1GENERALDESCRIPTIONANDSPECIFICATIONS

This single-channel, phase-encoded conditioner may be used with incremental

encoder sensors

whose outputs are quadratured to indicate “travel” and “direction of

travel,” for measurement of relative linear or angular displacements over a very wide

range of distances and precisions.

The 10A35 generates a count per 90°phase shift, with a maximum allowable count of

±32700 and a speed limitation of 50 kHz, maximum. To accommodate the largest num-

ber of transducers, this count may be predivided by any integer from 1 to 256, as

explained in Section 3.a. The 10A35 allows run-time “zero indexing” (resetting) and

restarting of a channel’s count reading by the operator or host computer. There are also

input provisions for a user-supplied auxiliary external power supply from 9 to 15 V-DC,

which would allow you to keep the count “alive” during system power shut-down.

NOTE: A System 10 data channel derived from a Model 10A35 always takes a channel

“type” code of

CA, and does not require calibration.

ADDITIONAL10A35 SPECIFICATIONS

input is available as a “TTLINPUT” or a “LOW-LEVELINPUT”

Excitation: Nominal 5 V-DC; 50 mA maximum

Accuracy: Based on transducer, ±1 digit

Auxiliary Power Supply: 9 to 15 V-DC

Auxiliary Outputs to Mainframe Wire-Wrap Pins:None

2TRANSDUCERCONNECTIONS

The Model 10A35’s I/O CONNECTOR mates with Daytronic CONDITIONERCONNEC-

TOR No. 60322, shown in Fig. 1.5 (in Manual Section 1.E.1). Standard cable connec-

tions—including connection of an optional “keep-alive” power supply—are given in Fig.

1, below. Table 1 gives standard pin assignments for the I/O Connector.

The 10A35 takes three input signals:

ZEROINDEX(RESET), PHASE 1 (SINE),and

PHASE 2 (COSINE). Each input is available as a “TTLINPUT” or a “LOW-LEVEL

INPUT.” With internal pull-up less than 1 LSTTLload, TTLINPUTS (Pins

3, C,and 5) are

for use with transducers with high output levels greater than 2.4 V-DC. With 15-kΩ

impedance, LOW-LEVELINPUTS (Pins

4, D,and E) are 200 mV minimum and 9 V

maximum without damage, and are for use with transducers with high output levels of

200 mV-DC to 2.4 V-DC. Low transducer output is less than 0.8 V-DC for TTL, and less

than 50 mV for LOW-LEVEL.
