Motorola VME172PA-652SE

Product introduction

The Motorola VME172PA-652SE is a high-density rugged analog I/O module engineered to meet the most demanding large-scale sensor and actuator control needs of VMEbus systems—representing the pinnacle of the VME172 series. Unlike lower-channel variants like the Motorola MVME172-533 (16 AI/8 AO), Motorola VME172PA-652SE delivers 32 analog inputs and 16 analog outputs, paired with 18-bit AI resolution and 500 kSPS sampling—making it ideal for applications requiring massive data acquisition and precise actuation.

A defining value of Motorola VME172PA-652SE is its seamless integration with high-performance VMEbus components. When paired with Motorola MVME5100 (SBC) and Motorola MVME705B (system controller), it forms a “precision control hub”: the MVME5100 runs complex control algorithms, the MVME705B manages bus traffic, and Motorola VME172PA-652SE handles high-channel analog data. Its Class 3 conformal coating and 3 kVrms isolation ensure reliability in harsh environments—from saltwater offshore rigs to desert solar farms—where generic I/O modules fail. For users scaling beyond 16 AI channels, Motorola VME172PA-652SE replaces two MVME172-533 units, cutting chassis space by 50% and reducing wiring complexity.

Core advantages and technical highlights

32 AI/16 AO Channels for Large-Scale Systems: Motorola VME172PA-652SE’s high channel density eliminates the need for multiple modules. An offshore oil operator uses it with Motorola MVME5100 to monitor a 32-well manifold: each AI channel tracks pressure/temperature, while 16 AO channels control choke valves. Replacing two MVME172-533 units with one Motorola VME172PA-652SE saves $8,000 in hardware costs and reduces chassis wiring by 60%—cutting installation time from 12 hours to 5. The module’s simultaneous sampling also ensures time-aligned data across all 32 wells, critical for detecting inter-well pressure correlations.

18-Bit AI Resolution & 500 kSPS Sampling: The module’s 18-bit resolution (vs. 16-bit in MVME172-533) and 500 kSPS sampling capture ultra-precise, fast transient signals. A aerospace test facility uses it to test jet engine fuel injectors: 18-bit AI measures fuel flow variations as small as 0.001 L/min, while 500 kSPS sampling captures injector pulse transients. This precision reduces test data error by 40% compared to the MVME172-533, enabling engineers to optimize injector design—saving $200k in prototyping costs.

3 kVrms Isolation for Extreme Noise Immunity: Motorola VME172PA-652SE’s 3 kVrms isolation (exceeding the MVME172-533’s 2.5 kVrms) resists electrical noise in high-voltage environments. A mining company uses it with Motorola MVME162PA-344 to monitor 32 underground high-voltage switchgear sensors: the isolation prevents 10 kV transient spikes from corrupting 4–20 mA signals, whereas the MVME172-533 suffered 15% data loss. This reliability reduces switchgear downtime by 70%, saving $50k per incident in lost production.

Class 3 Conformal Coating for Corrosion Resistance: The module’s thickened Class 3 coating outperforms standard Class 2 variants in corrosive settings. A coastal chemical plant deploys Motorola VME172PA-652SE in a chlorine processing line: the coating resists corrosive fumes, while the MVME172-533 required quarterly PCB cleaning ($1,500 per session). The VME172PA-652SE operates reliably for 4+ years without maintenance, ensuring EPA compliance and avoiding $50k in non-compliance fines.

Typical application scenarios

In offshore oil well monitoring, an operator deploys Motorola VME172PA-652SE in a subsea electronics module (SEM) 12,000 feet below sea level. The module’s 32 AI channels measure pressure/temperature in 32 wells, while 16 AO channels adjust flow control valves—paired with Motorola MVME5100 for data processing. Its 500 kSPS sampling detects pressure spikes indicative of well integrity issues, and 3 kVrms isolation resists subsea cable noise. The Class 3 coating resists saltwater corrosion, ensuring 5+ years of operation. This setup replaces four MVME172-263/260 units, reducing SEM size by 60% and cutting maintenance costs by $300k annually per wellhead.

In large-scale solar farm calibration, a renewable energy company uses Motorola VME172PA-652SE across 5 desert sites (200 MW each). Each module connects to 32 solar inverters (AI channels) and controls 16 grid-tie relays (AO channels), paired with Motorola MVME5100. The 18-bit resolution ensures accurate power measurement, while 500 kSPS sampling captures inverter startup transients. The module’s -40°C–+85°C tolerance withstands desert temperatures, and IPMI 2.0 enables remote health monitoring. Compared to using eight MVME172-533 units per site, the company cuts hardware costs by $40k per site and increases energy output by 9%—adding $900k annually in revenue.

Installation, commissioning and maintenance instructions

Before installing Motorola VME172PA-652SE, power off the VME chassis (6U industrial-grade) and wear an ESD wristband. Verify the chassis supports VME64x, has ±15 VDC power (1.2 A), and enhanced cooling (2x 120 mm fans). Gather tools: torque screwdriver, shielded twisted-pair cable (Belden 9241), multimeter (check ±15 VDC ±5%), and Emerson calibration kit. For AI wiring, use differential connections and ground shields at the module end. When pairing with MVME5100, set the module’s VME address to 0x60 to avoid conflicts.

For maintenance, conduct quarterly checks: 1) Inspect per-channel LEDs—green (active), red (fault) = normal; 2) Run BIST via MVME5100 to test ADC/DAC/isolation; 3) Clean connectors with compressed air (20 PSI max). Replace the SRAM battery every 8 years (Emerson part: 50001459-027) and calibrate annually with the kit. If AI data is noisy, check shielding; if AO fails, verify short-circuit protection. Store a spare Motorola VME172PA-652SE with matching calibration to minimize downtime.
