- Product overview:
-
Analog signals from the connected devices such as sensors can be
converted to signals suitable for a programmable controller (example:
from a temperature signal to a voltage signal).
Data from sensors can be visualized easily, and small-scale IoT can be
introduced.
- Merit.1
- This module converts a resistance CT input into a voltage output. (Isolation between input and output is provided.)
- Merit.2
- The module can be mounted/removed to/from an installation base unit easily.

| Storage ambient humidity | 5 to 95%RH, no condensation | |
| Vibration resistance ( With intermittent vibration ) | 5 to 8.4Hz : Half amplitude 3.5mm | |
| 8.4 to 150Hz : Acceleration 9.8m/s2 | ||
| Number of sweeps : 10 times in each direction X, Y, and Z | ||
| Vibration resistance ( With continual vibration ) | 5 to 8.4Hz : Half amplitude 1.75mm | |
| 8.4 to 150Hz : Acceleration 4.9m/s2 | ||
| Shock resistance | 147m/s2, 3 times in each direction X, Y, and Z(Applicable standards : JIS B 3502, IEC61131-2) | |
| Operating atmosphere | Free of corrosive gases | |
| Operating altitude *1 | 2000m or less | |
| Installation location | Inside the control panel *4 | |
| Overvoltage category *2 | II or less | |
| Pollution degree *3 | 2 or less | |
| Precautions | *1 Do not use or store the module under pressure higher than the atmospheric pressure at an altitude of 0 meters. Doing so may cause malfunction. When using the module under pressure, please consult your local Mitsubishi Electric representative. |
|
| *2 This indicates the assumption that the equipment is connected to a power distribution system, ranging from a public electrical power distribution network down to machinery within the premises. Category II applies to equipment for which electrical power is supplied from fixed facilities. The surge voltage withstand level for equipment with the rated voltage of up to 300V is 2500V. | ||
| *3 This index indicates the degree to which conductive material is generated in terms of the environment in which the equipment is used. In pollution degree 2, only nonconductive pollution occurs. A temporary conductivity caused by condensation must be expected occasionally. |
||
| *4：The enclosure is suitably designed for those specific environmental conditions, as applicable, and enclosure rate meets IP20 and minimum type 1 of UL 50. | ||
