KL2702 | 2-channel solid state load relay up to 230 V AC/DC

The KL2702 output terminal uses an electronic load relay to switch a mains voltage of up to 230 V AC/DC. 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 KL2702 terminal has two independent outputs. Its signal state is indicated by means of light emitting diodes.
