Single-phase solid state relays, SO9 series
Synchronous solid state relay suited to most loads.
TMS
2
technology thyristor output ensures longevity.
Voltage protection for input as well as output (VDR) for very high immunity to interference.
Wide control range: 20 → 265 Vac / dc with regulated control current.
Green LED input display.
Solid state relays must be mounted on a heatsink.
