Product Overview

The Schneider Electric 140ACO02000 is an analog output module for the Modicon Quantum automation platform. This module provides 4 analog output channels with a 4 to 20 mA signal range. The 140ACO02000 uses 12-bit bipolar current conversion for precise control. Engineers use this module for valve positioning, actuator control, and analog signaling. Notably, the module carries FM Class 1 Division 2 and cUL certifications. Therefore, it suits hazardous location installations. The compact standard format fits easily into Quantum racks.

Technical Specifications

Analog Output Characteristics

The Schneider Electric 140ACO02000 offers 4 analog outputs in a single module. Each output delivers a 4 to 20 mA signal for standard process instruments. The addressing requirement uses 4 output words in the Quantum memory map. The analog output range maps 0 to 4096 counts for the 12-bit bipolar current. Therefore, you get fine resolution for precise control applications.

The absolute accuracy error at 25°C (77°F) is ±0.20% of full scale. Linearity stays within ±1 LSB for consistent performance. The accuracy drift with temperature is ±0.004% of full scale per °C typical. The maximum drift reaches ±0.007% of full scale per °C . Consequently, the module maintains accuracy across varying temperatures.

Response & Timing

The update time for all channels is 3 ms . The settling time reaches 900 µs to ±0.1% of the final value. Therefore, the 140ACO02000 responds quickly to setpoint changes. This fast response suits applications requiring rapid valve or actuator movement. The open circuit fault detection identifies broken 4 to 20 mA loops.

Isolation & Protection

Isolation between channels measures 500 V AC at 47 to 63 Hz. The module also withstands 750 V DC for 1 minute. Therefore, channel-to-channel interference stays very low. This isolation protects your control system from field wiring faults. The module also detects open circuit conditions on each output.

Power Requirements

The bus current requirement from the Quantum backplane is 480 mA. Maximum power dissipation reaches 5.3 W . The external power requirement ranges from 12 to 30 V DC . The loop voltage also uses 12 to 30 V DC . The maximum voltage drop stays below 30 V at 20 mA . Therefore, ensure your power supply meets these requirements.

Local Signaling & Diagnostics

The Schneider Electric 140ACO02000 includes multiple status LEDs. One green LED indicates bus communication is active. One red LED shows an external fault condition. Four green LEDs indicate each channel is turned on. Four red LEDs indicate a channel fault. Consequently, you can diagnose problems quickly without software tools.

Environmental Limits

The operating temperature ranges from 32°F to 140°F (0°C to 60°C) . Storage temperature extends from -40°F to 185°F (-40°C to 85°C) . Relative humidity tolerance reaches 95% without condensation . Operating altitude goes up to 5000 metres (16,404 feet) . Therefore, the 140ACO02000 suits most industrial environments.

Physical Dimensions & Weight

The module uses a standard format for Modicon Quantum racks. The net weight is 0.3 kg (0.7 lb) . The packaged weight reaches 457.0 g (16.1 oz) . Package dimensions are 4.8 cm height, 16.5 cm width, and 31.5 cm length. The country of origin is the United States (US) .

Standards & Certifications

The Schneider Electric 140ACO02000 complies with multiple standards. These include CSA C22.2 No 142 and UL 508 . Product certifications include FM Class 1 Division 2 and cUL . The module carries CE marking for European compliance. Resistance to electromagnetic fields reaches 10 V/m from 80 to 2000 MHz per IEC 801-3.

Installation Guide

Follow these steps to install the 140ACO02000 analog output module. First, power down the Modicon Quantum system completely. Second, select an empty slot in the Quantum rack. Third, align the module with the top and bottom guides. Fourth, slide the module into the slot until fully seated.

Fifth, secure the module with the retaining screws at top and bottom. Sixth, connect the external 12 to 30 V DC power supply to the appropriate terminals. Seventh, wire your field devices to the 4 output channels. Use shielded twisted pair cable for best noise immunity. Eighth, configure the output ranges in your control software. Map the 4 output words to your analog signals. Finally, apply power and verify the active LED illuminates.
