This is a product that has been developed for our RTR CNC controllers. It’s a device that protects the inputs of the USBCNC CPU (4&5b) and allows sensors of almost any type to be easily connected, using industry standard m12 sensor connectors. When a short circuit is made or if an incorrect voltage is attached, only the optocoupler will be broken...
We use this module in all our RTR controllers. It has two 230V solid state relays. These relays are most often used used to switch a KRESS milling motor(Tool) and a coolant pump(Flood). The module interfaces with USBCNC CPU V4 or V5, via a ribbon cable. On the PCB there are 2 jumpers allowing you to choose which signal from USBCNC controls the relays...
The USBCNC interfaces have ribbon cable connectors. These work very well with all our plug and play devices. But sometimes one of the outputs on the USBCNC board needs to be used multiple times. In that case this signal multiplier is a nice product. It allows one ribbon cable connection to be duplicated 3 times.
This is a handy device we often use for testing equipment. It has several features integrated in one product. We most often use it for easy connection of wiring to ribbon cables(10/20/26 pole). But it also has gender changer for 25 pole SUB-D connectors. It can be combined with USBCNC CPU5A for more easy connection than the normal solder connection.
We use this circuitboard already for several years in our RTR controllers. It is integrated as a standard item in the RTR performance, to activate/deactivate the electormechanical brake often used in the Z axis of CNC routers. But it is also possible via a jumper to select a different channel like Tool or Flood to switch the relay on the board...
USBCNC CPU V3 V4 and V5B use 10 pole ribbon cable (flat cable) to make connections to the stepper drives or servo drives. Since often mistakes were made here in wiring, we developed already a few years ago a small PCB that goes into the stepper drive. Then no wiring is needed anymore. All that is needed is a 10 pole ribbon cable between the USBCNC CPU and the stepperdrives...
