DESCRIPTION
PS7122A-1B, -2B and PS7122AL-1B, -2B are solid state
relays containing a GaAs LED on the light emitting side (input
side) and normally close (N.C.) contact MOSFETs on the
output side.
They are suitable for analog signal control because of their low
offset and high linearity.
APPLICATIONS
• EXCHANGE EQUIPMENT
• MEASUREMENT EQUIPMENT
• FA/OA EQUIPMENT
