C310
Wall- / Pipe-mount universal process controller
2 DS/C310–EN Rev. LC310
The C310 wall / pipe-mount universal process controller is a
highly versatile single-loop controller packaged in a robust field mounting housing.
No need to fit an expensive instrument panel when installing or
upgrading process equipment. The C310 can be rapidly
commissioned by simply fixing it to any flat surface or pipe and
making the electrical connections via the cable entry glands on
the underside of the unit.
The instrument has extensive control and i/o capabilities fitted
as standard, allowing it to be rapidly configured for almost any
application.
With IP66/NEMA4X water/dust protection the C310 can be
mounted right next to your process, no matter how harsh the
environment.

PID control
The C310's isolated analog output provides the standard control
output to I/P converters, thyristors etc. Alternatively, built-in relays can
be used to generate a time-proportioning control output.
Solid state relay SSR
A 12V time-proportioning logic output on the standard C310 can be
used to drive solid state relays (SSRs).
Valve position
The C310 is fitted with twin relays and a valve-position input for
closed-loop control of a motorized valve. 'Boundless' control (without
position feedback) and analog control (using 4 to 20mA output) are
also available in the standard unit.
Heat / Cool
Heat/cool control strategies may be implemented on the standard
C310, using a combination of the analog control output and one relay.
Ramp / Soak set point profiles
The standard ramp/soak facility provides 30 segments, freely
assignable amongst 9 programs. A Segment Event function enables
relays to be switched on or off at predetermined points within the
program.
Serial communications
Not only does the C310 provide clear process information in the field, it
can also communicate plant data to control rooms via an RS485 link,
using Modbus protocol.
