1 GENERAL DESCRIPTION AND SPECIFICATIONS
The Model 10A16-4C is designed for high-accuracy temperature measurement using
platinum
Resistance Temperature Detectors (RTD's). Precision constant-current
excitation is provided for four independent sensor channels, which may be intermixed
as required. RTD inputs are normally set for four-wire cabling, with maximum excita-
tion of one milliampere and input impedance of 10 MΩ, to eliminate common self-heat-
ing and cable-loading errors. However, for an RTD channel with shared current return
and sense signals, three-wire mode is available, if desired, via an internal jumper set-
ting (as explained in Section 3.a, below).
ADDITIONAL 10A16-4C SPECIFICATIONS
RTD Types: Platinum; DIN (European) standard with “ice-point” resistance of 50, 100,
or 200 ohms, or American standard with “ice-point” of 100 ohms
Range and Resolution: See Table 1, below; automatically selected—on an individual
channel basis—when the channel is configured; for System 10 channel “type” codes
assigned to 10A16-4C data channels, see Table 1; for
high RTD resolution, using a
specially modified 10A16-4C card, see Section 3.c, below

tion and processing): see Table 1, below
Auxiliary Outputs: Filtered outputs available on mainframe wire-wrap pins

2 TRANSDUCER CONNECTIONS
The Model 10A16-4C’s I/O CONNECTOR mates with Daytronic CONDITIONER CON-
NECTOR No. 60322, shown in Fig. 1.5 (in Manual Section 1.E.1). Standard
four-wire
RTD cabling is shown in Fig. 1(a), below. With separate excitation and sense lines, this
mode of cabling normally yields the highest measurement accuracy. However, any
10A16-4C input channel can be set to accommodate the alternative
three-wire cabling
shown in Fig. 1(b). THE APPROPRIATE JUMPER SETTING MUST BE MADE FOR EACH
10A16-4C CHANNEL, DEPENDING ON WHETHER 4-WIRE OR 3-WIRE CABLING IS
BEING USED FOR THAT CHANNEL (see the instructions in Section 3.a, below). Table 2
gives standard pin assignments for the I/O Connector.
IMPORTANT: When cabling the 10A16-4C, you can ensure static protection by con-
necting the SHIELD wire to
Pin 10 as well as to the connector ground lug, as shown in
Fig. 1.
