GIGASENSE – Electronic Unit 9:300 B

The PIAB 9:300B Electronic unit is mainly used together with one load cell / force transmitter in order to protect a lifting device against overload. It can also be used for other applications such as load indication. The PIAB 9:300B is very easy to install with screw terminal blocks and a back lit display. The unit is delivered programmed and adjusted to your required parameters from factory.

PIAB 9:300B function

The PIAB 9:300B can be used for connection to PIAB force transmitters and / or PIAB load cells (0 – 2mV/V). The signal from the force transmitter is processed and amplified by the programmable circuit board (PCB) of the electronic unit.The PIAB 9:300B has two relays and one analogue 4 – 20 mA signal output:

Relay 1
Limit 1 is used for warning or slack rope control.

Relay 2
Limit 2 is used for overload limitation and includes two set points: 2A and 2B. 2A has a possibility to set on- and off delay of the overload limit. 2B is used for a value that is greater than 2A and has no delay function.

4 – 20 mA
The analogue signal output can be used to transfer the load indication to your own system or to run a PIAB MICROBUS large format display.

PIAB 9:300B safety

The PIAB 9:300B Electronic Unit is self-checking. Any malfunction of load cell or cable will indicate overload. This informs the operator that the system is out of order.
