Frequently Asked Questions (FAQs)
What does “explosion proof” mean in this context?
“Explosion proof” means the enclosure and construction are designed so that any internal explosion (due to sparks or faults) cannot propagate to the external hazardous atmosphere. It prevents ignition of gases or dust outside the unit.
What input signals does AUTC48F support?
The AUTC48F supports universal input types: 4-20 mA, 0-5 V DC, PT100 (Resistance Temperature Detector – RTD), and thermocouples (types J, K, R, S).
Does AUTC48F offer output options?
Yes. It provides a 4-20 mA analog output. In addition, it has two 3 A relay outputs (1CO each) configurable via front key for heat or cool control actions.
Can I calibrate or configure the device in the field?
Yes. The AUTC48F supports front-key calibration and configuration, allowing you to set input type, output scaling, relay behavior (heat/cool), etc., directly on the device.
What is the power supply requirement?
The device uses an SMPS (Switched Mode Power Supply) and operates on 90–260 VAC at 50 Hz.
What materials and enclosures are available?
The transmitter is supplied in flameproof (explosion-proof) enclosures, made of aluminum. Two different flameproof enclosure models are available.
What is the switching (relay) capacity?
The relays are rated at 3 A (resistive load). The unit has two relays (1CO configuration).
In which applications or industries is this transmitter commonly used?
Typical applications include chemical plants, oil & gas, petrochemical, HVAC systems, industrial ovens, process control lines, etc., wherever accurate temperature measurement and control in hazardous areas is needed. (This is inferred based on device class and features.)
