Main Unit Functions
Basic Units (TC4 and
TC2)
• The Basic Units are modular temperature controllers with I/O.
• There are two models of Basic Unit: The TC4 with four I/O channels and
the TC2 with two I/O channels.
• Up to eight G3ZA Multi-channel Power Controllers, or V1.1 G3PW Power
Controllers
, can be connected to each Basic Unit.
TC4
• One TC4 Unit controls temperature on 4 channels.
• Multi-input is supported for thermocouple, platinum resistance thermome-
ter, or analog input.
• The type of input can be set separately for each channel.
• Control outputs are pulse voltage outputs.
• Both screw terminals and screw-less clamp terminals are available.
• Terminal blocks can be detached and attached.
TC2
• One TC2 Unit controls temperature on 2 channels.
• Multi-input is supported for thermocouple, platinum resistance thermome-
ter, or analog input.
• The type of input can be set separately for each channel.
• Control outputs are pulse voltage outputs or current outputs
• Connect a current transformer (CT) to use the heater burnout and heater
overcurrent alarms.
• There are two event inputs. Any of the following can be used by setting
event input assignments: Run/stop, auto/manual, remote SP/local SP, and
bank switching.
• Both screw terminals and screw-less clamp terminals are available.
• Terminal blocks can be detached and attached.
Advanced Unit (HFU)
• An HFU monitors the Basic Units and collects data.
• Up to sixteen Basic Units, or 32 version
Units, can be connected to
one HFU.
• Data can be exchanged between the EJ1 and PLCs using programless
communications.
• With version V1.0, up to 300 data items can be read from a PLC to the
EJ1 and up to 300 data items can be written from the EJ1 to a PLC. With
version
, up to 600 data items can be read from a PLC to the EJ1
and up to 600 data items can be written from the EJ1 to a PLC. With ver-
sion
, up to 1,200 data items can be read from a PLC to the EJ1 and
up to 1,200 data items can be written from the EJ1 to a PLC.
