Brookfield Temperature Controller, Model 106 - Manual (Page 7)

Brookfield Engineering Labs., Inc. Page 7 Manual No. M/02-207-C009
For example, the temperature corresponding to a reading of 2.5 V (2500 mV) would be calcu-
lated as follows:
(0.1 x 2500) - 100 = 150°C or (0.18 x 2500) - 148 = 302°F
The recorder jack is a standard 1/4” phono jack. An optional analog output cable (Brookfield
Part No. HT-88Y) is available from Brookfield.
IV.3 Comm Port
The COMMUNICATION PORT provides an RS-232C data link to an external device such as a
computer or remote terminal. The RS-232C pin assignments are:
RS-232C PIN CONNECTIONS
Pin Number Function
2 Data Out (Tx)
3 Data In (Rx)
7 Ground (Gnd)
13 and 25 Remote Mode
Table IV.1
NOTE: Pin number 13 should be connected to pin 25 on the connector being inserted into the
Comm Port in order to place the Programmable Temperature Controller in the Remote
mode (indicated by the lit
REMOTE LED on the instrument front panel).

IV.4 AC, Power Switch and Power Fuse
The primary power requirement for the Programmable Temperature Controller can range from 85
to 265 VAC; 50/60 Hz and must be connected through the power cord. The voltage for which the
unit has been configured will be indicated on the bottom of the Programmable Temperature Con-
troller. The power consumption at 120 VAC is 400 ma plus the Thermo Container load power.
The power fuse must be a 2A/250V Littlefuse, fast acting type, GMA series or equivalent. This
fuse protects the controller electronics only.
