Description
The part number for the product is 185151D-01, which has been corrected from its previous designation of 777518-420. This product falls under the category of FieldPoint and carries the model designation of FP-RLY-420. It is described as an 8 ch SPST Relay Output Module, which is not recommended for new designs.
This module features 8-Channel, SPST Relay functionality, with a switching capacity that can handle up to 3 amperes. It is designed to operate with voltages of 35 VDC or 250 VDC. An important aspect of its design is that it does not impact the bank’s operation when installed onto a live terminal base, ensuring ease of integration into existing systems without downtime.
Each relay channel on this module provides NO and IC terminals for connectivity. Internally, the Vsup and COM terminals are connected, simplifying the wiring process for users. A fast-acting, 3 A, 250 V fuse can be installed at the IC terminal to protect against overcurrent conditions.
The relay type utilized in this module is Electromechanical (SPST) Relays, and its power-on state is configured to be Off. The effective resistance between IC and NO terminals is approximately 150 mΩ. For added safety, integrated MOVs provide high voltage protection, ensuring the longevity and reliability of the module.
This module also features 250 Vrms continuous isolation between the communication bus and backplane, enhancing its operational safety. The maximum switching frequency is 20 operations per second, with the electrical switching frequency capped at 1 operation per second at maximum load to prevent overheating and ensure stable operation. Lastly, the operate, release, and bound time are 8 ms, 4 ms, and 4 ms respectively, highlighting the module’s responsiveness and reliability in various applications.
