- 01 / 06Laumas CLM8i board only
CLM8i: the naked CLM8 board for building into your own enclosure.
The Laumas CLM8i (SKU 23116) is the naked, board-only version of the CLM8 intelligent junction box: eight independent load-cell channels with digital equalization, load distribution analysis and automatic diagnostics, a backlit LCD with a 4-key keyboard, and RS485/RS232 communication.

The datasheet shows the CLM8 in a weighbridge system: load cells feeding the CLM8, which connects to a W series indicator, database, printer and remote display (p.2). As a multi-channel junction box it is also used on:
01Truck scales and weighbridges
Reads every load cell separately and shows the load distribution across them.
02Tank, hopper and silo weighing
Multi-cell vessel weighing with per-cell diagnostics.
03Platform and floor scales
Digital equalization replaces trimpot adjustment of the corners.
04Service and troubleshooting
Per-channel readings (in mV) and fault reporting help locate a bad cell or cable.
03 / 06VersionBoard only, no enclosure.
The datasheet describes the CLM8i as the “naked version, board only”, 151 × 72 × 30 mm (p.1). It has no enclosure and the datasheet states no IP rating for it; the IP67 ratings in the datasheet belong to the boxed versions. Install the board inside a protective enclosure, panel or junction box suited to the environment.
01Naked board
Board only: no box, no fixing base. Overall size 151 × 72 × 30 mm.
02No IP rating stated
The datasheet gives no ingress protection for the board. Protect it with a suitable enclosure.
03Other CLM8 versions
Need a mounting solution that is ready to use? The same CLM8 is also available on a DIN rail (SKU 23114), in an IP67 stainless steel box (SKU 23117) or in an IP67 polycarbonate box (SKU 23128).
04 / 06What the CLM8 doesIntelligent functions on every version.
01Digital equalization
Place a sample weight at each load cell and the 8 channels are equalized digitally in one step, free of drift over time.
02Load distribution analysis
Shows the load percentage on each active channel, with an archive to store, consult and print.
03Automatic diagnostics
Detailed diagnostics of each load cell (max. 8) and immediate reporting of anomalies, including on a connected weight indicator.
04Communication
RS485 and RS232 with ModBus RTU, ASCII Laumas or continuous one-way transmission. Up to 32 instruments on one RS485 line (99 with repeaters).
05Tilt compensation (optional)
With an optional inclinometer (not included) the weight is corrected for tilt up to ±10°.
06Event archive
Stores the last 50 significant events: zeroing, calibration, equalization and alarms.

Product Order code Laumas CLM8i — board only, no enclosure 23116 Does the CLM8i include an enclosure?
No. It is the naked, board-only version. It has no enclosure and no IP rating is stated, so it must be installed in a suitable protective enclosure.
Which size is the board?
151 × 72 × 30 mm.
What is the working temperature for legal-for-trade use?
-10 to +40 °C for type-approved instruments (OIML R76:2006 class III, 3 x 10000 divisions). The general working range is -20 to +60 °C.
Is Ethernet included?
No. Ethernet TCP/IP is an option on request (OPZETTCPCLM); the standard ports are RS485 and RS232.
