Superior control with the PID simulator

Enhanced smart loader package

The model SLP-C1F_ _ _ smart loader package, which allows you to easily configure various settings, such as those for the PID simulator, is available free of charge. By connecting a PC to the controller using a USB loader cable (separately sold, model SLP-ULCJA0), you can read and write parameters from the PC using the loader.

PID simulator

The PID simulator assists in reducing overshoot and hunting. It helps you to reduce the time needed for trial run adjustment and to improve takt time and the quality of equipment.

Easy connection with PLC link function

Data is transmitted by RS-485 serial communication without the need for a communication program, saving you time and engineering work.

Supported protocol	Connectable model examples
Mitsubishi/QnA-compatible 3C frame model 4	MELSEC iQ-R, MELSEC Q
Omron FINS (host link)	CJ2, CP2
KEYENCE protocol mode 4	KV-7000/8000

Large, easy-to-read LCD screen

The large LCD screen can display a 4.5-digit number (−19999 to 19999). With the multi-status indicator, status can be seen at a glance, even from a distance.

Pullout structure for easy replacement

Quick recovery in the event of a sudden instrument failure. The pullout structure allows replacement of the inside of the instrument from the front without using special tools.
