Connection
KL2512 | 2-channel pulse width output terminal, 24 V DC, switching to negative potential
The KL2512 Bus Terminal enables direct connection of different ohmic loads. The output signal is a pulse-width modulated voltage. The typical load of an LED group or an incandescent lamp is connected between the positive side of the supply voltage and the output of the KL2512. Via the fieldbus the output can be set independently for two channels with a resolution of more than 30,000 steps. The PWM frequency can be changed. The power transistors switch the ground connection and are galvanically isolated from the internal K-bus.
