Control
Control action
• PID action (with auto-tuning function)
• PI action: When derivative time is set to 0
• PD action (with manual reset function): When integral time is set to 0
• P action (with manual reset function): When derivative and integral time are set to 0
• ON/OFF action: When proportional band is set to 0
OUT proportional band : 0.0 to 110.0% (ON/OFF action when set to 0.0)

Control output (OUT)
• Relay contact: 1a, Control capacity 3A 250V AC (Resistive load)
• Non-contact voltage (for SSR drive): 12
• DC current: 4 to 20mA DC, Load resistance; Max. 550
Output accuracy: Within

EVT output
• Alarm output
[Alarm, Loop break alarm and Heater burnout alarm (option) utilize common output terminals.]
The alarm action point is set by
and when input is out of the alarm setting range, alarm (EVT) turns ON or OFF (High/Low limit
range alarm). When Deenergized is selected in the Energized/Deenergized selection, alarm
(EVT) is activated conversely.
