描述：The PID500MH-0000 is a 4-digit auto-tuning Temperature Controller with up to 3 outputs which are designed for control of temperature or processes in a wide range of industrial applications. The controller operate from a range of thermocouple or 2/3 wire PT100 (RTD) input sensors or from a milli-volt, 0 to 5VDC, 0 to 10VDC or 0/4 to 20mA process signal. This version is available with relay, SSR or analogue outputs which can be configured as 1 ON/OFF or PID control and up to 2 alarm outputs or as 2 ON/OFF or PID controls (heat/cool) and 1 alarm output. The temperature controller is housed in a compact DIN48 square enclosure which can either panel mount or surface/DIN rail mount to a socket and is auxiliary powered from either 24VAC/DC or 85 to 270VAC. . Dual display of set point and process value . 1 or 2, On/Off or PID control outputs . Auto-tuning of PID parameters . Reverse or direct action . Up to 3 relay or SSR outputs . Alarm output . Thermocouple, RTD and analogue inputs . Single point ramp and soak facility . 24VAC/DC or 85 to 270VAC powered
