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:
Limit 1 is used for warning or slack rope control.
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.
- Transducer input:
0 – 2 mV/V.
- Operating voltage:
110 or 240 VAC.
- Working Temperature:
-20 to +70°C.
- Protection class:
IP 65 according to IEC 529 / NEMA 13.
- Switch Off Capacity:
8 A, 250 V AC
- Is designed for use in aggressive industrial environment. The individual printed circuit boards are mounted on chock absorbing devices. The electronic is mounted into a lockable steel box (protection class IP 65).
- The PIAB Electronic Units are self checking. Malfunction of system components (transducer, amplifier or cable) will indicate overload.
- All connections are made to terminal blocks -Earth connections (ground) for power supply and signals are separated (to avoid interference).
