The C Series can support a variety of options, including serial communications. Use of most of these options
requires that you confi gure a few parameters.which are arranged in menus, one for each option. The
available options include:
REMOTE SETPOINT - this option allows you to select either of two setpoints for your process. The second
setpoint can be enabled only by an external switch or signal. Parameters are set in the

menu.
AUXILLIARY OUTPUT
- this option allows the Setpoint Variable or Process Variable to be transmitted to a
remote device such as indicators, data recorders, computers, process controllers, etc. with 1 of 4 different
interfaces: 4-20 mA, 1-5 V, 0-20 mA, or 0-5 V. The output signal is scalable and multiple remote indicators
may be driven by the controller. (NOTE: current and voltage outputs cannot be used simultaneously.)
Parameters are set in the

menu.
ALARM - Two alarm outputs are available; the action of these outputs follows the action of the A1 and A2
front panel LEDs. Parameters are set in the

menu.
CONTACT / DIGITAL INPUT - can be used to trigger use of a second setpoint, or to toggle the controller’s mode
from normal to standby, or to toggle between running and holding a ramp/soak recipe. Parameters are set
in the

menu.
TRANSDUCER EXCITATION - a transducer excitation option is available to provide power to remote
transducers. There are no confi guration parameters associated with use of the transducer excitation output.
