Description                             

The SZ1145 is a microprocessor-based monitoring and 
alarm interface designed to monitor up to four 1000 

Ω

 

platinum temperature sensor inputs and up to two 4-20 
mA inputs.  The RTD inputs, scaled 20 to 120°F (-6.7 to 
48.9°C ), are suitable for monitoring temperatures in this 
range.  If any of these inputs exceed their high or low 
limits, the alarm output relay is energized.

Features                                 

• Stand-alone or network operation
• Independently programmable high and low limits for 

each input

• Independently programmable manual or automatic 

alarm reset

• Change of state factor with programmable hysteresis
• 32 character LCD display
• Two Status LEDs 
• Relay output to activate additional auxiliary communi-

cation devices or external alarm circuit

• Direct RTD temperature inputs
• Two 4-20 mA analog inputs suitable for a broad variety 

of transducers

Mounting                                

The SZ1145 is designed for mounting using two #10 
sheet metal screws.
