DESCRIPTION

The T48 Controller accepts signals from a variety of temperature sensors

(thermocouple or RTD elements), precisely displays the process temperature,

and provides an accurate output control signal (time proportional or linear DC)

to maintain the process at the desired temperature. The controller’s

comprehensive yet simple programming allows it to meet a wide variety of

application requirements.

The controller operates in the PID control mode for both heating and cooling,

with on-demand auto-tune, which will establish the tuning constants. The PID

tuning constants may be fine-tuned by the operator at any time and then locked

out from further modification. The controller employs a unique overshoot

suppression feature, which allows the quickest response without excessive

overshoot. The unit can be transferred to operate in the manual mode, providing

the operator with direct control of the output. The controller may also be

programmed to operate in the ON/OFF control mode with adjustable hysteresis.

A second setpoint is available on select models to allow quick selection of a

different setpoint setting.

Dual 4-digit displays allow viewing of the process temperature and setpoint

simultaneously. Front panel indicators inform the operator of the controller and

output status. On many models the main control output and the alarm outputs

are field replaceable.

Optional alarm(s) can be configured to activate according to a variety of actions

(Absolute HI or LO, Deviation HI or LO, Band IN or OUT, and Heater Current

Break) with adjustable hysteresis. A standby feature suppresses the alarm during

power-up until the temperature stabilizes outside the alarm region. The second

alarm can be configured as a secondary PID output (heat/cool applications).

Optional Main Linear DC output (10 V or 20 mA) can be used for control or

temperature re-transmission purposes. Programmable output update time

reduces valve or actuator activity. The output range can be scaled independent

of the input range.

Optional Second Linear DC output (10 V or 20 mA) provides an independent

temperature re-transmission, while the main Linear DC output is being used for

control. The output range can be scaled independent of the input range.

Optional Heater Current Monitor provides a direct readout of process heater

current. An alarm can be programmed to signal when the heater has failed. This

provides early warning of system failure before product quality is affected.
