Digitron Italia S.r.l.
Model ATR 141 -Double Setpoint Temperature Controller
Controller 32x74mm, Single control loop, 4-digits Display. Distinctive feature is the high configurability, resulting in a limited number of ordering codes. Universal analogue input, selectable for a wide range of sensors, both for industrial or civil applications. Relay/SSR outputs, programmable as command/alarm/event. Optional RS485-ModbusRTU/Slave. User-friendly operation, programming tools for quick set-up (MEMORY-CARD, programming and monitoring software LABSOFTVIEW).
