EEnergy
saving
| @ |
Auto-light function |
| @ |
Display brightness is controlled after measurement
from the front light sensor. This saves energy when connecting
multiple units. |
| @ |
@ |
@ |
| @ |
Display-off function |
| @ |
Displays are turned off when operation does not
occur for the time set during Indication time setting. PV, SV
or no indication is selectable during Display selection mode
by keypad. |
| @ |
@ |
@ |
EI/O for each channel is
individually selectable.
| @ |
Input |
| @ |
Individually selectable from thermocouple, RTD,
DC current, DC voltage for each channel. Also infrared thermocouples
(RD-300 series, RD-401) are usable.
(e.g.) CH1 input: Thermocouple
@@@ CH2 input: DC voltage |
| @ |
@ |
@ |
| @ |
Output |
| @ |
Selectable from Relay contact, Non-contact voltage
and DC current output.
(e.g.) CH1 control output: Relay contact output,
@@@ CH2 control output: DC current output |
| @ |
@ |
@ |
EInput
sampling period selectable
| @ |
Select from a choice of: 25ms, 125ms, 250ms
via keypad.
High accuracy control can be performed by selecting optimal
sampling period. |
| @ |
@ |
@ |
EBlock function provided via
console software
| @ |
Block function can be used through console
software.
For each channel, Input block, Control block and
Output block can be freely selected and combined.
Customizable specifications for various usages.

Input 1 block function |
| @ |
PV difference input
[Input 1 block] receives (Input 1 - Input 2) or (Input 2 - Input
1), then outputs to [Control 1 block].
PV addition input
[Input 1 block] receives (Input 1 + Input 2), then outputs to
[Control 1 block].
|
| @ |
Input 2 block function |
| @ |
PV difference input
[Input 2 block] receives (Input 1 - Input 2) or (Input 2 -
Input 1) , then outputs to [Control 2 block].
PV addition input
[Input 2 block] receives (Input 1 + Input 2), then outputs
to [Control 2 block].
@

| @ |
Control 1 block, Control
2 block function |
| @ |
Heating/Cooling control output
Heating/Cooling control computation is carried out in [Control
1 block],
then outputs from [Output 1 block] to [Output 1 (Heating)]
and [Output 2 (Cooling)].
External setting input (Remote)
[Input 2] receives External input. Control computation is
carried out using [Control 1 block] value received from [Input
2 block] output, then outputs from [Output 1 block] to [Output
1].
Cascade control
CH2 is a master (1st-order controller), and CH1 is a
slave (2nd-order controller).
Control computation is carried out at [Control 2 block]
of the master (1st-order controller). Its output will become
the set value of [Control 1 block] of the slave (2nd-order
controller), and control computation is carried out using
this value, then outputs from [Output 1 block] to [Output
1].
@
|
| @ |
Output 1 block function |
| @ |
Output 2 output
[Output 1 block] receives [Control 1 block] output, and
outputs to [Output 2].
1-input, 2-output
[Output 1 block] receives [Control 1 block] output, and outputs
to [Output1] and [Output 2].
|
| @ |
Output 2 block function |
| @ |
Transmission output
Selects the PV, SV or MV via Console software or keypad operation,
and outputs from [Output 2 block] to [Output 2].
|
| @ |
In addition to the above, the following functions
can be used.
EReading and setting of SV, PID and various set values.
EReading of PV and action status
EFunction change |
