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 1600V

p

• Opto-isolation: > 4000VACrms

• Integrated overvoltage protection by self

switching (suffix “Z” option)

Product Description

The industrial, 1-phase relay

with antiparallel thyristor out-

put is the most widely used

industrial SSR due to its mul-

tiple 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 cross-

es 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 cov-

er secures touch protection

(IP 20). Protected output ter-

minals can handle cables up

to 16 mm
