2 TRANSDUCER CONNECTIONS
The Model 10A10-4’s I/O CONNECTOR mates with Daytronic CONDITIONER CON-
NECTOR No. 60324, similar to the one shown in Fig. 1.5 (in Manual Section 1.E.1). This
connector contains four “±” screw-terminal pairs, one for each TC sensor. Each TC
lead should be directly attached to its corresponding screw terminal (it should never
be soldered). As shown in Fig. 1, each screw terminal connects internally to a specific
pin on the 10A10-4’s rear 20-pin I/O CONNECTOR. Table 2 gives standard pin assign-
ments for the I/O connector. For connection of an optional
Model 10CTJB-8 Thermo-
couple Junction Box
, see Section 4, below.
Since reference-junction compensation is provided by the dual-bead thermistor
embedded in the Conditioner Connector, no external cold junction is required.
IMPORTANT: UNUSED THERMOCOUPLE INPUT CHANNELS should be shorted
together as shown in Fig. 2, to prevent possible crosstalk from the “OPEN TC” detec-
tion circuit into working TC channels.
