Over 600 m Local 24 V supply to sensor at junction box is recommended
Although the signals on the cable are digital, it is recommended to avoid
electrically noisy areas such as pneumatics and generators.
The JB60CD electronic unit is mounted on the bridge. The Compact display is
supplied with 10 m of cable which can be extended to max. 20 m. This cable is
connected to the JB60CD electronic unit connector J300. The sensor cable is
connected to the JB60CD electronic unit connector J200. External inputs and
outputs are connected to the connectors J301 and J400 as shown in diagram
on next page ”JB60CD Interconnection Diagram” on page 18.
POWER
Power to the electronic unit (JB60CD) supplies power to the whole system.
The user has the option to use either or both AC 110-240 V, or DC 20-36
V supplies. Both can be connected at the same time. The JB60CD has
automatic fuses which, if tripped, will reset when the fault is removed.
THE DIGITAL INPUTS AND OUTPUTS
The digital inputs and outputs of the system meet the standard requirements
for IEC 61162-1. Inputs and pulse outputs are optoisolated as shown in
“JB60CD Connection methods” on page 20. To make these work, it is
necessary to apply a voltage and a resistance in series to the (XXXXX)A pin,
as shown. The nature of this type of connection is such that the installation
requires an external voltage (5-24 V) to function. A positive voltage is required
on pin marked (XXXXX)A. GND or negative on pin (XXXXX)B. Common alarm
output uses a standard relay are COM (8), NO (9), NC (10), on J400.
