Delem DA 24E Control Unit

The Delem DA‑24E is a compact membrane keypad controller used on CNC and press‑brake machines for operator input and basic motion control. Common failure modes include loss of power supply (12 V DC), degraded keypad contact wear or shorting, firmware corruption that causes the unit to hang or display error codes, and I/O communication faults with the host PLC. First‑check diagnostics: verify the 12 V DC rail is present and within spec; visually inspect the keypad for cracked or corroded contacts; review any displayed error codes in the panel’s log; and test serial/Modbus links to confirm proper data exchange with the machine controller.[oss-gpt-20b] Post Comment
