Microprocessor controller for three-step motorized valves, 48x96 / 96x96 (1/8DIN - 1/4DIN) size.

Manufactured using SM Technology, the instrument provides a complete operator interface, protected by a Lexan membrane that ensures level IP65 faceplate protection.

It has 4 keys, two green LED displays, each with 4 digits, 4 red indicating LED's for the 4 logic or relay outputs, and a further 3 LED's that are programmable to indicate the various operational states of the instrument. 10 led red bargraph indication can be associated with analogue outputs for control, inputs, deviations or valve position.

The main input for the process variable is universal and provides the possibility to connect many types of input sensor: thermocouple, resistance thermometer, thermistor, linear inputs, potentiometer, all with the possibility of custom linearisation that can be defined using the faceplate keys.

The type of input is selected from the faceplate keys and no external shunts or adapter are required.

It is possible to activate correction of the input using a linear function defined by way of two points on it.

A second auxiliary isolated analogue input is available, which can also be configured for a linear input or, potentiometer for valve position feedback.

It is possible to configure the 2 available isolated digital inputs for selection of up to 4 local setpoints; start, stop and reset of internal timer; Auto/Man, Loc/Rem functions; alarms memory reset; input hold function.

This instrument has up to 4 relè (3A, 250V) or logic (12Vdc, 20mA) outputs, 2 of which will be dedicated to the open/close valve function
