The PID111 is 1/32 DIN panel-mount PID Controller with a panel cut out of 1.77 x 0.88″, and the depth behind the panel is approximately 84mm.
Start with auto-tuning if your controller supports it, or tune manually by adjusting proportional gain, the integral term, and the derivative term while watching the system response. Classic methods include the Ziegler-Nichols method, the Cohen-Coon method, and the relay method.
PI control uses proportional and integral terms to correct error and eliminate steady-state error. PID control adds derivative action, which responds to the rate of change of error to help reduce overshoot and improve stability. However, derivative action can amplify measurement noise and is not beneficial for every process.
A PID controller compares the process variable (the measured value) to the set point (the desired value) to calculate the error. It then uses proportional, integral, and derivative calculations to determine the appropriate control output. This signal adjusts a control element, such as a valve or motor, while sensor feedback allows the controller to continuously monitor the process and correct deviations from the set point.
Maple Systems PID100 Series controllers are CE certified, cULus listed, and comply with RoHS and REACH requirements. They also meet EMC standard EN61326:
The Maple Systems PID100 Series support multiple sensors and process input types for PID temperature and process control applications.
Choose the PID111s when panel space is limited and the additional PID114 features are not required. Choose the PID114 when your application needs heater monitoring, remote set point capability, or the larger display format.
Yes, select Maple Systems PID100 Series controllers include built-in RS-485 communication and support Modbus RTU in slave mode.
The PID114 is a 9/64 DIN panel-mount PID Controller with a panel cutout of 68 x 68 mm., and the depth behind the panel is approximately 50 mm
