Description
The 777518-420 FP-RLY-420 Relay Module by National Instruments is designed for applications requiring reliable SPST relay outputs, with eight channels capable of switching up to 3 amperes at either 35 VDC or 250 VDC. This module offers flexibility and ease of installation with integrated protection MOVs to prevent damage from high voltage, making it a trusted choice for many applications despite not being intended for new designs.
The 777518-420 FP-RLY-420 Relay Module for FieldPoint by National Instruments is specifically designed for applications requiring reliable SPST relay outputs. This module features eight channels, each capable of switching up to 3 amperes at either 35 VDC or 250 VDC. With two terminals per relay channel (NO and IC), this module offers flexibility and ease of installation. Additionally, the NI FP-RLY-420 includes integrated protection MOVs to prevent damage from high voltage. The high-quality relays provide a maximum switching frequency of 20 operations per second and a rated operate/release/bind time of 8 ms, 4 ms, and 4 ms respectively. With 250 Vrms continuous isolation and a fast-acting fuse option for added protection, the NI FP-RLY-420 is a reliable and efficient solution for your relay output needs. Note that this module is not intended for new designs, but it remains a trusted choice for many applications.
