The solid-state SIR Series Relays are designed for industrial applications requiring rugged, reliable operation. These relays provide an optically-isolated, high-capacity, solid-state output with power switching capability up to 20 A steady state, 200 A inrush. The SIR2 zero voltage switching is intended for resistive and incandescent loads and can extend the life of an incandescent lamp up to 10 times. The SIR1 random switching is intended for inductive loads. When fully insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections.

Operation The solid-state output is located between terminals 1 and 3 and is normally open or closed without control voltage applied to terminals 4 and 5. When control voltage is applied to terminals 4 and 5, the solid-state output opens or closes, respectively.

Reset Removing control voltage resets the output. The unit can also be reset if the output voltage is removed.

特長:

  • Inductive, resistive, and incandescent loads
  • Industrial systems requiring rugged, reliable operation
