Description
The National Instruments 186431B-01 FP-RLY-422 is a 4-channel Relay Module with integrated module-to-module isolation for safety in controlling low voltage signals up to 125 VDC and 250 VAC. With four independent Form C relays and a compact design, this module provides flexible and efficient control over multiple circuits, making it a reliable option for various applications.
The National Instruments 186431B-01 FP-RLY-422 is a 4-channel Relay Module designed for FieldPoint applications. This versatile module is capable of controlling low voltage signals up to 125 VDC and 250 VAC. It features integrated module-to-module isolation to ensure safety and prevent high voltage levels from reaching the communication interface, FieldPoint system, and controller. The module has a maximum switching capacity of 3 A at 250 VAC or 35 VDC and draws 1.5 W of power in typical conditions. With four independent electromechanical Form C relays, each channel can operate with a different voltage potential due to electrically isolated output relays. This allows for flexible and efficient control over multiple circuits. The relay output circuit has an expected mechanical life of 1 x 107 operations and electrical life of 300,000 operations at 35 VDC, 3 A. The module's compact dimensions of 10.7 x 10.9 x 9.1 cm and weight of 180 g make it a convenient and reliable option for various applications.
