750 VA or 90W. The module can perform switching at a maximum frequency of 0.5 Hz. The minimum load of the NI cFP-RLY-425 at 5 VDC is 1 mA. The Relay Output Module’s expected life is 2 x 10⁷ mechanical operations. The material used in the relays’ contacts is a silver alloy that is gold-plated.

The cFP-RLY-425 module is a high power consuming device. Therefore, a limited number of modules can be interfaced with it. The required power is 1.45W. The cFP-RLY-425 is equipped with 2 LEDs that indicate the POWER and READY status.
