2-2-2 Types of NX Units
Unit type Overview
Digital IO Units These Units process IO with digital signals.
Digital Input Units These Units process inputs with digital signals.
Digital Output Units These Units process outputs with digital signals.
Analog IO Units These Units process IO with analog signals.
Analog Input Units These Units process inputs with analog signals.
Analog Output Units These Units process outputs with analog signals.
Temperature Input Units These Units process inputs from temperature sensors.
Heater Burnout Detection
Units
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 System Units are used as required to build an IO Device
Terminal.
Additional NX Unit Power
Supply Unit
This Unit is used when the NX Unit power supply is not suffi-
cient.
Additional IO Power Supply
Unit
This Unit is used when the IO power supply is not sufficient
or to separate the power supply in the IO Device Terminal.
IO Power Supply Connec-
tion Unit
This Unit is used when the IO power supply terminals for
connections to external IO devices are not sufficient.
Shield Connection Unit This Unit is used to ground more than one shield wire from
external IO connections to the same ground.
Load Cell Input Units These Units perform input processing of the output signal
from a load cell to measure the weight or force.
Temperature Control Unit This Unit receives signals from the temperature sensor and
controls the heater temperature to match the set tempera-
ture.
Position Interface Units These Units perform IO processing of position data for posi-
tioning.
Incremental Encoder Input
Units
These Units count pulses from incremental encoders.
SSI Input Units These Units process serial signal inputs from absolute
encoders or linear scales that have an SSI interface.
RFID Units These Units use Radio-Frequency Identification.
