Product Description The PID regulator has a precision of 0.2 level, a measurement and control speed of 10 times per second, and a display range of -1999 to 9999. Adopting advanced PID intelligent control algorithm, with anti overshoot function and self tuning (AT) function. Simulate universal input and select through settings. Please note ② Optional with 1 to 3 point alarm output. There are 10 basic alarm methods: upper limit (lower limit) of measured value, upper limit (lower limit) of deviation, upper limit (lower limit) of absolute deviation, upper limit (lower limit) of standby and upper limit (lower limit) of standby deviation. Optional communication or transmission function.
