Product Overview
The TEWS TPMC815-50 is a versatile PMC (PCI Mezzanine Card) industrial I/O module engineered by TEWS Technologies—a leading provider of rugged embedded computing solutions—designed to expand the I/O capabilities of embedded systems in demanding environments such as aerospace, defense, and industrial automation. As a compact, mezzanine-level module, it integrates multiple I/O functions into a single form factor, enabling embedded controllers to interface with a wide range of field devices (sensors, actuators, communication networks) while saving valuable space in constrained systems (e.g., rack-mounted servers, embedded control units). Core features of the TEWS TPMC815-50 include 16-channel digital I/O (configurable as inputs or outputs), 4-channel analog inputs (12-bit resolution), 2-channel analog outputs (12-bit resolution), and support for the PMC bus (PCI Mezzanine Card Standard IEEE 1386.1). With its rugged design (resistant to shock, vibration, and extreme temperatures) and compliance with industrial standards (e.g., EN 61000-6-2 for noise immunity), the TEWS TPMC815-50 ensures reliable operation in harsh conditions—from military ground vehicles to offshore oil rig control systems. Additionally, the TEWS TPMC815-50 supports operating systems like Linux and Windows Embedded, and includes device drivers for easy integration into embedded software stacks, making it ideal for both new embedded designs and retrofits of legacy systems.

Key Features and Benefits
Multi-Functional I/O Integration & Space Optimization
The
TEWS TPMC815-50 eliminates the need for multiple single-function modules by integrating digital I/O, analog inputs, and analog outputs into a single PMC form factor—reducing the number of mezzanine cards required in embedded systems by up to 70%. This is critical for space-constrained applications like military unmanned aerial vehicles (UAVs) or industrial embedded controllers, where every millimeter of space impacts system design. For example, in a factory automation embedded controller, the module can simultaneously read analog temperature sensor data (via 4-channel analog inputs), control digital solenoid valves (via 16-channel digital outputs), and adjust analog motor speed (via 2-channel analog outputs)—all without additional hardware. The configurable digital I/O further enhances flexibility: users can switch channels between input and output modes via software (no hardware reconfiguration needed), adapting to changing application requirements (e.g., reallocating a digital output to an input for added sensor monitoring).
Rugged Design for Harsh Environments
Built to meet the stringent demands of aerospace, defense, and industrial applications, the TEWS TPMC815-50 undergoes rigorous testing to MIL-STD-883H standards—ensuring it withstands extreme shock (100G) and vibration (20G) encountered in military ground vehicles or aerospace launch systems. Its extended temperature variant (-40°C to +85°C) operates reliably in Arctic cold or desert heat, making it suitable for outdoor industrial equipment (e.g., oil wellhead monitoring) or aerospace avionics. The module’s ESD protection (±15kV air) and over-current protection prevent damage from electrostatic discharge (common in dry factory environments) or accidental short circuits (e.g., faulty sensor wiring), extending its lifespan to over 10 years in typical industrial use. For aerospace/defense applications, compliance with MIL-STD-883H also ensures compatibility with high-reliability systems where component failure could have critical consequences.
Seamless Embedded Integration & Software Support
The TEWS TPMC815-50 is designed for easy integration into embedded systems via the PMC bus (IEEE 1386.1), a widely adopted standard for mezzanine cards—ensuring compatibility with PMC carrier boards from leading manufacturers (e.g., Curtiss-Wright, Kontron). It supports popular embedded operating systems (Linux, Windows Embedded, VxWorks), and TEWS provides comprehensive device drivers and software APIs (Application Programming Interfaces) that simplify I/O control and diagnostic programming. For example, a Linux-based industrial controller can use TEWS’s Linux kernel driver to read analog input data in real time or configure digital I/O channels—without writing low-level hardware code. The module’s power-on self-test (POST) and fault logging features further streamline maintenance: technicians can access real-time I/O status and fault history via software, quickly identifying issues like a failed analog sensor (no input signal) or over-current on a digital output—reducing troubleshooting time by up to 50%.
