• Terminal blocks can be detached and attached. Both screw terminals and
screw-less clamp terminals are available.
• Connect a current transformer (CT) to use the heater burnout and heater
overcurrent alarms (TC2 Units only).
• Up to eight G3ZA Multi-channel Power Controllers can be connected to
one Basic Unit.
• The HFU performs gradient temperature control or 2-PID control (set for
each group).
• Gradient temperature control can be performed for from 2 to 32 channels.
(2-PID control can also be set by group for from 2 to 32 channels.)
• Two-channel gradient temperature control can be performed for up to 16
groups (when TC4 and TC2 Units are used) or 32-channel gradient tem-
perature control can be performed for up to 2 groups (when TC4 Units are
used).
• Up to sixteen Basic Units can be connected to one HFU.
• Data can be exchanged between the EJ1G and PLCs using programless
communications.
• Up to 300 data items can be read from a PLC to the EJ1G and up to 300
data items can be written from the EJ1G to a PLC.
• OMRON CS/CJ-series PLCs and Mitsubishi Q/QnAS-series PLCs can be
connected.
• The End Unit supplies power to connected Basic Units and HFUs.
• An End Unit is always required when using the EJ1G.
• A total of up to 16 HFUs and Basic Units can be connected to one End
Unit.
• Port A is split into both a connector and a terminal block. The connector is
used with the Support Software and the terminal block is used for EJ1G
distributed placement. (Port B is also used for distributed placement.)
• When using port A, be sure to consider the write life of the EEPROM.
