FUNCTIONS
●User function, easily programmable via the top panel
●Analogue output, RS 485 communication port and 1 Relay output
available
●Analogue output can be selected in 0~10V/0(4)~20mA
●Relay output for Hi / Lo energized with Start Delay / Hysteresis /
Energized & De-energized Delay / Relay Energized Hold….. functions
●RS 485 communication port available
EX：Low Cut is set for -0.01, if the display is ≤ -0.01,
and all the display will be 0.
Digital filter: seting range from 0(None)/1~99 times.
The digital filter can reduce the magnetic noise in field.
Digital Fine Adjustment: seting range from
-19999~+29999 ;Users can get Fine Adjustment by
front key of the converter, and “Just Key In” the value
which user want to show in the current input signals.
Maximum Hold or Minimum Hold:
The converter will keep display in maximum value
during power on until manual reset by front key in
【User Level】
Write to display by RS485 command
The display can be written by RS485 command. In
past, The converter nomorlly receive 4~20mA or
0~10V from AO card or BCD card of PLC. We support
a new solution by RS485 writing in so that can be
save cost and wiring into PLC.
Low Cut / Digital Filter / Digital Fine Adjustment
Low Cut: seting range from -5000~+5000 counts.
If the setting value is positive, it means the range of
absolute value will be 0; PV≤ Setting value, the
display will be 0;
EX：Low Cut is set for 0.10, if the display is from
-0.10~+0.10, that will be 0.
If the setting value is negative, it means the range of
under setting value will be 0; PV≤ -Setting value, the
display will be 0;
Hysteresis: Settable range from 0~9999 Counts
Relay energized delay: Settable range from
0.1(second)~9(minutes)59.9(seconds);
Relay de-energized delay: Settable range from
0.1(second)~9(minutes)59.9(seconds)
Relay energized mode Hi / Lo / Hi.HLd / Lo.HLd / DO
Hi:Relay will energize when PV > Set-Point
Lo:Relay will energize when PV < Set-Point
Hi.HLd (Lo.HLd): When the PV Higher (or lower) than
set-point, the relay will be energized and hold until
manual reset by from key in【User Level】.
