Main features

Maximum 8 channel temperature control is possible in a 96mm square size

Two types; 4ch or 8ch

Panel space requirement is reduced

Maximum 8 types of memory areas

Up to 8 types of parameters of each channel can be registered. This contributes to improve efficiency of production lines and products management.

Parameters covered by Memory area:

Temperature setting, various Alarm setting, PID values, Anti-reset windup (ARW), Overlap/Deadband, Setting change rate limiter, Channel use/unuse

Abundant options

Communication function, alarm function, and digital contact inputs are available.
