Controller

DATA SHEET

With front dimensions of 48×48mm, this socket type tem perature controller enables On- Off control, PID control or 8-step ramp/soak function, using thermocouple, resistance bulb or DC1 to 5V signal as input.

Though small-sized, it can be equipped with a variet y of functions.

FEATURES

1. PID with auto-tuning, PID self-tuning and fuzzy control are installed as standard.

2. Front side waterproof speciﬁcation in conformity with NEMA4X (standard).

3. Two alarms are equipped, and 8-step ramp/soak function can be installed as an option.
