1 GENERAL DESCRIPTION AND SPECIFICATIONS
The Model 10A60-4 is a general-purpose conditioner allowing input of up to four
external voltage signals. Mixed as desired, these may originate from DC-to-DC
LVDT’s, potentiometer-type sensors, and other 2-wire analog signal sources that
pro-
vide their own power supply.
Or they may represent the outputs of other instrument
systems having various voltage levels and grounding configurations.
Inputs can be either floating (differential) or grounded (single-ended). With differential
inputs, generous common-mode range and excellent common-mode rejection elimi-
nate ground-coupling errors and other problems normally associated with off-ground
signal sources. Chopper-stabilized DC amplification with active low-pass filtering
yields smooth and stable measurement of the true average value of the input variable,
even in the face of substantial dynamic content.

Transducer Types
: 2-wire DC voltage sources, grounded or floating
Input Voltage Ranges: ±0.5, 1.0, 2.0, 5.0, 10, or 20 V-DC; automatically selected—on
an individual channel basis—when the channel is configured; for the System 10
channel “type” codes assigned to 10A60-4 data channels, see Table 1, below
Amplifier (per channel):
Normal-Mode Range: ±20 V operating; ±200 V without instrument damage
Common-Mode Range: ±50 V operating; ±300 V without instrument damage
Common-Mode Rejection Ratio: DC: -60 dB; at 60 Hz: -70 dB
Input Impedance: Differential: 2 M; Common-Mode: 0.5 M
Offset: Initial: ±0.5 mV; vs. Temperature: ±0.005 mV/°C; vs. Time: ±0.05 mV/month
Gain Accuracy: ±0.02% of full scale typical, following calibration*
Gain Stability: vs. Temperature: ±50 ppm/°C; vs. Time: ±50 ppm/month
Filter (per channel): 3-pole modified Butterworth; 3 dB down at 10 Hz; 60 dB down at
100 Hz
Step-Response Settling Time (Full-Scale Output):
To 1% of final value: 150 msec
To 0.1% of final value: 200 msec
To 0.02% of final value: 250 msec
Auxiliary Outputs: Filtered outputs available on mainframe wire-wrap pins
* Initial (uncalibrated) inaccuracy may be as great as ±1.5% of full scale. Maximum error that
could occur upon replacement of a Model 10A60-4 not followed by calibration is ±3% of full
scale.

2 TRANSDUCER CONNECTIONS
The Model 10A60-4’s I/O CONNECTOR mates with Daytronic CONDITIONER CON-
NECTOR No. 60322, shown in Fig. 1.5 (in Manual Section 1.E.1). Table 2 gives stan-
dard pin assignments for the I/O Connector.
Cabling for
floating inputs is given in Fig. 1(a). NOTE: To minimize signal noise, it is
recommended that for a floating (ungrounded) input with high common-mode imped-
ance, the COMMON pin be tied to the –SIGNAL line at the connector. Cabling for
grounded inputs is shown in Fig. 1(b).
