ORDERING INFORMATION
• Code number: 48NDVD-[1][2]-[3][4]
Specify a code from below for each [1] through [4].
(e.g. 48NDVD-42-R/CE/D/Q)
• Special input range (For codes Z & 0)
• Bargraph scale (e.g. 0 – 100 %) (See ‘Scale Plate.’)
• Digital indicator scale (e.g. 0.0 – 130.0)
• Specify the specification for option code /Q
(e.g. /SET)
[1] ALARM OUTPUT
0: None
2: 2 points
4: 4 points
/F: Bezels for Fuji Electric's PAJ, PAK, PBA panel cutout
Other Options
blank: none
/Q: Option other than the above (specify the specification)
SPECIFICATIONS OF OPTION: Q
EX-FACTORY SETTING
/SET: Preset according to the Ordering Information Sheet
(No. ESU-9436)
BEZEL OPTION
Bezels are used to adapt the 48N Series to an existing panel
cutout. In order to replace M-System’s 48 Series products,
use the one attached to the 48N Series as standard. When
the existing panel is cut according to DIN standard, specify
‘/D’ suffix code.
For a new installation, no bezel is required. Please refer to
‘Mounting Requirement’ and mount the 48N directly.
Ingress protection is invalid when the 48N is mounted with a
bezel, or when multiple modules are stacked side by side.
