Figure 2b: Typical 120 Vac for -B & -T Output

-F, -S Output - 120/240 Vac

The -F output is 20 mA at the low temperature end of the pro-

portional band and 4 mA at the upper end of the proportional

band. Maximum load resistance is 1000 ohms. The -S output

is a time-proportioned 20 Vdc signal. These controllers can-

not be used with a device that does not have an isolated

input. An ungrounded thermocouple must be used if there is

ac leakage or a ground in the input of the device connected

to the controller's output.
