Digital Input and Output Modules
Relay Output Modules
Electrical isolation from the internal and external circuitry is achieved by the coils and the con-
tacts of the output relays.
Modules are available as multiple outputs with isolated grouped commons or as individually
isolated "volt-free" outputs (QY18A).
Similar to the other types of output modules, the operation of the output contact is driven by the
internal CPU program. At the end of the program the PLC will refresh (update) the outputs
from the output latch memory, an LED will light and the output contact will close. The response
for the operation of the relay is approximately 10 ms.
