Key Features

The 140AIO33000 provides eight intrinsically safe analog outputs for hazardous area control. For example, the 4 to 20 mA range suits most industrial transmitters and positioners. Meanwhile, the 0 to 20 mA and 0 to 25 mA ranges offer additional flexibility for specialized devices.

Accuracy is exceptional on this module. Specifically, absolute accuracy reaches ±0.2% of full scale at 25°C. Likewise, accuracy drift is only 40 ppm/°C (maximum 70 ppm/°C). As a result, output signals remain stable across wide temperature variations.

Response time is remarkably fast. For instance, update time is just 4 ms for all eight channels. Similarly, setting time reaches ±0.1% of final value within 1 ms. Consequently, this module suits high-speed analog control applications.

Intrinsic safety compliance allows direct connection to hazardous area devices. The module carries ATEX II1 G/D-EEx ia IIC certification for Zone 0, 1, and 2 gas environments. Additionally, FM Class 1 Division 1 Groups A, B, C certification covers North American hazardous locations. The SIRA 02ATEX2345X certificate number provides traceable compliance.

Internal fuse protection prevents damage from output overloads. The module also detects open circuit conditions on 4 to 20 mA loops. However, hot swapping is not permitted per intrinsic safety standards. Therefore, power must be removed before installing or removing this module.

1780 Vrms AC isolation between channels and the bus ensures operator safety. This high isolation voltage prevents hazardous energy from reaching the control room. The module also conforms to EN 50020 and EN 50014 for electrical apparatus in explosive atmospheres.

Installation Guidelines

To install the 140AIO33000, first remove power from the Quantum rack. Then insert the module into a standard Quantum slot. After that, push firmly until it seats completely in the backplane. Secure the module with the retaining screws.

Connect field devices using approved intrinsically safe wiring methods. Maintain proper segregation between intrinsically safe and non-intrinsically safe circuits. For 4 to 20 mA loops, ensure load resistance does not exceed 500 Ohms. Above all, follow ATEX or FM installation requirements for your specific hazardous area.

Configure the module using Concept V2.2 (or higher), ProWORX, or Unity Pro software. Select the appropriate output range for each channel. Set the output scaling to match your field device requirements. Finally, apply power and verify output signals with a calibrated current meter.
