Solid State Relays Low Voltage AC/DC Control: 5 to 24 V Types RM 23M, RM 40M, RM 48M, RM 60M * Zero switching AC Solid State Relay * Low voltage AC/DC control: 5 to 24 V * Direct copper bonding (DCB) technology * LED indication * Built-in varistor * Clip-on IP 20 protection cover * Self-lifting terminals * Housing free of moulding mass * Operational ratings up to 100 AACrms and 600 VAC * Opto-insulation: > 4000 VACrms Product Description Ordering Key The industrial, 1-phase relay with antiparallel thyristor output is the most widely used SSR due to its multiple application possibilities. This relay has been designed to interface low voltage AC or DC control systems with high voltage 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 builtin 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 safety to IP 20. Protected output terminals can take cables up to 16 mm2.
