• A contact/digital input can be used to trigger use of a second setpoint (see 1.6.4),

or to toggle the controller’s mode from normal to standby, or to toggle between

running and holding a ramp/soak recipe. The function of this input is selected

using the C-dIC-dI (contact/digital input) menu (see 14.8). For the 16C the

contact/digital input card is available with one dedicated alarm relay. The alarm

action is configured using the AlrAlr (alarm) menu

• An auxiliary analog output can be used to transmit the setpoint or the process

value. The function of this output is selected using the AoutAout (auxiliary output)

menu (see 14.7).

• A remote analog setpoint input can be used to provide the controller with a

setpoint from an external device.

This input is scaled using the parameters in

the rASrAS (remote analog setpoint) menu (see 14.9).

• A transducer excitation option is available to provide power to remote

transducers. There are no configuration parameters associated with use of the

transducer excitation output.

To see what options the controller in hand supports, compare the model number on the

controller’s label with the model number breakdown in the installation manual supplied

with the controller.

Use of the Remote Analog Setpoint is turned on and off by means of a contact on the RAS option card.
