Control type:
Supports multiple control modes (such as temperature, pressure, flow PID control).
Optional switch quantity (ON/OFF) or analog quantity (4-20mA/0-10V) control.
Input signal:
Compatible with thermocouples (J/K/T type), RTD (PT100), analog signal (0-10V/4-20mA).
Output signal:
Relay output (3A/250V AC, used to drive contactors, solenoid valves, etc.).
Optional analog output (such as 4-20mA for external display or PLC communication).
Display and operation
Human-machine interface:
Backlit LCD display, displaying real-time parameters (such as set value, actual value, alarm status).
Key programming or knob adjustment (convenient parameter setting).
Alarm function:
Configurable high and low limit alarms, relay output alarm signals.
