Model 335 Temperature Controller
This section provides a description of the Model 335 rear panel connections. The rear
panel consists of the Input A and B sensor input connectors (#1 in FIGURE 3-1), Out-
put 2 voltage output and relays 1 and 2 terminal block connector (2), USB B-type con-
nector (3), IEEE-488 interface connector (4), line input assembly (5), Output 1 and 2
heater output connectors (6 and 7), and the thermocouple option inputs (8). Refer to
section 8.10 for rear panel connector pin-out details.
Always turn off the instrument before making any rear panel connections. This is espe-
cially critical when making sensor to instrument connections.
This section describes how to properly connect the Model 335 to line power. Please
follow these instructions carefully to ensure proper operation of the instrument and
the safety of operators.
FIGURE 3-2 Line input assembly
The Model 335 has four different AC line voltage configurations so that it can be oper-
ated from line power anywhere in the world. The nominal voltage and voltage range
of each configuration is shown below. (The recommended setting for 230 V operation
is 240 V.)
Nominal Minimum
100 V 90 V
120 V 108 V
220 V 198 V
240 V 216 V
