All models accept two inputs,
configurable for temperature sensors
and linear signals, to manage a double
control loop( 1 PID/Tune and 1 ON/OFF)
or a single loop relating the two
processes to a mathematical operation
(addition, difference, mean). It is
possible to configure humidity
+ temperature sensors into a single
controller and show both process
variables on dual frontal display.
Additional input allows to set remote
set-point for cascade control, or by
an external potentiometer. TA input
for amperometric transformer and Loop
Break Alarm mode can be overlapped to input 2.
Selectable command and alarm outputs
Starting from the basic model with 2 relay outputs + SSR command up to 3 and 4 relays and the most complete version that includes 2 relays + SSR, analogue output Volt/mA and RS485+Modbus RTU/Slave. Wide configuration options for alarm logic, selectable as Absolute/Band/Deviation with and without any retaining or delay at starting.
Extended supply range and simplified configuration mode
Controller can accept supply power from 24 to 230Vac/Vdc, and generates a power supply of 24Vdc/30mA that can be used for two-wire linear sensors. Programming tools are available either on PC (Labsoftview) or by memory-card (with and without battery). Integrated Easy-up mode allows a simplified inputs and outputs configuration by entering preselected passwords.
