The Nova PD540 is a digital temperature controller with auto-tuning PID capabilities that is available in 1/16, 3/16, 1/8, and 1/4 DIN sizes. Models include standard one-directional control (i.e. heating or cooling) or bi-directional heating and cooling control. 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 output, or 4-20 mA signal control. Its universal input accepts 23 input varieties, including thermocouple, RTD, and voltage inputs, and it can be easily configured for a 4-20 mA input. It is available with up to three (3) relays, two (2) 4-20 mA analog outputs, two (2) digital inputs, and an RS485 serial communication option which includes protocols for master/slave set point control, Modbus® ASCII and RTU, as well as PC software.

Reverse Operation (Fail-Safe): Programmable, independent for each alarm. Relay coils are energized in non-alarm condition. In case of power failure, relays will go to alarm state.
Forward Operation: Relay coils are energized in alarm condition. In case of power failure, relays will go to non-alarm state.
Auto Alarm Initialization: Normal and standby operation independent for each alarm. Normal alarms will reflect the state of the input to the controller at all times. Standby alarms will not trigger if the change to alarm state is a result of power up cycle, set point change, or alarm configuration change.
Run Status: Relays will energize when PID outputs are running.
