DC solid state relay SMB

AC24VACthree-phase

Overview
The SMB models are two-leg three-phase solid-state relays (SSR). Some second-generation SMB models include a diagnostic function.

sightpac® series
The sightpac® series is a compact 45 mm format with three solid-state outputs controlled by a single input. It operates like a standard solid-state relay: when the input signal is applied, each output conducts load current for its respective phase.
