64-Channel Relay Switch Module for SCXI—The SCXI‑1167 is an external relay driver. The SCXI‑1167 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 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.
