DESCRIPTION
SG pin-out is compatible with standard OAC type I/O modules,
and all models are available withrandom turn-on as an alternative
to zero-cross turn-on.The SG SSR range offers a choice of
240VAC, 380VAC, 480VAC versions. Input Voltage specifications
have 3 to 15VDC, 15 to 32VDC and 3 to 32VDC.
PRECAUTIONS
1． Soldering must be completed within 10 seconds at 260 or less or within 5 seconds at 350 or less.
2． The SSR case serves to dissipate heat. Install the relays so that they are adequately ventilated. If poor ventilation is unavoidable, reduce the load current by half.
3． The input circuitry does not incorporate a circuit protecting the SSR from being damaged due to a reversed connection. Make sure that the polarity is correct when connecting the input lines.
4． When using the SG series for an AC load with a peak voltage of more than the rated, connect the load terminals of the relay to an inrush absorber (varistor).
For 220VA the recommended varistor voltage is 470V; For 380VAC, the recommended varistor voltage is 750V.
