Scheme for connecting the single relay to
THRESHOLDS
connection output
:
The
THRESHOLDS
connection contains transoptor outputs of open collector type,
with load capacity 50mA / 24V.
The relays inputs must be protected with diodes, e.g. 1N4148.
The balance producer offers ready electronic PCB MS3K/P, which contains
RM96P relays with input voltage DC24V and output: AC 250V, 3A.
Important notes:
1.
After switching the balance on, both thresholds are set as maximum values.
2.
When selecting upper threshold value, pay attention that its value is not lower
than the lower threshold value.
3. Selecting lower and upper threshold
value is also possible by sending proper
commands from computer (for more information look into scale manual)
