Product Description:
The PC-1651-A is a precision-engineered CNC control module designed by Okuma for signal coordination and interface tasks. The module is constructed with reliable 74-series logic ICs and robust passive components, it ensures accurate timing, smooth signal processing and seamless integration within OKUMA OSP systems.
The PC-1651-A CNC Board has a secondary connector shaped like a pin header which allows it to interact with other circuit elements or subsystems that aren’t accessed through the primary edge connection. The module includes fixed-value resistive components that play a key role in controlling the flow of electrical charge, either to limit how much current moves through a circuit or to ensure certain voltages are maintained where needed. It is not a standalone piece and it is meant to operate alongside several other specialized boards in a CNC chassis and it shares data and commands with them. It is featured with electrostatic energy storage devices with values such as 0.2 microfarads and 100 picofarads that temporarily store electric charge and help smooth out electrical noise and also shape the timing of digital pulses. It is also featured with a standard digital logic chip from the 74-series family that are time tested and dependable semiconductors that carry out basic logical operations like switching, comparison and memory latching.
The E4809 series CNC board serves as an intermediary between the main CNC processor and mechanical actuators like punching units and it adapts input/output voltages and shapes signal pulses to meet the demands of physical devices. It comes with a gold finished card edge connector which enables it to plug into a larger control rack or motherboard where it receives power and communicates with the central processing system.
