External dimensions

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

WCL-13A_block_initial

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].

WCL-13A_block_addition_input1
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].

WCL-13A_block_addition_input2

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)].

WCL-13A_block_Heat/Cooll

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].

WCL-13A_block_external_setting

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].

WCL-13A_block_cascade


Output 1 block function
Output 2 output
[Output 1 block] receives [Control 1 block] output, and outputs to [Output 2].

WCL-13A_block_output2

1-input, 2-output
[Output 1 block] receives [Control 1 block] output, and outputs to [Output1] and [Output 2].

WCL-13A_block_2outputs

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].

WCL-13A_block_transmission


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
