The Moxa ioLogik E1512-M12-T is an Ethernet remote I/O module, specifically developed for use in rolling stock. It features a robust aluminium housing, channel-to-channel isolation, and a vibration-resistant design, complying with railway-specific standards EN 50121-3-2, EN 50121-4, and key sections of EN 50155. The module is designed for harsh environments characterised by high mechanical stress, extreme temperatures, and electromagnetic interference. Configuration is performed via a web browser or the ioSearch Windows tool, enabling flexible integration into existing systems. Supported protocols include Modbus TCP Server, Moxa AOPC (Active Tag), and MXIO Library, facilitating integration into SCADA or remote monitoring systems.

Applications

The ioLogik E1512-M12-T is primarily intended for use in rolling stock, where high demands on reliability, mechanical stability, and environmental resistance apply. It is also suitable for industrial applications requiring compact, network-capable data acquisition and control. Its high electromagnetic compatibility (EMC) and mechanical robustness make it appropriate for environments with strong vibrations, such as those found in vehicles or production facilities.

Functions and Features in Detail

A central feature of the module is its dual functionality: it provides 4 digital inputs and outputs, which can be configured as DIOs (Digital I/O) via software. This allows flexible use of the channels, with each channel capable of functioning as either an input (DI) or output (DO). The inputs can operate in DI mode or as event counters, achieving a counting frequency of 250 Hz. The outputs can operate as DO or as pulse output, supporting a pulse frequency of 500 Hz. The current capacity of the outputs is 200 mA per channel. Protection features include overvoltage protection (35 VDC), overcurrent protection (0.65 A per channel at 25 °C), and overtemperature shutdown at typically 175 °C.

Technology Explained Simply

The module features an Ethernet port with 10/100BaseT(X) and an M12 D-coded, 4-pin connector, ensuring a secure and vibration-resistant connection. Magnetic isolation of 1.5 kV protects internal circuits from interference. Power supply is via a spring-loaded Euroblock connector in the range of 12 to 48 VDC, with power consumption of 150 mA at 24 VDC. The operating temperature ranges from -40 to 85 °C, enabling use in extreme environments. Humidity of 5–95 % (non-condensing) and maximum altitude of 2000 m highlight its suitability for diverse geographical and climatic conditions.

Compatibility and Accessories

The module is designed for integration into existing networks and supports protocols such as Modbus TCP, MXIO, and MX-AOPC UA Server. Configuration is performed via web console (HTTP) or the ioSearch tool for Windows. The network interface enables communication over IPv4, TCP/IP, and UDP, with BOOTP and DHCP supported for network configuration. LED indicators (PWR, RDY, EXP, LAN, DI, DO) provide visual status indication.

Mounting and Installation

The module can be mounted on a DIN rail or optionally fixed to a wall. Wiring is done via spring-loaded Euroblock terminals with a cable cross-section of 16–26 AWG for I/O and power supply. Installation is simple and requires no special tools.

Operational Advantages

The combination of compact design, high reliability, and flexible configuration makes the ioLogik E1512-M12-T an efficient solution for data acquisition and control in rolling stock. The high MTBF of 554,122 hours (according to Telcordia SR332) underscores its longevity. Certifications according to EN 50121-3-2, EN 50121-4, and EN 50155 (partially), as well as EMC standards such as EN 61000-6-2/-6-4 and CISPR 32, guarantee suitability for use in rail vehicle technology. Safety certification UL 508 and mechanical tests according to IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock) confirm its robustness. Sustainability certifications RoHS, CRoHS, and WEEE demonstrate environmental compatibility.
