Product Details

The Delem 7389-006/-2 is an original OEM I/O circuit board designed for Delem press brake CNC control systems. This press brake I/O circuit board handles digital input and output signal transmission, safety loop detection and actuator triggering for the sheet metal bending machine. As a reliable CNC signal interface board, it connects the Delem main controller with foot pedals, limit switches, safety light curtains, hydraulic valves and relay units, supporting the full set of controlled axes including Y1, Y2, X, R, Z1 and Z2. This Delem replacement board is widely stocked as an original spare part for maintenance and retrofit, restoring normal automatic bending cycles for legacy Delem DA and DM series press brake controllers.

Supported Functions

This press brake I/O circuit board receives discrete feedback signals from limit sensors, foot switches and safety components. The CNC signal interface board outputs switch commands to hydraulic proportional valves, relays and auxiliary machine actuators. It monitors safety chain status and triggers system interlock protection once abnormal signals are captured. This Delem replacement board supports stable long-term signal exchange and allows direct substitution to shorten machine downtime during overhaul.

Core Functions

Opto-isolation circuits separate field power signals from the main control bus to suppress electromagnetic interference inside the workshop. The press brake I/O circuit board transfers safety feedback and motion trigger signals accurately to guarantee safe operation of bending cycles. It cooperates with the main controller to implement axis limit protection, pedal enable and emergency stop logic. Onboard fault detection sends channel error messages to the Delem HMI for fast troubleshooting. Its original pin layout enables plug-and-play replacement without complicated wiring adjustment.
