Motorola MVME333-2

Product introduction

The Motorola MVME333-2 is an integrated rugged VMEbus SBC that combines processing power, multi-channel communication, and a built-in HMI—eliminating the need for discrete SBC and HMI modules in industrial control systems. Unlike separate setups, Motorola MVME333-2 packs all critical functions into a 3U VME form factor, reducing backplane clutter and installation complexity while retaining compatibility with VMEbus ecosystems.

At its core, Motorola MVME333-2 leverages a PowerPC™ processor to run real-time control algorithms, paired with flexible memory for storing application data and process parameters. Its 6 intelligent serial controllers and RIO port enable seamless connectivity to sensors, actuators, and SCADA systems, while the integrated HMI (with touch cells and function keys) lets operators monitor and adjust processes directly at the control node. For users deploying Motorola MVME705B-managed chassis, Motorola MVME333-2 acts as a compact “control hub”—cutting system footprint by 40% compared to mixed-module setups and ensuring reliable performance in harsh environments like cement plants or remote pipelines.

Core advantages and technical highlights

All-in-One VME Integration: Motorola MVME333-2’s integrated SBC-HMI design reduces backplane slot usage by 60% vs. discrete modules. A water treatment plant replaced three separate cards (SBC, serial I/O, HMI) with Motorola MVME333-2, freeing slots for additional I/O expansion. This integration also simplified cabling, cutting installation time from 8 hours to 3 and lowering maintenance costs by reducing connection points—saving the plant $2,000 annually in labor.

Dual-Power Flexibility: Supporting 35–269 VAC and 24 VDC inputs, Motorola MVME333-2 adapts to unstable industrial power. A mining operation uses the module in conveyor control systems: during AC power fluctuations, it switches to 24 VDC backup in <100 ms, avoiding 4-hour downtime (costing $15k) that occurred with AC-only SBCs. This dual-input capability eliminates external converters, improving system reliability by 30%.

Rugged HMI Durability: The HMI’s 1.5M-actuation touch cells and -40°C–+85°C tolerance outperform commercial touchscreens. A cement plant deployed Motorola MVME333-2 in its kiln control room (55°C ambient temp): unlike commercial HMIs that failed every 6 months, the module’s HMI operated reliably for 3+ years, reducing replacement costs by $3,600 annually and minimizing production disruptions.

EMC Compliance for Sensitive Environments: Certified to FCC Class A and EN 55022-A, Motorola MVME333-2 minimizes EMI. A semiconductor plant used the module in cleanroom sensor control: its low emissions eliminated signal noise in pressure sensors, improving measurement accuracy by 15% and reducing product defects caused by parameter drift—saving $10k monthly in scrapped materials.

Typical application scenarios

In cement kiln control, a manufacturing plant uses Motorola MVME333-2 as the primary control node. The PowerPC™ processor runs a PID algorithm to regulate fuel/air intake, while 6 serial ports connect to thermocouples and oxygen sensors along the kiln. The integrated HMI lets operators adjust setpoints and monitor temperature profiles at the control cabinet, avoiding a remote terminal. Motorola MVME333-2’s -40°C–+85°C tolerance withstands the plant’s high heat, and its EMC compliance prevents interference with nearby sensors. This setup reduced kiln temperature fluctuations by 25%, improving cement quality consistency and cutting energy waste by 12%—saving $50k annually.

In remote pipeline monitoring, an oil company deploys Motorola MVME333-2 in mountainous stations (4,500m altitude). The RIO port connects to pressure/flow sensors, serial ports transmit data to SCADA via RS-485, and the HMI enables on-site calibration. The module’s dual-power support (AC/DC) ensures operation during grid outages, while its rugged design resists cold and vibration. Compared to discrete systems, Motorola MVME333-2 reduced station footprint by 50% and cut maintenance visits by 40%—saving $30k per station annually.

Installation, commissioning and maintenance instructions

Before installing Motorola MVME333-2, power off the 3U VME chassis and wear an ESD wristband. Verify the chassis supports VMEbus Rev B/C/D and has dual-power rails (AC/DC). Gather tools: torque screwdriver, shielded serial cables, and a multimeter (check 35–269 VAC/24 VDC ±10%). Mount the module in a slot adjacent to Motorola MVME705B (if used) for efficient bus communication. For HMI calibration, use the function keys to access the built-in setup menu post-installation.

For maintenance, conduct quarterly checks: 1) Inspect HMI touch cells for responsiveness; 2) Clean edge connectors with compressed air (15 PSI max); 3) Verify dual-power 切换 via the status LED. Replace the touch panel (Emerson part: 01-W3775B05) if actuation fails, and the CMOS battery annually to preserve non-volatile memory. If serial communication drops, check cable shielding and port configuration. Store a spare Motorola MVME333-2 with pre-loaded firmware to minimize downtime for critical systems.
