Product Description:
The E4809-770-164-A is a printed-circuit assembly produced by Okuma for CNC control applications. Classified as an SSU-RD2 divide card, the board plugs into the OSP-P200 numerical control rack and conditions low-level signals used by axis drives and peripheral interfaces. Within an automation cell, the card subdivides reference pulses, routes DeviceNet fieldbus traffic, and delivers auxiliary DC supply rails. These functions allow the control platform to synchronize servo positioning, I/O modules, and safety interlocks without external signal-splitting hardware.
The SSU-RD2 Divide Card (-A) uses onboard logic to perform pulse division for encoder feedback streams. This function supports the OSP-P200 control platform when it requires lower pulse count rates than the motor encoders supply. Incoming auxiliary power is accepted through a D-3100S, 3-pin DC input connector, while regulated outputs leave through a separate D-3100S, 5-pole header. Using distinct plugs helps prevent accidental cross-connection during service. Printed traces terminate on a 0.1-inch grid, and the resulting 5.08 mm terminal pitch keeps solder joints within standard through-hole tolerances for automated insertion lines.
Fieldbus wiring is handled directly on the board rather than through an external coupler. Three DeviceNet sockets are installed so trunk and drop cables can be daisy-chained without additional T-connectors. Each receptacle uses the Hirose model XS2C-D5S7, which aligns its pin assignments with the OSP-P200 master scanner. The connectors are concentrated along one edge to simplify enclosure routing and provide direct access during card removal. The board belongs to the E4809 CNC Boards series and uses a consistent arrangement for its mounting rails, retention clips, and address switches. This fixed arrangement allows the card to fit the designated control rack without changes to panel openings or wiring harness lengths.
