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.
