KL2702 | Bus Terminal, 2-channel solid-state relay output, 0…230 V AC/DC, 0.3 A

Name: Bus Terminal, 2-channel solid-state relay output, 0…230 V AC/DC, 0.3 A
Brand: Beckhoff
SKU: KL2702

KL2702 | Bus Terminal, 2-channel solid-state relay output, 0…230 V AC/DC, 0.3 A

The KL2702-xxxx 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 terminal has two outputs that indicate their signal state via LEDs.

Special features:

2 x make contact
max. output current
- 0.3 A (KL2702)
- 2 A (KL2702-0002)
- 1.5 A (KL2702-0020)
mutually locked outputs (KL2702-0002)

Product status:

regular delivery
