Description
The product with the part number 189419E-51L falls under the C Series Digital I/O category. This particular model, the NI-9481, features 4, SPST Relays for efficient signal switching. It is capable of handling a Switching Voltage (DC) of up to 30 VDC (2 A), 60 VDC (1 A), and a Switching Voltage (AC) of up to 250 VAC (2 A), making it versatile for a variety of applications.
Designed to be compatible with NI CompactDAQ or CompactRIO chassis, this module ensures easy integration into existing setups. Each channel is equipped with an LED indicator for quick status checks at a glance. For connection flexibility, it utilizes interchangeable, CHa and CHb terminal types. To ensure a secure connection, 2-wire ferrules are recommended.
To maintain performance in environments subject to vibration, the use of ferrules or the NI-9932 backshell kit is recommended. This ensures that the device remains reliable and durable under various operational conditions.
