(To detect Heater burnout, a CT for 50A can also be used for5A, 10A and 20A ratings, however, this is not suitable for small ampere ratings due to alow degree of accuracy. For a 20A rating or less, use a CT designated for 20A.)• When the Heater burnout alarm option is applied, one more option A2 output orHeating/Cooling control can be added.• This option cannot be applied to DC current output type.Heater rated current: 5A, 10A, 20A, 50A, Must be specifiedSetting accuracy : Within 5% of heater rated currentAction : ON/OFF actionOutput : Relay contact, 1aControl capacity, 3A 250V AC (resistive load)Electrical life, 100,000 cyclesHeating/Cooling controlWhen the Heating/Cooling control option is added, one more option A2 output orHeater burnout alarm can be added.OUT2 proportional band : 0.0 to 10.0 times OUT1 proportional band(ON/OFF action when set to 0.0)OUT2 integral time : The same as that of OUT1OUT2 derivative time : The same as that of OUT1OUT2 proportional cycle : 1 to 120 secondsOverlap band/Dead band :Thermocouple, RTD input: –100.0 to 100.0 ( )DC current, voltage input: –1000 to 1000 (The placement of the decimalpoint follows the selection)
