ATR401 - multiiestatījumu kontrolieris ar 2-ām ieejām

Double Universal Input

All models are provided with 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 process 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.
