I/O Interface and System Design

The block I/O may be used to drive a variety of output devices. Typical
output devices compatible with the block I/O outputs include:
motor starters
solenoids
indicators
When designing a system, ensure that the block I/O output can supply the
necessary surge and continuous current for proper operation. Take care to
ensure that the surge and continuous current are not exceeded. Damage to
the module could result.
The block I/O outputs are capable of directly driving the block I/O inputs
of the same type.
AC Outputs
The ac output circuits for block I/O are capable of driving ac loads with a
maximum surge current (inrush) of 10A/1200 Watts and a maximum
holding current of 300mA/36 Watts at 60
o C (600mA/72 Watts at 30 o C).
The maximum drive characteristics are shown below.
