5.3 General Specifications

Alarm

Criterion threshold can be set to either Hi or 

Lo.

Hi : The total at every sampling is judged 

within the interval.

Lo : The total is judged at every interval.

Alarm output

Alarm output × 2 CH

(Open collector: 30 VDC, 20 mAmax.)

Output is turned ON when an alarm (Hi or Lo) 

occurs.

Whether to hold the alarm output can be se-

lected. The reset switch or a command can 

be used to reset alarms.

Data deletion

All items of data are deleted by a command.

New data will be added to the previous data 

at the start of recording.

Power outage 

protection

After recovering from a power outage, the 

2304-20 automatically returns to the state 

held before the outage.

5.3 General Specifications

Clock accuracy

±100 ppm (Reference value at temperature 

from 0 to 50°C without the communications 

module)

Backup

Recorded data (saved in flash memory)

Data loss for up to 2 minutes before and after 

a power outage may occur.
