Standard Function
A1 output,
A2 output,
A3 output
The alarm action point can be set at random (process alarm), and if the input
reaches the randomly set action point, the alarm output turns ON or OFF
corresponding to the alarm type and Energized/De-energized selection.
The alarm type can be selected from; No alarm action, High limit alarm, Low limit
alarm, High limit with standby alarm, Low limit with standby alarm and High/Low
limit range alarm (for A3 output only).
High/Low limit range alarm can be selected when A1 High limit alarm (High limit
with standby alarm) and A2 Low limit alarm (Low limit with standby alarm) are
combined, or when A1 Low limit alarm (Low limit with standby alarm) and A2
High limit alarm (High limit with standby alarm) are combined.

decimal point follows the selection.)
Alarm
HOLD
function
Enables/Disables the Alarm HOLD function.
If Alarm HOLD function is set to “Enabled”, and if the alarm is ON,
the alarm output ON status will be maintained until the following is
conducted.
• The FAST key is pressed for approx. 3 seconds.
• The power is turned OFF.
• The HOLD is cancelled by the Event input function.
During Alarm HOLD, corresponding alarm action indicator flashes.
Output
Relay contact 1a
Control capacity: 3 A 250 V AC (resistive load)
Electrical life: 100,000 cycles
Transmission
output 1
Converting the PV to analog signal every 125 ms, outputs the value in direct
current. (Unaffected by the HOLD function) (When using the Transmission output 1
value as an input for other instruments, check that the input impedance of these
instruments is smaller than the maximum load resistance of Transmission output 1.)
