11.2 Optional Specifications
Event input
BCS2: EIW, EIT, EI options
BCR2/BCD2: C5W, EIW,
EIT, EI options
2 points of Event input (1 point for EIT option) can be applied.
Any Event selected in [Event input DI1/DI2 allocation] will be performed
depending on the DI1/DI2 input ON (Closed) or OFF (Open) status.
Circuit current when Closed: Approx. 16 mA
Event output
(EV2 option)
Output will be turned ON or OFF depending on the event conditions
selected in [Event output EV2 allocation].
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
Minimum applicable load: 10 mA 5 V DC
Heater burnout alarm
(C5W, EIW, W options)
Monitors heater current with CT (current transformer), and detects burnout.
EV1/EV2 output, for which Heater burnout alarm is selected in [Event output
EV1/EV2 allocation], will be turned ON or OFF.
This alarm is also activated when the input is burnt out.
Rated current: 20 A, 100 A (Must be specified when ordering.)
Single-phase: Detects burnout with CT1 input.
3-phase: Detects burnout with CT1 and CT2 inputs.
Setting accuracy: Within 5% of the rated value
Heating/Cooling control
(DS, DA, EV2 options)
Performs Heating/Cooling control.
(Specifications of Heating side are the same as those of OUT1.)
OUT2 proportional band:
Thermocouple, RTD inputs without decimal point: 0 to Input span
Thermocouple, RTD inputs with decimal point: 0.0 to Input span
DC voltage, current inputs: 0.0 to 1000.0%
OUT2 integral time: Same as that of OUT1.
OUT2 derivative time: Same as that of OUT1.
OUT2 proportional cycle: 0.5, or 1 or 120 seconds
Overlap/Dead band setting range:
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 ( )
DC voltage, current inputs: 1 to 10000 (The placement of the decimal point
follows the selection.)
OUT2 high limit: 0 to 100% (Direct current: -5 to 105%)
OUT2 low limit: 0 to 100% (Direct current: -5 to 105%)
OUT2 cooling method:
One cooling method can be selected from Air cooling (linear
characteristics), Oil cooling (1.5th power of the linear characteristics)
and Water cooling (2nd power of the linear characteristics) by keypad
operation.
