Dimensions
Getting Started
1.) Using a small screwdriver, ball point pen, etc.set the four switches on
the side of the unit (see Input Programming and Output Programming
on page 2).
2.) Mount unit into panel. (see Mounting on page 3).
3.) Connect unit to input signal, output signal, and power wiring (see Wir-
ing on page 4).
4.) Check calibration (See Calibration on page 4).
Specifications are on page 4.

Output Programming
MODE SELECTION SWITCH BANK (SW-3)
1. ForVOLTAGE OUTPUT turn switches one and two ON and switch
three OFF.
2. For CURRENT OUTPUT turn switches one and two OFF and
switch three ON.
3. For UNIPOLAR OUTPUT turn switch four ON and switch five OFF.
4. For BIPOLAR OUTPUT turn switch four OFF and switch five ON.
5. For ZERO BASED OUTPUT (eg. 0TO 20 mA) turn switch six ON
and switch seven OFF.
6. For ZERO SUPPRESSION (eg. 4 TO 20 mA) turn switch six OFF
and switch seven ON. If BIPOLAR is selected, do not use the
ZERO SUPPRESSION switch. Use the ZERO adjustment to sup-
press the output.
7. Switch eight is always OFF. (It is not connected to any circuitry. If
switch eight is turned ON there is no effect on the operation of the
device.)

WARNING: Do not attempt to operate this de-
vice with the cover removed. Potentially le-
thal voltage is present on some of the internal
components. Do not open the unit. There are
no internal adjustments or user serviceable
parts in the unit.
Mounting
Mount the unit in a panel on an industry standard 35 mm DIN rail. An
optional surface mounting kit is available from the factory (P/N
35DINADPTR).
To install, hold the SC468 so that the front is higher than the rear. Place
the upper slot on the rear of the SC468 on the top edge of the DIN rail.
Slowly rotate the front down until the bottom spring clip snaps over the
bottom edge of the DIN rail.
To remove from the DIN rail, place a small slotted screwdriver in
the slot in the spring clip under the housing. Pry the slot down-
ward to release the SC468 from the bottom of the rail.

Wiring
The wiring terminals for the SC468/SCL468 are compression
type. To open the wiring terminal, turn the screw for that
terminal counterclockwise. Slide the wire into the terminal
space. While holding the wire in place, turn the screw
clockwisetotighten. Thewireshould be held snugly in place.
Power for the SC468 is 85 to 265 Vdc/Vac 50 to 400 Hz.
Power for SCL468 is 12 to 28 Vdc/Vac 50 to 400 Hz.
Wire the input, output, and power as shown on the wiring
label. For AC current input, install a jumper wire be-
tween terminals 7 and 8.
Do not run Class 2 signal wires adjacent to or in the
same conduit as power wires.
Calibration
1. Apply the appropriate input for the low end of the scale.
2. Adjust the ZERO screw for the appropriate low end output.
3. Apply the appropriate input for the high end of the scale.
4. Adjust the SPAN screw for the appropriate high end output.
5. Repeat as necessary.
