Loads may be connected to either the positive or negative output terminals. ZD24CC Relays act as electronic circuit breakers that sense shorted loads or other overload no current flows through the relay and associated loads. These relays prevent overcurrent damage to the system. ZD24CC Series Relays have Trip Status to indicate a latched-off relay condition. Cycling the relay on-off removes the tripped or latched-off condition and returns the relay to the normal operating state.

The ZD24CC relay’s input current should be limited to between 8 and 20mA. An external resistor whose value =(VIN – 2.5 volts) ÷ 0.012 Amps is a good choice for limiting input current. 2. Relay input transitions should be less than 1.0 millisecond. 3. Loads may be attached to either the positive or negative output terminal. 4. Maximum load current ratings are with the relay in free air and soldered to a printed circuit board. 5. Timing is measured from the input current transition to the 10% or 90% points on the output voltage transition. 6. Overload conditions (including shorted loads) are specified for load supply voltages to 60 Vdc maximum. 7. For through-hole-PCB-solder-attaching ZD24CC Series Relays, the wave-solder or solder pot operations are limited to +260°C maximum for 10 seconds, maximum. 8. For surface-mount-solder-attaching SZD24CC Series Relays, in IR heating or convection heating systems, the component temperature is limited to +235°C maximum for 10 seconds maximum. © 2006 TELEDYNE RELAYS (800) 284-7007 • www.teledynerelays.com ZD24 Page 2DSZD24CC Rev B
