DESCRIPTION
The S12 display is designed to be a window into programmable controllers. Working with any 12
to 24 VDC PLC output card, it accepts full parallel or strobed data from the controller. It can
display values such as temperature, setpoints, time, speed or other data within the controller.
This keeps the operator aware of important parameters. The 4 or 6 digit S12 display is mounted in
a 1/8 DIN housing and has .56” red-orange, 7 segment displays. The S12 receives data full
parallel, 4 lines per digit, or may be switch selected to receive all data on 4 binary inputs directed
by individual digit strobe lines. Decimal position, positive or negative logic, two different display
codes as well as input filtering are selectable by switches behind the removable front lens. Any
number of displays can be linked together using the optional ribbon cable and strobe lines.
SPECIFICATIONS
DISPLAY: High efficiency 0.56 inch, 7 segment LED
POWER: 12 VDC -10% to 24VDC +10% , Current: 175 mA maximum
DISPLAY CODES: Two "Display codes", switch selectable:
Hexadecimal (H) code displays 0-9, A-F
B (B) code displays 0-9, -, E, H, L, P, (blank)
INPUT MODE: Data can be entered full parallel (24 lines for 6 digits). Several displays can be
linked together using the optional parallel ribbon cable. By connecting together the 6 digit
strobes of each display, each display can be updated by its separate strobe bank. Change a
dipswitch and you can enter all data over 4 data lines by strobing the 6 individual strobe lines.
The minimum strobe pulse is 1 msec. but the S12 can be set by dip switch to react only to
longer pulses. This prevents data from being entered by noise signals. If the strobe input is
held at "Display Update" voltage level, the display changes as data changes.
NOTE: The display is centered on 4 digit units. Display data and strobes are connected to
terminals for the 4 inside digits.
DECIMAL POINT: Dipswitch selectable in any position or none.
INPUTS (Binary data and strobes):
VOLTAGE: High: Greater than 75% of supply voltage.
Low: Less than 50% of supply voltage.
IMPEDANCE: 4.7K Ohm to ground.
NOTE: INPUT TYPE 4 (last digit of part number) has 4.7K Ohm to +DC supply voltage. Inputs
not connected will be in a "High state". Inputs must be driven low by a "Sinking" driver.
Use only with output modules that sink to ground.
POLARITY: (Dipswitch selectable) Unit accepts either positive or negative true data.
TEMPERATURE: Operating +32 F (0 C) to + 130 F (+54 C).
Storage: -40 F (-40 C) to +200 F (+93 C).
TERMINATIONS: "X”: 32 contact socket screw terminal accepts wire up to #12 AWG. "X" adapter
also has connector for ribbon cable hook-up of multiple displays. (Ribbon cable ordered
separately.)

STROBE INPUT
The strobe input controls data entry into the display. It is used to latch the data or enable the
display to be updated by new data inputs. The polarity of the strobe is set by SW2. Minimum
strobe pulse is 1 mSec. The S12 can be set by SW7 and SW8 to react only to longer pulses, thus
preventing data from being entered by noise signals. If the strobe is held at " Display Update"
voltage level, the display changes as the data changes.
PARALLEL DATA INPUT
Data can be entered full parallel (24 lines for 6 digits). When driving a single display, strobe inputs
do not need to be connected if
A: S12 has INPUT TYPE 1 and SW 1 is ON
B: S12 has INPUT TYPE 4 and SW 1 is open
Otherwise, connect all strobes together and jumper to ground (to + DC power If negative polarity
is selected). The display will change as data changes. Several displays can be linked together
with the optional ribbon cable that connects data and power to every display in the link. Connect
the digit strobes together for each display. Connect the strobe bank for each display to an output
driver programmed to be normally high (Normally low If negative true polarity). When data on the
parallel ribbon needs to be displayed, activate the selected display strobe bank for the time set on
switches 7 and 8 to update that display. Data must be constant at least 2 mSec. before and after
the strobe is returned to the latch voltage level.
Once the strobe is returned to the "latch "voltage level, new date can be generated on the parallel
ribbon cable and a new display updated by activating its strobe.
MULTIPLEX DATA INPUT
If SW 1 is open, all data is entered in a multiplex fashion on 4 lines only (TB-1 pins 7, 8, 9, 10).
The strobe lines must be normally high (normally low for negative true polarity). Activate digit
strobes one at a time to latch each digit as data is sent for that digit. (Digit 1 is LSD, digit 6 is
MSD.) Data must be constant at Ieast 2 mSec. before and after the strobe returns to the latch
voltage level. Any number of displays can use the same 4-wire data bus using individual strobes
to update each digit of each display.
DIP SWITCH SELECTION
The S12 Display is designed with several switch selectable options, which are set by the end
user. New units are normally shipped with switches 2 and 6 in the ON (down) position and 3, 4, 5,
7 and 8 in the Open (up) position. If changes are needed, locate the switches behind the front
lens. To remove the lens, locate the two screws on both sides of the unit. The switches are
located at the lower right (see below). To replace the lens, insert the front bezel and insert the two
screws.

MOUNTING INSTRUCTIONS
The S12 is mounted in a 3.662” by 1.772" panel cutout - The screw terminal adapter and the 2 side mounting
brackets must be removed so that the S12 may be inserted through the panel cutout. After the unit is inserted into
the panel place the two side brackets into the side grooves. Insert the two #8 screws through the back of the side
brackets and tighten until the front of the brackets are tight against the back of the panel. Plug the terminal adapter
onto the back of the unit. Put the fiber washers on the #4 screws. Insert each screw in turn through the corner holes
of the terminal and one of the spacers and tighten into the plastic housing.
