2.4 P OWER S UPPLY R EQUIREMENTS
For best performance, a regulated DC power supply that provides a nominal 24 VDC and at least 50 mA should be
used.
Important: Pay particular attention to the power supply for susceptibility to the effects of conducted and radiated
energy from noise sources. Every effort should be made to provide stable voltage to the amplifier using correct wiring
practices and filters. To protect against circuit damage, include a 0.25 Amp fuse in the power supply output lead to
each amplifier in case of amplifier or power supply malfunction.
The power source for the power supply shall be fused at the proper rating to prevent over current in
the supply leads due to a power supply failure.
Output voltage from the supply should be within +/- 10% of 24 VDC. Component stress due to excessive supply
voltage may damage components and prolonged operation with a higher than necessary voltage will increase the
internal temperature of the circuitry within the ISC. Supply voltages that are excessively low (either due to a low
supply set-point or excessive IR drop of voltage arising by long cable runs) can result in “brown-out” of internal
regulated supply voltages. This “brown-out” may be evident by the +/- 10V analog output being clipped at some
voltage below 10V. Keep in mind that voltage drops due to long cable runs may drop the voltage by nearly a half a
Volt (250 feet of 24 AWG cable carrying 30 mA will loose 0.4 V).
Although the amplifier provides limited galvanic isolation between the 24 VDC supply circuit and the strain-gage
amplifier circuit, it is only intended as a mechanism to avoid “ground loop” interference. The 24 VDC supply should
always have its output return referenced to P.E. (protective earth), so that uncontrolled potentials are not imposed
between the 24 VDC supply circuit and the load cell case.
For optimum performance, the DC supply voltage should be free from excessive ripple voltage or transient excursions.
2.4.1I NTERFACE WIRING
The load in this connection may be an indicator, recorder, data acquisition device or the analog input terminals of a
control device such as a DC drive or a programmable logic controller. The output signal at this terminal is undamped
and provides a direct response to changes in the transducer (load-cell) load. Note that the cable’s shield drain wire
should be connected at only one end, preferably at the “receiving end” (i.e. common ground at the PLC Analog Input
etc.).
The pair of wires associated with the amplified transducer signal are generally separated out from the 24VDC supply
wires at the point where they get routed toward the tension controller.
For most M12, DC keyed molded cordsets, the wire colors associated with the #1 and #3 pins is BRN and BLU
respectively.
For most M12, DC keyed molded cordsets, the wire colors associated with the #2 and #4 pins are WHT and BLK
respectively. These WHT and BLK wires provide the amplified tension signal transmitted as a +/- 10 VDC Full Scale
