| Max. 1024-point measurement and control |
Each control module offers controller functionality for up to four units and can be used individually or combined.
When used with a host, the modules offer flexibility in constructing both large-scale and small-scale systems.
Connected
Connecting the modules enables measurement and control of up to 1024 points.
Stand-alone
When used independently, the modules can be used for control or communication with a host.
This make it easy to add monitoring targets.

Program-less connections to PLCs for reduced work
(SIF function) |
The Smart InterFace (SIF) function (program-less PLC communication function) enables direct connectivity to
PLCs from various manufacturers.

Usable as an analog module for reducing initial costs and wiring |
The QX1 series can be used as an analog module, helping to reduce initial costs and required wiring work.

Failure prediction maintenance |
Failure prediction maintenance
Check usage statuses using the following measurement functions.
1. Cumulative heater energization time (QTC1)
2. Cumulative module energization time (QMC1, QTC1)
3. Cumulative relay contact open/close count (QTC1)
In the event of an error, the error number and energization time are saved.
The 10 most recent errors are saved. (Error history: Can be checked with console software) (QTC1)
The input difference detection function makes it possible to monitor for input differences between channels. (QTC1)
Risk avoidance in case of emergency
The output selection function can be used to switch between outputs. (QTC1)
For example, in the event of a CH1 output failure, CH2 output is enabled.
A signal can be output if heater burnout is detected. (QTC1)
[Heater burnout alarm options: Single-phase, 3-phase (3- phase: QTC1-2 only)]
Alarm output signals can be used to start or stop control. (QMC1-C□, QTC1)
[Event input/output (optional)]

Peak power suppression function for lower power equipment costs |
Peak power suppression function
The total current can be set for the module, and power suppression control can be performed when the sum
of the current values set for each channel is less than or equal to the total current.
This can help minimize investments in power equipment.
Example of peak power suppression function output timing
|
Multi-zone connection (Auto-balance control)
Take advantage of uniform control locations (zones) of a control target (group) through linking.
This helps prevent partial burning and mechanical distortion while also reducing adverse effects on product quality.
 
|
Individual output amount settings (output gain, bias control)
If required output amounts are known in advance, such as when controlling heaters in multiplelocations (zones) for
a single input point, uniform control of multiple zones is possible.
Combining output selection functions reduces the number of input terminals needed, initial costs can also be reduced.
 |
Five included control methods for reduced manual labor |
Control characteristics vary depending on the control target.
The QX1 series includes five control methods to meet a variety of control characteristics. |
2DOF PID control
In addition to target value tracking and disturbance responsiveness, this well-balanced system reduces overshooting.
(When using default control action.)
Fast-PID control
This control method emphasizes target value tracking.
This control method works best when replacing the controller with a Shinko product.
(Doing so provides better performance.)
Slow-PID control
This control method prioritizes preventing overshooting rather than attaining a target value.
Gap-PID control
This control method is effective with fast responses such as for flow rates and valves.
(Deviation characteristics are provided within the gap.)
ON-OFF control
This control method is selected for operating devices that turn heaters and other equipment on or off.

|
The numerous LEDs allow users to visually
check statuses and errors on-site. |
 |
Setting can be easily changed using the
console software, making it possible to
manage multiple modules at once.
OS: Windows 10, Windows 11
(Japanese/English)
The plug-in construction of the modules
make replacement incredibly simple.
|
Commercially available cables (Micr USB Type-B) can be
used as connecting cables. |
|
|
|
| Heating/cooling control |
Heating and cooling are controlled with CH1 used as the
heating-side input and CH2 as the cooling-side input. (Up to
2 loops are possible with the QTC1-4.) |
| Cascade control |
The adjusted CH1 variable, obtained from the SV and PV of CH1, is substituted for the SV of CH2, enabling CH2 control calculation and outputting.
(Up to 2 loops are possible with the QTC1-4.)
|
| Heater burnout alarm (optional) |
Detects and outputs heater burnout.
The CT and the connector harness WQ for heater burnout alarm
are sold separately. |
| Event input/output (optional) |
Event input (4 points) or event output (4 points) can be
added.
Connector harness EVQ for event input/output is sold separately. |
| Input difference detection |
Detects the input difference between two channels, and sets
a flag when the difference exceeds the set value. |
