- 01 / 06Laumas CLM8 DIN rail version
CLM8 for Omega/DIN rail: fits a back panel or your own junction box.
The Laumas CLM8 (SKU 23114) is the Omega/DIN rail 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 / 06VersionOmega/DIN rail mounting.
The datasheet describes this version as “Omega/DIN rail mounting version suitable for back panel or junction box”, 125 × 92 × 52 mm (p.1). It is supplied without an enclosure and the datasheet states no IP rating for it, so install it in a panel or box that suits the environment.
01Omega/DIN rail
Mounts on a standard Omega/DIN rail inside a back panel or junction box.
02Compact size
Overall size 125 × 92 × 52 mm.
03Other CLM8 versions
The same CLM8 is also available as a naked board (SKU 23116), 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 CLM8 — Omega/DIN rail version 23114 How is the DIN rail version mounted?
On an Omega/DIN rail, in a back panel or a junction box (125 × 92 × 52 mm).
Is it weatherproof?
The datasheet states no IP rating for the DIN rail version. For wet or dusty areas use the IP67 boxed versions (SKU 23117 or 23128) or install it in your own protective enclosure.
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.
