ATTENTION

A transient pulse occurs in transistor output when

the external dc supply voltage is applied to the

output common terminals (for example, via the

master control relay). This can occur regardless of

the processor having power or not. For most

applications, the energy of this pulse is not sufficient

to energize the load. Refer to SLC 500 Modular

Hardware Style User Manual, publication

1747-UM011, for more information on transient

pulses and guidelines to reduce inadvertent

processor operation.
