Event output (Option code: A5)
EVT4 and EVT5 are available.
The output will be turned ON or OFF depending on the conditions selected in [Event
output allocation].
Output
Relay contact, 1a
Control capacity: 3 A 250 V AC (Resistive load)
1 A 250 V AC (Inductive load, cos =0.4)
Electric life: 100,000 cycles
Heater burnout alarm (including sensor burnout alarm) [Option code: W, W3]
Output will be turned ON or OFF depending on the conditions selected in [Event
output allocation].
This alarm is also activated when indication is overscale and underscale.
This option cannot be applied to direct current output type.
Rated current
One type can be selected from the following.
Single-phase 20 A, Single-phase 100 A
3-phase 20 A, 3-phase 100 A
Single-phase: Detects burnout with CT1 input.
3-phase: Detects burnout with CT1 and CT2 input.
Setting range 0.0 to 20.0 A (for Heater rated current 20 A) (Off when set to 0.0)
0.0 to 100.0 A (for Heater rated current 100 A) (Off when set to 0.0)

Same as that of OUT1.
OUT2 deriva-
tive time
Same as that of OUT1.
OUT2 propor-
tional cycle
1 to 120 seconds [Factory default: Relay contact (DR): 30 seconds,
Non-contact voltage (DS): 3 sec, Direct current (DA): Not available]
Overlap/Dead
band
Thermocouple, RTD inputs: -200.0 to 200.0 ( )
DC voltage, current inputs: -2000 to 2000 (The placement of the
decimal point follows the selection.)
OUT2 ON/OFF
hysteresis
Thermocouple, RTD inputs: 0.1 to 1000.0 ( ) (Default: 1.0 )
DC voltage, current inputs: 1 to 10000 (The placement of the decimal
point follows the selection.)
OUT2 high limit 0 to 100%, [DA (Direct current): -5 to 105%] (Factory default: 100%)
OUT2 low limit 0 to 100%, [DA (Direct current): -5 to 105%] (Factory default: 0%)
