An external resistor whose value =(V 2.5 volts) 0.012 IN Amps is a good choice for limiting input current. TYPICAL OVERLOAD TRIP CURRENT VS. TIME 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 speci ed for load supply voltages to 60 Vdc maximum. 7. For through-hole-PCB-solder-attaching ZD20CD series relays, the wave-solder or solder pot operations are limited to +260C maximum for 10 seconds, maximum. 8. For surface-mount-solder-attaching SZD20CD series relays, in IR heating or convection heating systems, the component temperature is limited to +235C maximum for 10 seconds Figure 7 maximum.
