zPainting and coating Plants
zSemiconductor packaging / Testing
zIndustrial Dryers
Features
zEasy to Operate
Different configuration levels provide easy
access to parameters.
zVarious Control Programming
Several different algorithms are available
as follows:
- PID or ON/OFF Control
- Heat/Cool Control with 2 PID sets
- Motor Position Control
(without slidewire feedback)
zAuto-Tuning Capability
Advanced auto-tuning function calculates
the optimized PID values for your specific
control system.
zDual Display and Bar graph
Two large 4 digits display PV, SP and
configuration parameters. One 10 LED
bar-graph displays the control output
(MV), and up to 8 LEDs display the status
of the different outputs (Control, Alarm,
…) and also provide indication of the
Auto/Manual and programmer states.
zSetpoint Programming
Two programs are available with a
maximum of 8 segments. The 2 programs
can be linked together and perform as a
single 16 segment program.
zExtended Alarm Capability
Up to three different alarm outputs are
available per instrument and 17 kinds of
event modes can be assigned to each of
alarm output.
zCommunications
RS232 or RS485 (with ASC II & Modbus
RTU Protocol) is optionally available with
a maximum communication speed of
38400 bps.
zIP65 Front Face Protection
IP65 rated front face permits use in
applications where it may be subjected to
moisture, dust conditions.
zRemote Setpoint Capability
The setpoint can be defined from a
remote PLC or other controller.
zParameter Lock
A 4-digit security code prevents any
unauthorized changes of parameters or
configurations. Parameters can be hidden
to user to prevent any mis-configuration
of the unit.

(1) All the under hookups are only for reference.
(2) For wiring, please according to the hookup label which was glued
on the plastic case of controller.
(1) For thermocouple input, use the specified compensation wire.
(2) For RTD input, use leads with low resistance and having no resistance differences among the 3 leads.
(3) Conduct input signal wiring away from instrument power, electric equipment power and load lines to avoid noise
induction.
(4) Conduct instrument power wiring so as not to be influenced by noise from the electric equipment power. If the
instrument may be affected by external noise, a noise filter should be used.
* shorten the distance between twisted power supply wire pitches. The shorter the distance between the pitches,
the more effective for noise reduction.
* Install the noise filter on the panel which is always grounded and minimize the wiring distance between the noise
filter output side and the instrument power terminals.
* Do not install fuses and/or switches on the filter output signal since this may lessen filter effect.
(5) For wiring, use wires conforming to the domestic standard of each country.
(6) About 4 to 5 seconds is required as the preparation time for contact output after power on. Use the delay relay
when the output line is used for an external interlock circuit.
(7) This instrument has no power supply switch nor fuses. Therefore, install the fuse close to the instrument and the switch,
if required.
* Recommended fuse rating: Rated voltage; 250 V Rated current; 1A * Fuse type; Time-lag fuse
(8) Do not excessively tighten the terminal screws. In addition, use the solder less terminal appropriate to the screw size.
(9) To the instrument with power supply of 24V, please be sure to supply the power from SELV circuit
