Single Loop Controller With Relays iTRON

The iTRON controller series comprises universal and freely programmable compact instruments for a variety of control tasks. It consists of five models, with the bezel sizes 96mm x 96mm, 96mmx 48mm in portrait and landscape format, 48mm x 48mm and 48mm x 24mm.
The controllers feature a clearly readable 7-segment display which, depending on the version, is 10 or 20 mm high, for process value and set point 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-optimization, 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-set point controllers with a limit comparator, or as double-set point controllers. The linearizations 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.
