NOVA PROCESS & TEMPERATURE CONTROLLERS

PD540 Series Temperature Controllers The PD540 is a 1/16 DIN 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 failsafe 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.	PD550 Series Ramp and Soak Controllers The PD550 is a 1/16 DIN Ramp & Soak Controller with auto-tuning PID control capabilities. Two programs store 15 segments each for precision set point control. At the completion of a program, the controller can hold the set point, stop the outputs, or loop to one of the programs, enabling one 30-segment program to be used. 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 failsafe operation. Digital input options add the ability of external contacts to operate the controller and digital output options are available. RS-485 serial communication options include protocols for Master/Slave set point control, Modbus ASCII and RTU, as well as PC software.
PD560 Series Digital Temperature Indicators The PD560 Series of meters combines excellent standard features including a universal input, alarm relay, and a 4 to 20 mA retransmitting output with powerful options including an additional two alarm relays, digital inputs, and RS-485 serial communication including Modbus.	PD570 Series Temperature Limit Controllers The PD570 Series of Limit Controllers come equipped with a limit control latching relay, alarm relay, and a 4-20 mA retransmitting output. These standard features make the Limit Controller an excellent process monitoring tool. Serial communications for Modbus or PC monitoring software expands the Limit Controller’s capability.
