Microprocessor controller, format 48x48 (1/16 DIN) manufactured using SMT.
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.
The main input for the process variable is universal and provides the possibility to connect many types of input sensor: thermocouple type J, K, R, S, T, B, E, N, Ni-Ni18Mo, L; resistance thermometer Pt100 3-wires; thermistor PTC; linear inputs 0-50mV, 10-50mV, 2-10V, 0-10V, 0-20mA, 4-20mA, and potentiometer, all with the possibility of custom linearisation that can be defined using the faceplate keys.
It is possible to activate correction of the input using a linear function defined by way of two points on it.
The type of input is selected from the faceplate keys and no external shunts or adapter are required.
A second auxiliary isolated analogue input is available, which can also be configured for a linear input (0-10V, 2-10V, 0-20mA / 4-20mA), for remote setpoint, potentiometer or current transformer.
The auxiliary input function is completely configurable, including the possibility of a custom linearization. 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.
The instrument can have up to 4 relay (3A/250V) or logic (12Vdc, 20mA)
