Single-phase solid state relays, SO8 series
Synchronous solid state relay suited to most loads.
Voltage protection for input (transil) as well as output (VDR) for high immunity to interference.
Wide control range: 3 → 32 Vdc with regulated control current.
Green LED input display.
Solid state relays must be mounted on a heatsink.
