ANALOG DEVICE FOR ANALOG OUTPUT TEMPERA-
TURE CONTROL — The analog controlled device selected
must be capable of receiving a 4 to 20 mA signal. Its internal
impedance must not exceed 600 ohms.
The power supply of the analog device must be field in-
stalled.
Using a 20 AWG twisted wire pair, wire the control signal
as follows (Fig. 51).
1. Connect the positive (
1
) contact to pin 46 of the option
module.
2. Connect the negative (−) contact to pin 47 of the option
module.
DEVICE UNDER DISCRETE OUTPUT TEMPERATURE
CONTROL — The factory-supplied SPDT relay must be field
installed and wired. See Fig. 52. The relay contacts are rated
as follows:
48 va at 24 vac and .25 power factor
125 va at 115 vac and .25 power factor
125 va at 230 vac and .25 power factor
The relay provides a set of contacts (normally open and nor-
mally closed) using no. 6 screw terminals while the 24 vdc
coil connections are through
1
⁄
4
-in. quick connects.
Using a 20 AWG twisted cable, connect the relay coil con-
tacts 1 and 2 to the option module pins 50 and 51. Connect
the device to be controlled to the normally-open or normally-
closed contacts of the relay. Pay close attention to the con-
tact ratings listed above. See Fig. 53.
DISCRETE OUTPUT DEVICE UNDER TIMECLOCK
CONTROL — The factory-supplied SPDT relay must be field
installed and wired. (Fig. 52.) The relay contacts are rated as
follows:
48 va at 24 vac and .25 power factor
125 va at 115 vac and .25 power factor
125 va at 230 vac and .25 power factor
The relay provides a set of contacts (normally open and nor-
mally closed) using no. 6 screw terminals while the 24 vdc
coil connections are through
1

-in. quick connects.
Using a 20 AWG twisted cable, connect the relay coil con-
tacts to the option module pins 53 and 54. Connect the de-
vice to be controlled to the normally-open or normally-
closed contacts of the relay. Pay close attention to the contact
ratings listed above. See Fig. 54.
