Integrated Thermal Protection
The SSR temperature is constantly monitored. If the
maximum temperature limit (230°F/110°C) is exceed-
ed, current to the load is interrupted and the YELLOW
over-temperature condition LED illuminates.
Alarm Output Option
The Alarm Output is a Solid State Switch (isolated
contact) which controls a connected device during an
alarm event, such as a horn or light.
• Requires external 24 VAC/DC power supply
• Ratings: Imax = 150 mA
Vmax = 32 VAC/DC
Z close < 15 ȍ(impedance)
For Models with 24 VDV Input Control Signal
The alarm output function closes the isolated solid
state output switch when it detects the following fault
condition:
The control signal is active, but:
• The internal temperature limit of the SSR has been
exceeded (Alarm Option Code 1)
For Models with 20 - 260 VAC/DC Input Control Signal
The alarm output function closes the isolated solid
state output switch when it detects any of the following
fault conditions:
The control signal is active, but:
• The internal temperature limit of the SSR has been
exceeded (Alarm Option Code 1)
• There is no current on the load (zero current or inter-
rupted load) (Alarm Option Code 2)
• There is no line voltage power supply (Alarm Option
Code 2)

This device conforms to ECC 2004/108/CE and
2006/95/CE and subsequent modifications includ-
ing with reference to product standard EN 60947-4-3
(Low-voltage switchgear and control gear – AC contac-
tors and semiconductor motor starters).
The product is designed for type A environments. Use
of the product in type B environments may cause un-
desired electromagnetic noise. In this case, the user
should take appropriate steps for improvement.
