J1-8
SHLD DRN
Cable shield
drain terminal Cable Shield for LCH and RCH
transducer cables
Connect only at amplifier
Transducers (load cells) use strain gages which have limited insulation levels to ground (earth).
This requires that the COM terminals be connected to ground (earth) to prevent damage to the
transducers (load cells).

Supply Terminal Function Description Notes
J2-1 24V RET Power Supply Power supply return
Must not exceed 50 volts
from P.E.
J2-2 +24 VDC Power Supply Positive supply source
+20 to +28 VDC
@ 180 mA max
A fuse with a rating of 0.38A must be used in the 24 VDC supply lead to limit potential damage
to the amplifier in the event of circuit malfunction.
