User defined combinations

The following can be selected.

Space saving

• 2ch, but so compact !
• Economizes the control panel.
• 30 x 88 x 110mm (W x H x D, including the socket)

Energy 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.

I/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

Input sampling period selectable

• Select from a choice of: 25ms, 125ms, 250ms via keypad.
• High accuracy control can be performed by selecting optimal sampling period

Block 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.

Initial selection status

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-outputs

• [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.

• Reading and setting of SV, PID and various set values.
• Reading of PV and action status
• Function change
