Description
The 186431B-02 cFP-RLY-423 Relay Output Module by National Instruments is designed for AC/DC switching in Compact FieldPoint applications, with four SPDT relay channels and LED status indicators. Ideal for tasks requiring precise control of switching devices, this module provides power to connected devices and includes internal protection MOVs on each channel.
The 186431B-02 cFP-RLY-423 Relay Output Module by National Instruments is designed for AC/DC switching in Compact FieldPoint applications. It features four single-pole double-throw (SPDT) relay channels with LED status indicators, 250 VRMS maximum isolation voltage, and 2,300 VRMS transient overvoltage protection. Hot swappable and intended to be mounted on a cFP-BP-x Compact FieldPoint Backplane, this module provides power to connected devices. Each relay channel has one normally open (NO), one normally closed (NC), and two isolated common (IC) terminals, with break-before-make functionality. Users can control relays individually or simultaneously. Inductive loads connected to the module can generate harmful flyback voltages, but protections like flyback diodes or MOVs can mitigate this issue. The cFP-RLY-423 also includes internal protection MOVs on each channel to prevent high voltage damage. Ultimately, this reliable and versatile module is ideal for tasks requiring precise control of switching devices.
