Unlike the Tormach I/O board, this one does not rely on power from the host computer via the USB cable. Instead, our I/O card has a separate connector for 24Vdc. Your Tormach mill already has a 24V supply in its wiring cabinet and this is ideal. The maximum total power draw of the I/O board is 1.5A and there is an onboard, self-resetting fuse to limit it even under fault or short circuit conditions. The 4 outputs are opto-isolated, open collector transistor that act as switches to the 24V ground connection. The output connector has 8 pins, with the 24V supply’s +ve and the 4 outputs alternating. This makes it neat and simple to wire relay coils or pneumatic solenoid valves as the two wires to the coil connect to adjacent terminals on the USB I/O’s output connector. Inputs The inputs are also opto-isolated and these require 2.5mA to activate. One end of the isolator input is connected to the +ve side of the 24V power supply, so to activate the input, you simply short it to ground. The input connector has alternating ground and input pins, so any switch type sensor can simply be connected between adjacent pins on the input connector.

Lot of three Thorlabs CCM1-4ER/M cage cubes with lock rings, plus one CP36 coupler plate. All 3 are populated with BS022 beamsplitter cubes (as etched on the internal prisms); the third cube is present with a plug/cap. All three feature SM1-threaded ports and 30 mm cage compatibility for quick integration into existing ER-rod assemblies.
