Specifications

Operating ambient temperature	0 to 55℃
Storage ambient temperature	-25 to 75℃
Operating ambient humidity	5 to 95%RH (no condensation)
Storage ambient humidity	5 to 95%RH (no condensation)
Vibration resistance: Criterion	Shown in IEC61131-2.
Vibration resistance: When intermittent vibration is present: Frequency: 10 to 57 Hz	Half amplitude: 0.075mm Number of sweep times: 10 times in each of the X, Y and Z directions (for 80 min)
Vibration resistance: When intermittent vibration is present: Frequency: 57 to 150 Hz	Acceleration: 9.8 m/s 2 Number of sweep times: 10 times in each of the X, Y and Z directions (for 80 min)
Vibration resistance: When continuous vibration is present: Frequency: 10 to 57 Hz	Half amplitude: 0.035 mm Number of sweep times: 10 times in each of the X, Y and Z directions (for 80 min)
Vibration resistance: When continuous vibration is present: Frequency: 57 to 150 Hz	Acceleration: 4.9 m/s 2 Number of sweep times: 10 times in each of the X, Y and Z directions (for 80 min)
Shock resistance	147 m/s 2 , 3 times in each of X, Y, and Z directions The criterion is shown in IEC61131-2.
Working atmosphere	Corrosive gas shall not be present.
Operating altitude	2,000 m or less The module cannot be used in an environment pressurized above atmospheric pressure at the altitude of 0 m. If the module is used in such an environment, it may fail.
Installation location	Inside control panel Use in an environment other than inside a control panel is possible as long as the operating ambient temperature and humidity conditions are satisfied.
Over-voltage category	II or less This category indicates in which area (inside the site) in relation to the public wiring net the equipment is to be connected. Category II applies, for example, to equipment whose power is supplied from a fixed facility. The surge-resistant voltage of equipment rated 300 V is 2,500 V.
Pollution degree	2 or less This index indicates the degree of conductive substances generated in the environment in which the module is used. The degree of contamination 2 indicates that contamination is caused by the generation of only non-conductive substances, however, temporary conduction may be caused by accidental condensation.
