1 Load current must be full wave AC and must not be half-wave because of the zero-cross circuitry. Minimum l oad current is 0.05 A AC. With a load current
between 5 mA and 50 mA AC, the current can be controlled, but there is an additional voltage drop due to series resistance of 410 Ohms.
2 If the output overheats due to ex cessive inductive switching or abnormal condi tions, the output point may turn off or be damaged. The output could overheat
or be damaged if the output i s s ubjected to more than 0.7 J of energy switching an inducti ve load off. To eliminate the need for this limitation, a suppression
circui t as described in Chapter 3 can be added in parallel wi th the l oad. These components need to be sized properly for the gi ven application.
3 The EM 222 DO 4 x Relay has a different FM rating than the rest of the S7-200. This module has a T4 rating, instead of T4A for FM Class I, Division Groups
A, B, C, and D Hazardous Locations.
4 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.
5 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.
