KL2712 | Bus Terminal, 2-channel triac output, 12...230 V AC, 0.5 A

The KL2712 output terminal uses a power switch to control mains voltage from 12 to 230 V AC. The switching element is a triac, which is connected to the power contact potential. As a semiconductor switch, it is not subject to wear. The steady load capacity of a digital output is 0.5 A. The KL2712 has two independent outputs. Its signal state is indicated by means of light emitting diodes.

The terminals are most suitable for mechanical reverse motors. They are, however, not recommended to be used for controlling LEDs. In this case, proper functioning of these terminals cannot be guaranteed by the manufacturer.
