Features
|
|
|
|
The 2416
is a versatile, high stability, temperature or process controller,
|
|
|
· High stability control
|
with self and adaptive tuning, in a 1/16 DIN size (48 x 48 x
150mm).
|
|
|
· Up to four 16
|
It has a
modular hardware construction which will accept up to three
|
|
|
segment programs
|
plug-in I/O modules and one communication module. The 2416 is
fully
|
|
|
· Heating & Cooling
|
configurable on-site.
|
|
|
· Motorised Valve
|
The 2416
is also available in versions with a simple 8 segment setpoint

provided to set up the initial PID values

|
and to calculate the overshoot
inhibition parameters. In addition an

|
Universal
input
|
|
|
· Auto/manual button
|
A universal input circuit with an advanced analogue to digital convertor
|
|
|
· Setpoint rate limit
|
samples the input at 9 Hz and continuously
corrects it for drift. This
|
|
|
· DC retransmission
|
gives high stability and rapid response to
process changes. High noise
|
|
|
· PDSIO setpoint input
|
immunity is achieved by rejection of 50/60 Hz pick-up and other
|
|
|
or retransmission
|
sources of noise.Sensor
diagnostics are also provided. The input will
|
|
|
· Digital communications
|
accept standard thermocouples, the Pt100 resistance thermometer
and

|
|
· Plug-in from front
|
linear millivolts,
milliamps or DC volts. Input filtering from OFF to 999.9

|
Access to

|
be customized
to present only those parameters that need to be
|
|
|
|
viewed or adjusted. All other parameters are locked away under
|
|
|
|
password protection. A front panel auto/ manual button is
provided.
|
|
|
|
Alarms
|
|
|
|
Up to four process alarms can be combined onto a single output.
They
|
|
|
|
can be full scale high or low, deviation from setpoint, rate of change or
|
|
|
|
load failure alarms. Alarm messages are
flashed on the main display.
|
|
|
|
Alarms can be configured as latching or non-latching and also
as
|
|
|
|
‘blocking’ type alarms, this means that they will become active
only
|
|
|
|
after they have first entered a safe state.
|
|

Available with either EIA485 2 wire or 4 wire
or EIA232. With industry-

|
|
|

including: Modbus®, Eurotherm
Bisync, and SPI.
