12.2 Optional specifications
Alarm 2 output [2AS or 2AL]
The alarm action point is set by ±deviation to 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.
One of the alarms can be selected by rotary switch and DIP switch from 14 types
of alarm: High limit alarm, Low limit alarm, High/Low limits alarm, High/Low limit
range alarm, Process high alarm and Process low alarm and the standby function
is applied to them respectively, as well as No alarm and Pattern end output.
When Alarm 2 output and Loop break alarm output are applied together [2AL],
the output terminal is common.
Alarm 2 output (A2) is not available with a combination of Heating/Cooling
control output [D 2] or Insulated power output [P24].
Setting accuracy : Within ±0.2 % of input range full scale ±1digit
Action
: ON/OFF action
Hysteresis setting range
When thermocouple or RTD input, 0.1 … 100.0 °C (°F)
When DC input, 1 … 1000 (Decimal point place follows the selection.)
Output : Relay contact 1a
Control capacity, 250 V AC, 3 A (resistive load)
250 V AC, 1 A (inductive load cosø=0.4)
Loop break alarm output [2AR or 2AL]
Detects the breaking status on the loop such as heater burnout, sensor burnout or
the operation end trouble.
When Loop break alarm output and Alarm 2 output are applied together [2AL],
the output terminal is common.
Loop break alarm output (LA) is not available with a combination of
Heating/Cooling control output [D 2] or Insulated power output [P24].
Output Relay contact 1a
Control capacity, 250 V AC, 3 A (resistive load)
250 V AC, 1 A (inductive load, cosø=0.4)
