LED and Built-in Varistor Types RM 23, RM 40, RM 48, RM 60 • Zero switching (RM1A) or instant-on switching (RM1B) AC Solid State Relay • Direct copper bonding (DCB) technology • LED indication • Built-in varistor 230, 400, 480 V • Clip-on IP 20 protection cover • Self-lifting terminals • Housing free of moulding mass • 2 input ranges: 4.5-32 VDC and 24-265 VAC/24-190 VDC • Operational ratings up to 100 AACrms and 600 VAC • Non-repetitive voltage: Up to 1400 Vp • Opto-insulation: > 4000 VACrms Product Description Ordering Key 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 control. The built-in varistor secures transient protection for the heavy industrial applications, and the LED indicates the status of the control input. The clipon cover is securing touch protection to IP 20. Protected output terminals can take cables up to 16 mm2.
