12-24VDC Operation

The General Purpose and the In-Panel Readouts will operate on 12-24VDC.
The General Purpose Readout uses a multi-purpose plug-in connector for
power as well as

input and output signals

The In-Panel Readout uses screw terminals for these connections.
Also,

See Section 3: Circuit Board Jumpers

General Purpose Readout

In-Panel Readout

When powering Readouts with 12-24VDC, the Scale and the Readout common
must be connected to each other, or connected to each other via a common
point. A proper connection will eliminate ground loops that may cause unstable
readings on the Readout.

NOTES: When using Model 150, 250 or 950 operated on 12-24VDC, use
only Scales, & Encoders with

part #’s end in ‘G’.

12-24VDC Readouts are designed to run on DC VOLTAGE ONLY.
