Model D10096-000 Master Reference Unit is

designed t o han dle a var iety of applicat ions in

which signa l conditioning an d mu ltiple out put s

are r equired while maintaining input to output

circuit isolation. Each Model D10096-000 cansupply four separate outputs that are each iso-

lated from th e mast er reference signal and a lso

from each of th e oth er outpu ts. If more th an

four outp uts a re required, two or more un its

ma y be ganged togeth er.

A variety of output s are a cceptable as sources

for t he ma ster reference signal. A +10 VDC

voltage is available to allow the ma ster signal

to be sourced from a 2,000 to 10,000 Ohm, 2

Wat t potent iometer. The potent iometer signal is

supplied th rough a linear acceleration/decelera-

tion circuit with two selectable ran ges. A cus-

tomer-supplied cont act closur e ena bles the

acceleration/deceleration circuit and allows the

reference to accelerate to a level set by the

input potentiometer. Th e decelerat ion circuit

opera tes wh enever th e reference is lowered.

When t he ena ble contact opens, the r eference is

zeroed immed iat ely.

Four selectable volta ge ran ges may a lso be

used as master signals. The input impedance is

greater th an 1,000,000 Ohms for ea ch voltage

ra nge. The available input r an ges are 0 to 25

VDC, 0 to 50 VDC, 0 to 100 VDC an d 0 t o 200

VDC.

Three selectable current ranges are availableto ha ndle var ious process cont rol signa ls. The

appr oximate inpu t impeda nce for each ran ge is

listed in the chart below.

1 to 5 mA 1,000 Ohms

4 to 40 mA 270 Ohms

10 to 50 mA 100 Ohms

The fina l input is for a sine or squar e wave

with a frequency ra nge from 0 to 2,000 Hz. A

buffer circuit with an input impedance of

appr oximately 100,000 Ohms is supplied to

limit loading on the frequency source. The cir-

cuit switches at a threshold level of approxi-

mately 0.5 VDC.

Four ident ical output circuits are s our ced

from the ma ster signal. Each output h as sepa-

rate OFFSET, GAIN, and BIAS adjustments to

ta ilor th e output signal. An optional Trim

potentiometer input is also provided to allow

th e out put to be remotely rat ioed.

sent of an authorized Company representative, make a change in spec-ifications to products, parts or systems covered by a purchase orderaccepted by the Company. In the event of any such changes, theCompany shall be entitled to revise its price and delivery schedule undersuch order.

8. Returned materialIf the Purchaser desires to return any product or part, written autho-

rization thereof must first be obtained from the Company which willadvise the Purchaser of the credit to be allowed and restocking chargesto be paid in regard to such return. No product or part shall be returned
