Description
The 185151D-02L cFP-RLY-421 from National Instruments is a Relay Output Module designed for use with Compact FieldPoint systems, featuring eight SPST electromechanical relays with Part Number 777318-421. This module, meant to be mounted on a cFP-BP-x backplane, has a relay operate time of 8 ms and a recommended operating temperature range of -40 to 55 degrees Celsius, and should be used with a NEMA, IP, or UL listed enclosure for safety.
The 185151D-02L cFP-RLY-421 from National Instruments is a Relay Output Module designed for use with Compact FieldPoint systems. This module, with Part Number 777318-421, features eight SPST electromechanical relays and is meant to be mounted on a cFP-BP-x backplane. It is important to note that if this module is being used for hazardous voltage applications, the cFP-CB-1 Connector Block or an appropriate hazardous voltage cable must be utilized. Each relay channel on the cFP-RLY-421 has two terminals, one NO and one IC. The module has a relay operate time of 8 ms and a relay release and release bounce time of 4 ms. It has a recommended operating temperature range of -40 to 55 degrees Celsius and maximum AC switching power of 375 VA, as well as a maximum DC switching power of 60 W. For linking loads, the user must wire an external power supply to the load and the IC terminal of the channel. Additionally, a quick-acting fuse can be installed at the IC terminal to protect both the module and the load. The module is UL recognized and should be installed in a NEMA, IP, or UL listed enclosure for safe use. With a weight of 4.8 oz. and dimensions of 4.3 x 4.3 x 3.6 inches, this relay output module has an expected mechanical life of at least 2 x 10^7 operations and an expected electrical life of 100,000 operations.
