12.2 Optional specifications
Alarm 2 (Option code: A2)
The alarm action point is set by the
deviation from the SV (except Process alarm).
[When the alarm action is set as Energized]
When the input goes outside the range, the output turns ON or OFF (in the case
of High/Low limit range alarm).
[When the alarm action is set as De-energized]
The output acts conversely.
One alarm can be selected by Rotary switch and DIP switch from 13 types of alarm
plus Pattern end output: High limit alarm, Low limit alarm, High/Low limits alarm,
High/Low limit range alarm, Process high alarm and Process low alarm, the standby
function which is applied to them respectively, as well as No alarm and Pattern end
output.
When Alarm 2 (A2 option) and Loop break alarm (LA option) are added together,
they utilize common output terminals.
If Alarm 2 (A2 option) is added, Heating/Cooling control (DR, DS, DA option) or
Insulated power output (P24 option) cannot be added together.
Setting accuracy : The same as Indication accuracy
Action : ON/OFF action
Hysteresis : Thermocouple, RTD input: 0.1 to 100.0
( )
DC input: 1 to 1000 (The placement of the decimal point
follows the selection.)
Output : Relay contact, 1a
Control capacity, 3A 250V AC (resistive load)
1A 250V AC (inductive load cos
=0.4)
Electrical life: 100,000 cycles
Alarm 3, Alarm 4 (Option code: SA)
The alarm action point is set by the
deviation from the SV (except Process alarm).
[When the alarm action is set as Energized]
When the input goes outside the range, the output turns ON or OFF (in the
case of High/Low limit range alarm).
[When the alarm action is set as De-energized]
The output acts conversely.
Alarm 3 and Alarm 4 are selectable by keypad from 13 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, the standby function
which is applied to them respectively, as well as No alarm.
Setting accuracy : The same as Indication accuracy
Action : ON/OFF action
Hysteresis : Thermocouple, RTD input: 0.1 to 100.0
( )
DC input: 1 to 1000 (The placement of the decimal point
follows the selection.)
Output : Relay contact 1a x 2
Control capacity, 3A 250V AC (resistive load)
1A 250V AC (inductive load cos
=0.4)
(However, A3 and A4 common terminal, maximum 3A)
Electrical life: 100,000 cycles
