PNP-compatible wiring

The accessory converts the level indicator’s output configuration into a 3-wire PNP (Active High) compatible interface, simplifying direct integration with the digital input modules of industrial PLCs.

Thanks to a factory-installed electrical jumper between the 24V DC power supply line and the common terminal of the SPDT electromechanical contact, the level indicator provides a +24V DC output signal when the detected material level is reached (default NO configuration).

Key advantages:

• PLC Compatibility: native 24V DC output signal (Active High), ideal for standard interfacing with industrial automation systems.

Wiring specifications:

• Required power supply: 24V DC (direct current)
• Output type: 3-wire PNP, Active High (24V DC when the signal is active)
• Default logic: NO (Normally Open) / reversible to NC
• User terminals: +24V DC (power supply), 0V / GND (return), OUT (+24V DC signal to PLC)
