REAR TERMINAL CONNECTIONS
Terminals 11 & 15 are not used.
Count Inputs
Terminal#2 is the connectionforInput A, whichisprogrammable to be
the rate channel and total. Terminal #1 is the connection for Input B,
whichisprogrammabletobeanincrementinginput,adecrementing
input, or channel B of encoder input. Input B cannot be used for rate - it
onlyservesasa secondary input fortotal. Thecommonconnectionfor
both Input A and Input B is Terminal #3.
Control/Digital Inputs
Acontact closureorNPN signalcanbeusedtoactivatepreconfigured
functionality. Terminal# 5 is usedforaremote resetfunction,while
Terminal#6isasecurityfunction,thatwhenactive,willprohibitentry
into Program Mode. Terminal #8 serves as the common for both of these
inputs.
Auxiliary Power Output
A 9 - 15 VDC for powering external sensors and encoders up to 125 mA
canbeaccessedbyconnectingthepositivesupply side of the sensor to
Terminal#4andthe negative side to Terminal#8.
Linear Output
Anoptionboardmaybe installed thatprovides a 10bitlinear output
signal relative to the Rate Value. Terminal #12 is the positive side of the
connection,andTerminal#10isthenegative side. The default range of
the output is 4-20 mA, but can be changed via the front panel to 0-20
mA, 0-10 VDC, 2-10 VDC, 0-5 VDC, or 1-5 VDC.
Input Power
Foran AC poweredunit, Terminal #13 serves as the line
or Hot side connection for AC powered units and as the
positiveside for DCpoweredunits. The neutral sidefor
ACpoweredunitsand the negative sideforDCpowered
unitsareconnectedtoTerminal#14.
Transistor Outputs
Yourunitcomesstandard with 2 NPN outputs which areactivatedby
each of the alarms. Transistor Output 1, which is tied to the High Alarm
Value, is on Terminal #7. Transistor Output 2, which is tied to the Low
Alarm Value, is on Terminal #9. Terminal #8 serves as the common
connectionforbothtransistoroutputs.
Relay Outputs
Yourunit comesstandard with arelay output which is tied to the High
Alarm Value. Terminal #19 is NC, Terminal #20 is common, and
Terminal #21 is NO. A second relay output tied to the Low Alarm Value
can be added as an option at the time of order or later installed in the
field.Terminal#22 is NC, Terminal#23 is common,and Terminal #24 is
NO.
Serial Communication
AnRS-485communicationboard,utilizingASCIIprotocol,canbe
installed as an option. Terminals #16 & #17 serve as the B and A
connectionsrespectively,whileTerminal#18isconnectedasthe
common.
