Integrated Thermal Protection
The SSR temperature is constantly monitored. If the maximum temperature limit
(230°F/110°C) is exceeded, 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 which actuates a wired device during an
alarm event, such as a horn or light. This output alarm requires an external 24 VAC/
DC power supply.
Alarm Output Ratings: Imax........................................................................150 mA
Vmax................................................................. 32 VAC/DC
Z close (impedance) ................................................ < 15 Ω
For Models with 24 VDC 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 (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 (Code 1)
• There is no current on the load (Alarm Option Code 2)
• There is no line voltage power supply (Alarm Option Code 2)
Environment Conditions

Pollution Level: ..........................................................................................................2
Storage Temperature:............................................................................ -20˚C to 85˚C
Junction Temperature:....................................................................................... 125˚C
This device conforms to ECC 2004/108/CE and 2006/95/CE and subsequent
modifications including with reference to product standard EN 60947-4-3 (Low-
voltage switchgear and control gear – AC contactors and semiconductor motor
starters). The product is designed for type A environments. Use of the product in
type B environments may cause undesired electromagnetic noise. In this case, the
user should take appropriate steps for improvement.
