Configuration and Limit for Pulse I/O Unit
Configuration Limit with Current Consumption
Internal current consumption for Pulse I/O unit is shown below (at 5V).
Be careful when configuring system, not to exceed the total capacity
limit, considering the consumption of other units.
Mounting of Pulse I/O Unit
●
For NX70 PLC
Pulse I/O unit can be mounted at any location on the basic
backplane.
But it cannot be mounted on power supply unit or CPU unit slots.
There is no limit to the number of Pulse I/O mounting for NX70 PLC.
Restrictions Due to Combination of Pulse
Output Function
Pulse I/O unit sends out pulse and PWM outputs from the same CH.
Up to 4CH are available.
When using combination of pulse and PWM outputs, allocate pulse
ahead of PWM as shown in the following table.
