RAM1A

Solid State Relays Industrial, 1-Phase ZS (IO) w. LED Types RAM1A, RAM1B • Zero switching (RAM1A) or instant-on switching (RAM1B) AC Solid State Relay • Direct copper bonding (DCB) technology • LED indication • Clip-on IP 20 protection cover • Self-lifting terminals • Housing free of moulding mass • 2 input ranges: 3-32 * and 20-280 VAC/22-48VDC • Operational ratings: Up to 125AACrms and 600VACrms • Blocking voltage: Up to 1600Vp • Opto-isolation: > 4000VACrms • Integrated overvoltage protection by self switching (suffix “Z” option) Product Description The industrial, 1-phase relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero. The instant-on relay with DC control input can be used for phase angle control. The built-in snubber secures transient protection. The LED indicates the status of the control input. The clip-on cover secures touch protection (IP 20). Protected output terminals can handle cables up to 16 mm2.
