TLB4 RS485 Weight Transmitter

Laumas TLB4 RS485 weight transmitter

The Laumas TLB4 RS485 is made for weighing systems that use up to four load-cell inputs. Each channel can be viewed and balanced individually, which makes commissioning easier and helps identify an uneven load or a faulty sensor.

For control-system integration it uses RS485 serial communication for dependable, economical connection to compatible PLCs, displays and control equipment. Typical applications include vessel weighing, batching equipment and multi-cell platforms.

Relay outputs, digital inputs and an RS485 service connection are included for local functions and commissioning. Confirm the load-cell arrangement and RS485 network configuration when specifying the transmitter.
