More Information

Overview Manuals Specifications Application Operating Environment Monitoring and Control

Features:

  • 8 analog output channels for 0-20 mA or 4-20 mA with 15-bit resolution
  • ≤4 ms conversion time, ±0.1% accuracy, and 1400 V DC isolation
  • Open/short circuit detection, configurable fallback modes, IP20 protection
The BMXAMO0802 provides essential signal output functions critical to the entire control path, serving as the primary interface between the control system and field actuators, directly affecting the proper, normal operation of the overall automation system. One BMXAMO0802 module can handle up to eight analog output channels, with each channel independently configurable for the required current range.

For applications requiring precise control across temperature variations, the BMXAMO0802 delivers exceptional accuracy with 0.1% of full scale at 25°C reference temperature and ≤0.25% across the full 0-60°C operating range. The module features temperature drift of only 45 ppm/°C for both output ranges, ensuring stable performance in varying environmental conditions.

The BMXAMO0802's robust diagnostic and protection features ensure reliable operation in demanding industrial environments. The module provides 1400 V DC isolation between channels and ground, as well as between channels and the bus. Comprehensive fault detection on the BMXAMO0802 includes open circuit detection for 4-20 mA outputs and short circuit detection for 0-20 mA outputs, with configurable fallback modes for safe operation during communication loss.

The BMXAMO0802 Schneider Analog output module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Water and Wastewater Management: Controls proportional dosing pumps, chlorine injection systems, and regulates the positioning of automated main water valves.
  • HVAC and Building Automation: Regulates large fan speeds in air handling units (AHUs) via Variable Frequency Drives (VFDs) and modulates chilled/hot water valves for temperature control.
  • Chemical & Petrochemical Processing: Manages continuous flow rates by driving electronic control valves and regulates heating elements via SCR power controllers.
  • Standard Version (BMXAMO0802): Operates efficiently from 0°C to +60°C (32°F to 140°F).
  • Ruggedized Version (BMXAMO0802H): Extends the thermal range from -25°C to +70°C (-13°F to 158°F) for extreme outdoor enclosures or desert/arctic deployments.
  • Humidity Limits: Operates within 10% to 95% relative humidity (RH), non-condensing.
  • Isolation Specs: It is a non-isolated module between channels. This means all 8 channels share a common internal ground. Users must ensure that field devices are either properly isolated externally or share the same ground potential to prevent ground loops from skewing the signal.
  • Digital-to-Analog Scaling: The module features built-in internal conversion. Engineers can configure scaling directly in the software (e.g., mapping a raw PLC internal variable of 0 to 10000 or -32768 to 32767 directly to a physical 4–20 mA signal).
  • Output Ramping: Supports software-configured output ramp limits to prevent sharp, sudden current spikes from hammering mechanical valves or tripping motor drives.
  • Open-Circuit Detection (Wire-Break): When configured in the 4–20 mA operating range, the module actively monitors loop resistance. If a field wire snaps or a terminal loosens, the module detects a drop below 4 mA, triggers an Open Loop Error, logs a system bit in the PLC register, and illuminates the ERR LED.
Description
The Model BMXAMO0802 is a precision analog output module designed for the Modicon M340 automation platform, offering eight independent output channels for current signals. Each channel of the BMXAMO0802 supports field-configurable 0-20 mA or 4-20 mA output ranges, providing flexibility for driving various industrial actuators, valves, and recording devices.

Measurement accuracy is a key feature of the BMXAMO0802, with exceptional performance across its operating range. At 25°C reference temperature, the BMXAMO0802 achieves ±0.1% of full scale accuracy, maintaining ≤0.25% of full scale across the full 0-60°C operating temperature range. 

Diagnostic capabilities enhance the reliability of the BMXAMO0802 in critical applications. The module features open circuit detection for 4-20 mA outputs and short circuit detection for 0-20 mA outputs, enabling rapid identification of field wiring issues. Configurable fallback modes on the BMXAMO0802 allow predefined output states to be set for safe operation in the event of communication loss or processor halt.

Electrical isolation and environmental robustness are prominent features of the BMXAMO0802. The module provides 1400 V DC isolation between channels and ground, as well as between channels and the bus, ensuring signal integrity and personnel safety. Load impedance for the BMXAMO0802 is specified at ≤350 Ohm for both current output ranges.
