• Push-button for calibration and sensor offset adjustment from the keypad.
• Built-in non-volatile memory to ensure that calibration and other information are not erased if power supply fails.
• Menu-driven program that simplifies set-up.
• Automatic temperture compensation (ATC)
• Manual temperature compensation setting without the ATC probe, with independent setting for calibration and process temperature.
• Two galvanically isolated current outputs 0/4-20mA.
• Two switching contacts as set-point relays.
• 0 to 2000 seconds time delay adjustment on all relays - minimizes false alarms
• Separately adjustable high and low set-point hysteresis (dead bands) prevent chattering of relays around the set points.
• Three control modes: limit controller, P controller and PI controller (P/PI controller as pulse length or pulse frequency).
• Large dual display LCD for easy reading with clear multiple annunciators, alarm status, operational and error messages.
• Separate alarm relay that alerts user to set point limits exceeded for a certain time and if the NTC300 thermistor wires are broken or disconnected during the ATC function
• Wash relay.
• Hold function to freeze output current (0/4-20mA) and release control relays
• LED indicators signal control activities to visually monitor transmitter status from a distance
• Protection against electromagnetic interference.
• Back lit and UV light protected LC display.
