Overview
These Units process IO with digital signals.
These Units process inputs with digital signals.
These Units process outputs with digital signals.
These Units process IO with analog signals.
These Units process inputs with analog signals.
These Units process outputs with analog signals.
These Units process inputs from temperature sensors.
Heater Burnout Detection Units have the following functions.
• Monitoring of CT currents to provide alarms for heater
burnouts and SSR failures
• Time-proportional control output processing to operate
heaters with SSRs
System Units are used as required to build an IO Device
Terminal.
This Unit is used when the NX Unit power supply is not suffi-
cient.
This Unit is used when the IO power supply is not sufficient
or to separate the power supply in the IO Device Terminal.
This Unit is used when the IO power supply terminals for
connections to external IO devices are not sufficient.
This Unit is used to ground more than one shield wire from
external IO connections to the same ground.
These Units perform input processing of the output signal
from a load cell to measure the weight or force.
This Unit receives signals from the temperature sensor and
controls the heater temperature to match the set tempera-
ture.
These Units perform IO processing of position data for posi-
tioning.
These Units count pulses from incremental encoders.
These Units process serial signal inputs from absolute
encoders or linear scales that have an SSI interface.
These Units use Radio-Frequency Identification.
