The ioLogik E2262 from Moxa is an intelligent universal I/O controller specifically designed for precise temperature monitoring and industrial automation applications. The device features 8 thermocouple inputs and 4 digital outputs, and enables event-based automation via its Click&Go logic control without requiring an additional PLC, thereby reducing system complexity and costs. The integrated control logic allows programming through a graphical user interface, enabling even users without extensive programming knowledge to utilize its functions.

Applications

The ioLogik E2262 is designed for industrial applications, particularly in areas requiring accurate temperature measurement and control, such as manufacturing, power generation, or process automation. Support for multiple thermocouple types (J, K, T, E, R, S, B, N) makes the device flexible and adaptable regardless of the sensor type used. High measurement accuracy and robust construction enable use in demanding environments with high mechanical and thermal stresses.

Functions and Features in Detail

The 8 thermocouple inputs offer a resolution of 16 bits and a measurement accuracy of ±0.1 % FSR at 25 °C, and ±0.3 % FSR within the operating temperature range of -10 to 60 °C. The TC accuracy is ±5 °C for types J, T, E, S, B and ±8 °C for K, R, N. The Cold Junction Compensation (CJC) has an accuracy of ±0.5 °C at 25 °C and ±1.5 °C in the range of -40 to 75 °C. The sampling rate is 12 samples per second overall, equating to an average of 1.5 samples per channel. The input resistances are rated at ≥1 MΩ, ensuring high impedance and minimal loading effect. The digital outputs are sink-type, with 200 mA per channel and a pulse frequency of 1 kHz. They are equipped with protection functions against overcurrent (0.65 A), overvoltage (45 VDC), and overtemperature (175 °C).

Technology Explained Simply

The Click&Go logic control is based on a graphical programming language that allows logical sequences to be created by connecting function blocks without writing code. This reduces development time and error susceptibility. The integrated Ethernet interface (10/100BaseT(X)) with RJ45 connector and 1.5 kV isolation enables a secure network connection. Support for Modbus TCP/RTU and SNMPv1/v2c/v3 ensures integration into existing networks and monitoring via standard protocols. SNMPv3 security provides authentication and HMAC methods to enhance network security. The serial interface RS-485 (2-wire) with terminal block and baud rates from 1200 to 115200 bps enables communication with legacy systems or other devices in Modbus RTU master mode.

Compatibility and Accessories

The ioLogik E2262 is designed for use with thermocouples of types J, K, T, E, R, S, B, and N. Configuration is performed via a web console or the ioAdmin software, allowing settings to be adjusted remotely. The devices are intended for mounting on a DIN rail or on a wall. Wiring is done with cables in the 16–26 AWG range for I/O and power supply.

Mounting and Installation

The device is delivered in a plastic housing that is compact (115 × 79 × 45.6 mm) and lightweight (250 g). Mounting is either on a DIN rail or on a wall, with wiring using cables in the cross-section range of 16–26 AWG. The operating voltage ranges from 12 to 36 VDC, with a current consumption of 160 mA at 24 VDC. The operating temperature range is -10 to 60 °C, and the storage temperature range is -40 to 85 °C. Relative humidity may be 5–95 % (non-condensing), and the maximum operating altitude is 2000 m.

Operational Advantages

The ioLogik E2262 offers high reliability with an MTBF of 341,063 hours (according to Telcordia SR332). Integrated protection functions against overcurrent, overvoltage, and overtemperature increase operational safety. Certifications according to UL 508, EN 61000-6-2/-6-4, CISPR 32, RoHS, CRoHS, WEEE, and IEC 60068-2-6/-27/-32 for shock and vibration guarantee suitability for industrial applications. The 5-year warranty underscores the quality and durability of the device.
