Allowable voltage

fluctuation

85 to 264 V AC, 20 to 28 V AC/DC

Power consumption Approx. 9 VA

Ambient temperature -5 to 55

Ambient humidity 35 to 85%RH (non-condensing)

Weight Approx. 200g (socket included)

Mounting DIN rail

External dimensions W30 x H88 x D108mm (socket included)

Attached Functions

Auto-light function Automatically measures and controls brightness of the displays

to conserve power.

Power failure

countermeasure

The setting data is backed up in the non-volatile IC memory.

Self-diagnosis The CPU is monitored by a watchdog timer, and if an abnormal

status is found on the CPU, the instrument is switched to

warm-up status, turning all outputs OFF.

Cold junction

temperature

compensation

Available only for the SE2EA and SE1EA.

This detects the temperature at the connecting terminal between

the thermocouple and the instrument, and always maintains it at

the same status as if the reference junction location temperature

was at 0 (32 ).
