Description
The product encompasses two part numbers, 781421-10 and 781420-10, designed as a Matrix Module for NI SwitchBlock. This module stands out for its ability to configure into a 4 x 43 Matrix, which can be expanded impressively up to a 4 x 1032 matrix. It’s engineered to handle a maximum voltage and current of 150 V / 1 A, along with a peak power capacity of 20 watts.
Efficiency is key with its relay operation time being less than 1 ms for up to 8 relays and less than 2 ms for up to 50 relays, ensuring swift performance. The module’s power requirements for the carrier are specified at 20 watts at 5 V, and 5 watts at 3.3 V, indicating its energy efficiency. Connectivity is facilitated through a 96-position SCSI I/O connector, providing robust and reliable connections.
When it comes to handling multiple operations, this module can manage up to 176 simultaneous relays. Despite this capability, the relay power consumption remains low, with up to 50 mW per relay, culminating in a maximum of 8.8 watts total power consumption. Safety isn’t overlooked, as evidenced by its CAT I device category rating. Furthermore, the system’s voltage limit is safeguarded to be less than 150 V, ensuring a secure operational environment.
