Depending on your pulse receiver and cable, an additional external load resistor (at least 10% of rated current) may improve pulse signal quality and noise
immunity.
2
Relay lifetime with a lamp load will be reduced by 75% unless steps are taken to reduce the turn-on surge below the surge current rating of the output.
3
Lamp load wattage rating is for rated voltage. Reduce the wattage rating proportionally for voltage being switched (for example 120 VAC - - 100 W).
Warning
When a mechanical contact turns on output power to the S7-200 CPU, or any digital expansion module, it
sends a "1" signal to the digital outputs for approximately 50 microseconds.
This could cause unexpected machine or process operation which could result in death or serious injury to
personnel, and/or damage to equipment.
You must plan for this, especially if you are using devices which respond to short duration pulses.
