Moxa ioLogik E1242-T 2-port Switch -40 to 75 °C content_copy

The Moxa ioLogik E1242-T is a member of the ioLogik E1200 Series, an intelligent Ethernet remote I/O solution specifically developed for industrial applications in harsh environments. The device features an integrated 2-port Ethernet switch, enabling a simple Daisy-Chain topology, which allows multiple modules to be directly connected. The ioLogik E1242-T targets OT and IT engineers and supports six common communication protocols: Modbus TCP, EtherNet/IP, RESTful API, SNMP v1/v2c, MXIO, and Moxa AOPC. This protocol versatility ensures seamless data integration into SCADA, IT, and IIoT applications. Configuration is performed via a web browser, the ioSearch tool, or the MCC tool, simplifying setup and maintenance.

Applications
The ioLogik E1242-T is designed for use in industrial environments, particularly in plants exposed to high mechanical and thermal stresses. The T-model variant offers an extended operating temperature range of -40 °C to 75 °C, making it suitable for applications in extreme climatic conditions. Certifications for ATEX Zone 2 and Class I Div. 2 (except for models E1213/E1213-T) allow use in potentially explosive areas. The devices are therefore suitable for use in process industries, power generation, material handling, and automation technology.

Functions and Features in Detail
The device features configurable digital inputs and outputs, supporting up to 16 digital inputs (250 Hz, wet/dry contact) and up to 16 digital outputs (max. 500 mA, pulse up to 500 Hz). Additionally, up to 6 relay outputs (5 A @ 250 VAC/30 VDC) are available. Analog inputs include 4 to 8 channels with 16-bit resolution (0–10 VDC, 0/4–20 mA), while analog outputs offer 4 channels with 12-bit resolution (0–10 VDC, 0/4–20 mA). For temperature measurement, 6 channels are provided for RTDs (PT50–PT1000) and 8 channels for thermocouples (Type J/K/T/E/R/S/B/N). Peer-to-peer communication enables direct connection of inputs and outputs across different modules without requiring a central controller. The push technology via the MX-AOPC UA server reduces data volume, as status changes are actively reported instead of the server constantly polling.

Technology Explained Simply
The integrated Ethernet technology with 10/100BaseT[X] enables stable and fast data transmission. The Daisy-Chain topology reduces the number of required cables and simplifies network configuration. Power supply is via an input range of 12 to 36 VDC, with power consumption between 110 and 200 mA at 24 VDC. The plastic housing is compact (27.8 × 124 × 84 mm) and lightweight (200 g), making it easy to install. Mounting is either on a DIN rail or on the wall. Protection ratings according to IEC 60068 include ESD, EFT, Surge, Vibration, Shock, and Drop, highlighting the device’s robustness in industrial environments. Certifications CE, FCC, RoHS, and UL 508 guarantee compliance with international safety and environmental standards.

Compatibility and Accessories
The ioLogik E1242-T is compatible with various models of the ioLogik E1200 Series, enabling flexible expansion of the I/O structure. Support for Modbus TCP and EtherNet/IP allows integration into existing automation systems. Customizable Modbus TCP addressing simplifies adaptation to specific requirements. The device can be connected to other modules in the series using a Daisy-Chain topology, enabling decentralized control. Configuration via web browser, ioSearch, and MCC tool allows centralized management of multiple devices.

Mounting and Installation
Mounting is either on a DIN rail or on the wall, with the compact and lightweight housing simplifying installation. Integrated terminal blocks (8-pin, 12-pin, 3-pin) facilitate wiring. The included quick start guide supports setup. Power supply is via 12–36 VDC, enabling connection to common industrial power supplies.

Operational Advantages
The ioLogik E1242-T offers high operational reliability due to its robust construction and certifications for explosive environments. The push technology reduces network load and improves response time for status changes. Support for multiple protocols enables flexible integration into existing systems. The long MTBF (up to 923,027 hours, model-dependent) and the 5-year warranty (except E1214: 2 years) underscore the device’s reliability. Decentralized control via peer-to-peer communication reduces dependency on central controllers and increases system flexibility.

Scope of Delivery
The scope of delivery includes 1x ioLogik E1200 Series Remote I/O, 1x 8-pin terminal block (3.81 mm), 1x 12-pin terminal block (3.81 mm), 1x 3-pin terminal block (5.00 mm), 1x quick start guide, and 1x warranty card.
