Parallel Port Interface card with Relays Outputs and Safety Charge Pump Option
Parallel Port Interface card with Relays and Safety Charge Pump Option. 12 to 24VDC power
The Ocean Controls Parallel Port Breakout Board for CNC is a parallel (printer) port hardware interface designed for providing Stepper Motor control signals, and incorporates 2 relays for switching devices on and off.
The main circuitry consists of two buffer IC's which boost the weak parallel port signals to a level high enough to drive Stepper Motor Driver Circuits which use Opto-Couplers.
With the safety charge pump option, the board also includes a microcontroller which monitors the CNC software and turns off the relays and output signals when the charge pump signal from the CNC software is lost.
The Breakout Board provides 9 buffered output signals to control up to 4 Stepper Motor Drivers, 5 digital inputs designed for use as limit switch or e-stop inputs, 2 Relay Outputs to control spindles, coolant or vacuums, and a spare output connected directly to the port (available only when the charge pump option is disable).
PLEASE NOTE: When the charge pump option is enable, the board will not do anything unless the charge pump signal (3kHz - 14.5kHz) is present.
