Moxa ioLogik E1512-M12-CT-T -40 to 85 °C content_copy

The Moxa ioLogik E1512-M12-CT-T is an industrial Ethernet remote I/O module, specifically designed for use in railway applications such as rolling stock. The module features a robust aluminium housing and a vibration-resistant design, engineered to withstand the high mechanical stresses encountered in rail vehicle operations. The extended operating temperature range of -40 to 85 °C ensures reliable performance even under extreme environmental conditions, as encountered in the railway industry.

Applications
This module is primarily designed for data acquisition and control in railway vehicles. It is suitable for monitoring status signals such as door positions, light switches, or operating states of drives, as well as for capturing events like door openings or alarms. Compliance with railway standards EN 50121-3-2, EN 50121-4, and parts of EN 50155 makes it suitable for use in railway infrastructure.

Functions and Features in Detail
The module features 12 digital inputs, which can be configured either as simple digital inputs (DI) or as event counters. The inputs support Dry Contact (ON = short to GND, OFF = open) as well as Wet Contact (NPN or PNP) with a voltage range of 10 to 30 VDC for ON and 0 to 3 VDC for OFF. The inputs are connected via spring-cage Euroblock terminals, enabling secure and quick wiring. The maximum counting frequency is 250 Hz, and the digital filter time is software-configurable to minimize interference. Channel-based isolation with 3 kV DC or 2 kV RMS prevents electrical interference between channels, enhancing operational safety.

Technology Explained Simply
The network interface consists of a 10/100BaseT(X) Ethernet port with an M12 D-coded, 4-pin female connector, designed for use in industrial environments with high mechanical stress. The integrated magnetic isolation of 1.5 kV protects the module from voltage surges in the network. Supported protocols include Modbus TCP Server, Moxa AOPC (Active Tag), and MXIO Library, enabling flexible integration into existing control systems. Configuration is performed via a web console (HTTP) or the Windows-based ioSearch software. The module supports management functions such as BOOTP, DHCP Client, HTTP, IPv4, TCP/IP, and UDP.

Compatibility and Accessories
The module is optimized for integration into railway infrastructure and complies with relevant standards for railway applications. It can be combined with other ioLogik modules and Moxa systems to build decentralized I/O networks. The use of M12 connectors ensures high mechanical stability and reliability in moving vehicles.

Mounting and Installation
Mounting is done either on a DIN rail or optionally on a wall. Wiring is performed via spring-cage Euroblock terminals with a wire cross-section of 16 to 26 AWG for power and I/O lines. Power supply is via a spring-cage Euroblock connection with an input voltage of 12 to 48 VDC. At an operating voltage of 24 VDC, the power consumption is 150 mA.

Operational Advantages
The high mechanical robustness, extended temperature range, and compliance with railway standards make the module particularly suitable for use in rail vehicles. Channel-based isolation enhances operational safety, and flexible configuration via web browser or ioSearch software enables quick commissioning. The integrated LED indicators (PWR, RDY, EXP, LAN, DI-Channels) facilitate diagnosis and status monitoring. The MTBF is 507,064 hours according to Telcordia SR332, indicating high reliability.

Certifications and Environmental Conditions
The module complies with railway standards EN 50121-3-2, EN 50121-4, and parts of EN 50155. It is also certified according to EN 61000-6-2/-6-4, CISPR 32, FCC Part 15B Class A for EMC/EMI, IEC 61000-4-2/-3/-4/-5/-6/-8 for EMS, UL 508 for safety, as well as IEC 60068-2-27 and IEC 60068-2-6 for shock and vibration. Humidity is 5–95 % (non-condensing), and the maximum operating altitude is 2000 m. Storage temperature matches the operating temperature range of -40 to 85 °C. Sustainability certifications include RoHS, CRoHS, and WEEE.

Scope of Delivery
The module is delivered with a 16-pin terminal block (3.81 mm), a 3-pin terminal block (3.81 mm), a quick start guide, and a warranty card. The warranty period is 5 years.
