Technical Specifications of the 140DRA84000

Output Configuration

In terms of output configuration, the Schneider Electric 140DRA84000 features 16 discrete outputs. Each output uses a Form A contact configuration. More precisely, the contacts are 1 NO (normally open) type. Regarding addressing, the module requires only 1 output word for all 16 points. Consequently, the module efficiently uses the Quantum backplane addressing space.

Voltage and Current Ratings

For AC applications, the discrete output voltage range is 20 to 250 V AC. For standard DC applications, it supports 30 to 150 V DC. Additionally, low-voltage DC from 5 to 30 V DC is also supported. Across all voltage ranges, the minimum load requirement is 50 mA.

The maximum load current, however, depends heavily on the load type. For resistive loads at 140°F (60°C), the module handles 2 A at 250/30 V AC/DC. For tungsten loads, the maximum is 1 A at 250/30 V AC/DC. Similarly, for motor loads (1/8 hp at cos φ = 0.4), it also handles 1 A at 250/30 V AC/DC. For resistive loads at 30 to 50 V DC, the rating is 300 mA. The surge current rating reaches 10 A for 10 ms (capacitive load). Furthermore, the switching capacity is 500 VA for resistive loads.

Response Time and Protection

Regarding response time, the maximum from state 0 to state 1 is 10 ms. Conversely, the response time from state 1 to state 0 is 20 ms. Therefore, this module suits applications with moderate switching speed requirements.

The Schneider Electric 140DRA84000 includes robust internal overvoltage protection. Specifically, a varistor rated at 275 V protects each output channel. In terms of isolation, the module provides 1780 Vrms AC between channels for 1 minute. Additionally, isolation between channels and the bus is also 1780 Vrms AC for 1 minute (or 2500 V DC for 1 minute).

Durability Ratings

For mechanical durability, the module achieves 10,000,000 cycles. When considering electrical durability, performance varies significantly by load condition. At 2 A for 30 V DC resistive loads, it achieves 100,000 cycles. At 2 A for 250 V AC resistive loads, it achieves 200,000 cycles. For 300 mA at 30 to 150 V DC resistive loads, it reaches 100,000 cycles. At 500 mA for 30 to 150 V DC resistive loads, it achieves 50,000 cycles. For 100 mA at 30 to 150 V DC with L/R = 10 ms, it reaches 100,000 cycles. Finally, when driving an interposing relay at 30 to 150 V DC, it also achieves 100,000 cycles.

Power and Signaling

In terms of power dissipation, the module consumes 5.5 W plus an additional 0.5 W for each active output point. As a result, maximum dissipation with all 16 outputs energized reaches 13.5 W. The bus current requirement is 1100 mA for the Quantum backplane.

Regarding local signaling, the Schneider Electric 140DRA84000 includes comprehensive LED indicators. One green LED shows that bus communication is active (Active). One red LED indicates that an external fault has been detected (F). Additionally, sixteen green LEDs show the real-time status of each individual output channel.

Environmental and Certification Specifications

The Schneider Electric 140DRA84000 holds several important certifications. These include FM Class 1 Division 2 for hazardous locations. Additionally, it carries C-tick, GOST, and ABS certifications for global deployment. The module also complies with UL 508 and CSA C22.2 No 142 standards.

Environmental Resistance

For electromagnetic compatibility, the resistance to electrostatic discharge is 4 kV contact per IEC 801-2. On air, it withstands 8 kV per the same standard. Furthermore, the resistance to electromagnetic fields is 9.1 V/m (10 V/m) from 80 to 2000 MHz per IEC 801-3.

Temperature and Humidity

The ambient air temperature for operation ranges from 32°F to 140°F (0°C to 60°C). For storage conditions, the range extends from -40°F to 185°F (-40°C to 85°C). The relative humidity tolerance is 95% without condensation. Consequently, the Schneider Electric 140DRA84000 operates reliably across various industrial environments. Regarding altitude, the maximum operating height is 5000 meters (16,404 feet).

Physical Specifications

The module format is standard for Quantum backplane compatibility. Additionally, the Schneider Electric 140DRA84000 carries CE marking for European compliance. The net weight is 0.41 kg (0.90 lbs). For shipping purposes, the package weight is 545 g (19.2 oz). The package dimensions are 31.2 x 4.5 x 16.3 cm.

Installation Guidelines for the 140DRA84000

First, mount the Schneider Electric 140DRA84000 in a standard Quantum backplane. After that, connect field wiring to the appropriate output terminals. Importantly, always observe the maximum current ratings for each specific load type. For inductive loads, use external suppression devices to significantly extend contact life. Then, configure the addressing as one output word in your application software. Finally, monitor the LED indicators for proper operation and any fault detection.
