KL2701 | 1-channel solid state load relay up to 230 V AC/DC, 3 A

The KL2701 output terminal uses an electronic load relay to switch a mains voltage of up to 230 V AC/DC with an output current of 3 A. The switching element is a high-power MOSFET, which is connected to the power contact potential. As a semiconductor switch, it is not subject to wear. The KL2701 terminal has one independent output. Its signal state is indicated by means of a light emitting diode.
