1 GENERAL DESCRIPTION AND SPECIFICATIONS
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.
ADDITIONAL 10A35 SPECIFICATIONS
Input Signals: ZERO INDEX (RESET), PHASE 1 (SINE), and PHASE 2 (COSINE); each
input is available as a “TTL INPUT” or a “LOW-LEVEL INPUT”
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
2 TRANSDUCER CONNECTIONS
The Model 10A35’s I/O CONNECTOR mates with Daytronic CONDITIONER CONNEC-
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:
ZERO INDEX (RESET), PHASE 1 (SINE), and
PHASE 2 (COSINE). Each input is available as a “TTL INPUT” or a “LOW-LEVEL
INPUT.” With internal pull-up less than 1 LSTTL load, TTL INPUTS (Pins
3, C, and 5) are
for use with transducers with high output levels greater than 2.4 V-DC. With 15-k
impedance, LOW-LEVEL INPUTS (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.

1.E.2.10A35
An excitation of +5 V-DC is provided by the 10A35, as shown in Fig. 1. If a higher exci-
tation level is required, the user must provide his or her own external supply, in which
case the 10A35's EXCITATION OUTPUT (Pin
1) should NOT be connected to the sen-
sor.
The 10A35 has input provisions for a user-supplied external power supply from 9 to 15
V-DC. This external (“Auxiliary”) supply would allow you to keep the count “alive” dur-
ing system power shut-down. The optional “keep-alive” supply should be connected
to Pins
A and 2, as shown in the figure.
ALSO NOTE: When Pin 5 (ZERO INDEX TTL INPUT) is not used, it must be tied to
COMMON (Pin
2).
