NI CFP-RLY-423

NI titles the product documentation as the cFP-RLY-423 Four-Channel SPDT Relay Module and explicitly states that the cFP-RLY-423 is a Compact FieldPoint relay output module. NI also states that it mounts on a Compact FieldPoint backplane (cFP-BP-x), which provides operating power to the module. https://docs-be.ni.com/bundle/323605b/raw/resource/enus/323605b.pdf

According to NI, the module provides four single-pole double-throw relay channels, includes LED relay status indicators, and is hot swappable. NI rates the module for switching up to 1.5 A at 35 VDC or 250 VAC. https://docs-be.ni.com/bundle/323605b/raw/resource/enus/323605b.pdf

NI specifies an operating temperature range of -40 to 60 °C for the cFP-RLY-423, along with 250 Vrms maximum isolation voltage and 2,300 Vrms transient overvoltage protection. In NI's Compact FieldPoint migration reference, the cFP-RLY-423 is also listed as a 4 Ch, 0-250 V SPDT 10 Hz Relay module. https://docs-be.ni.com/bundle/323605b/raw/resource/enus/323605b.pdf https://www.ni.com/en/support/documentation/supplemental/14/transitioning-from-compact-fieldpoint-to-compactrio.html
