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. To request more information, please fill the form below.
