Solid State Optronics AC Output Solid State Relays (SSRs) provide an optically isolated means of switching AC loads. Offered with either SCR or TRIAC output structures, and with either ZVC (Zero Volt Cross) or RP (Random Phase) switching, AC Output SSRs tend to be more robust than their MOSFET Output counterparts, typically making them better suited to industrial switching applications wherein a load may connect directly to an AC line.

Advantages

SSO AC Output Solid State Relays come in a variety of packages and output types, ranging from a 6-pin DIP and 16-pin DIP to a 4-pin SuperSIP, with blocking voltages up to 800 V. They offer all the benefits of solid state switching technology including:

  • High blocking voltage, up to 800 V
  • Switching AC loads without the generation of transients (ZVC devices)
  • High input-to-output isolation (5000 Vrms)
  • Long life, bounce-free switching
  • Compact package size
  • High input-to-output noise immunity
  • Random Phase and Zero Volt Cross switching

One product family. Two output switching types.

While all SCR output-based relays naturally turn off at zero current, these two types of device differ in where they turn on within the AC cycle. Zero Volt Cross (ZVC) devices turn on within a small window about zero volts — SSO specifies a ±5 V window — thereby avoiding the creation of transients. Random Phase devices will turn on anywhere within the AC line cycle upon application of an input signal, and are typically used in dimming applications.

Applications

Functionally equivalent to a discrete optically isolated TRIAC (or back-to-back SCR) circuit, SSO's family of AC Output Solid State Relays provides an integrated optically isolated switching solution to applications in:

  • Programmable control
  • Valve control
  • Solenoids and coils
  • Home appliances
  • Metering equipment
  • Heating controls
  • Dimmer controls
  • Process controls
  • Contactors
  • Motor controls
