Temperature alarm output
The alarm action point is set by ± deviation to the main setting (except Process value alarm).
[When the alarm action is set as energized]
When the input exceeds the range, the output turns ON or OFF
(in the case of High/Low limit range alarm).
[When the alarm action is set as deenergized]
The output acts conversely.
• Setting accuracy
Thermocouple : Within ±0.3% of input full scale ±1 digit, or ±2°C (4°F) whichever is greater
RTD
: Within ±0.2% of input full scale ±1 digit
• Action
: ON/OFF action
Hysteresis, 0.1 to 100.0°C (°F)
• Output
: Open collector
Control capacity, 24Vdc 0.1A (maximum)
Loop break alarm output
When manipulating value is in its maximum or minimum status, the alarm is activated if the
process variable does not change at a rate higher than the setting span within the setting time.
Detects Heater burnout, Sensor burnout and Abnormality at operation end.
Output: Open collector
Control capacity, 24Vdc 0.1A (maximum)
Control action
PID action (with auto-tuning function)
PD action (with auto-reset function) (When I value is set to 0.)
P action (with auto-reset function) (When I and D values are set to 0.)
ON/OFF action (When P value is set to 0 or 0.0.)
Proportional band : 0 (0.0) to rated scale maximum value
Integral time
: 0 to 3600s (off when set to 0)
Derivative time
: 0 to 3600s (off when set to 0)
Proportional cycle : 1 to 120s
ARW
: Automatic
Output limit
: 0 to 100% (For the Current output type, -5 to 105%)
Hysteresis
: 0.1 to 100.0°C (°F)
Circuit insulation configuration
* If the control output type is current or non-contact voltage output, between
the communication and output is non-isolated.
