The JUMO iTRON series of compact process controllers provides users with a large, legible display, 1 universal and 1 logic input, from 1 to 3 output relays, and several power supply options (14VDC, 24V AC/DC, 110 – 240V AC) in an affordable package. Features include standard PID auto-tune, a ramp function, 8 kinds of limit monitors, and a timer function.
There are five designs with:
96mm x 96mm
96mm x 48mm portrait
48mm x 48mm
48mm x 24mm landscape
The controllers feature a clearly readable 7-segment display which, depending on the version,
is 10 or 20 mm high, for process value and setpoint indication or for dialogs. Only
three keys are needed for configuration. Parameter setting is arranged dynamically, and
after two operation-free seconds the value is accepted automatically. Self-optimisation,
which is provided as standard, establishes the optimum controller parameters by a key
stroke. The basic version also includes a ramp function with adjustable gradients. A timer
function has been integrated as an extra.
All controllers can be employed as single-setpoint controllers with a limit comparator, or
as double-setpoint controllers. The linearisations of the usual transducers are stored. Protection
is IP65 at the front and IP20 at the back. The electrical connection is by a plug-in
connector with screw terminals.
