Description
The FieldPoint module, identified by part numbers 185151C-01 / 777518-420, is designated as model FP-RLY-420. This module is an 8 channel SPST Relay Output Module that is noted for its use in specific applications but is not recommended for new designs. It features 8-Channel, SPST type relays, making it versatile for various applications.
The switching capacity of the module can handle up to 3 amperes, with an operating voltage range up to 35 VDC or 250 VDC. Each channel’s terminal configuration is designed with NO and IC connections, providing flexibility in setup. The module’s Vsup and COM terminals are connected internally, simplifying the wiring process. For protection, a fast-acting, 3 A, 250 V fuse is recommended.
The relay type utilized within this module is the electromechanical (SPST) relays, known for their reliability. Upon power-on, the module’s state is Off, ensuring safety and energy efficiency. The effective resistance between IC and NO terminals is approximately 150 mΩ, indicating minimal internal resistance and efficient operation.
For enhanced durability and device protection, the module includes integrated MOVs. It also boasts an isolation rating of 250 Vrms continuous, providing significant protection against voltage transients. The switching frequency capability of the module reaches a maximum of 20 operations per second, with electrical switching frequency designed for 1 operation per second at maximum load. The module’s operate, release, and bound times are 8 ms, 4 ms, and 4 ms respectively, demonstrating its swift response capabilities.
