212/212X Installation & Technical
8200-M639-O1 Rev D 09/14
Optically Isolated Inputs
The 212/212X has four programmable inputs that may be used to
remotely initiate various functions within the indicator. These inputs are
accessed via a terminal block (P3) on the back of the PC board. See
Figure No. 13 for the connector location and input labels. Note that the
DFC feature defines terminal 1 as Start and terminal 2 as Pause.
NOTE: The input must be connected to COM to initiate the function.
Optically Isolated Outputs
(Requires additional hardware)
Preset Weight Comparator Logic Level Output
If desired, you may use the optically isolated outputs from your 212/212X
indicators’ preset weight comparators to remotely (up to 100 feet) control
peripheral devices used to manage the flow of material or signal when the
weight is within preset limits.
J7 (VP/VCC) – REMOTE OUT SRC (SOURCE) JUMPER
The Remote Output SRC jumper J7, when connected, allows the
212/212X indicator to supply (source) VP (15VDC) or VCC (5vdc) to a
solid-state relay or other load of 200 ohms or greater. The positive
connection from the relays must be connected to the PWC connector
negative wire from the relays to the GND pin. See Figure No. 13 for
jumper and REMOTE OUTPUT connector location.
For completely isolated outputs, J7 must be open (positioned on one plug-
in pin only or removed) and the user must provide 12 to 24 VDC to the
SRC pin and a ground return to the load. The load must still be 200 ohms
or greater.
