Beckhoff KL2722 Bus Terminal Bus Terminal
2-channel triac output terminal 12-230V AC, 4-wire system, 1 A with mutually locked outputs
The KL2712 and KL2722 output terminals use a power switch to control mains voltage from 12 V 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 (KL2712) or 1 A (KL2722). The KL2712 terminal has two independent outputs. Its signal state is indicated by means of light emitting diodes. The KL2722 has two mutually locked outputs. 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.
