The PD540 is a 1/16 DIN Nova Digital Temperature Controller with auto-tuning PID control capabilities. One of four user programmable set points may be selected for PID control in the form of time proportional relay on/off output, time proportional voltage pulse, or 4-20 mA signal control. Its universal input accepts 23 input varieties, including thermocouple, RTD, and voltage inputs and can be easily configured for a 4-20 mA input. The relays may be programmed as alarms with 20 different high, low, and deviation alarm types that can include fail-safe operation. Digital input options add the ability of external contacts to operate the controller. RS-485 serial communication options include protocols for Master/Slave set point control, Modbus ASCII and RTU, as well as PC software.
