 Data Sheet |
Configure System 
The National Instruments SCXI-1167 is a 64-channel external relay driver, capable of providing up to 50 V or 600 mA of drive capacity (with an external supply). The relay driver is the ideal choice when the current and voltage requirements for relays exceed those found in existing relay modules (or for relays embedded in a test system). The NI SCXI-1167 includes overcurrent, overvoltage, and flyback protection to ensure long-life operation. The SCXI-1167 can also drive small DC motors or other inductive relay coils.
