General
Air humidity	5–95 % (nicht kondensierend)

The ioLogik E2240 from Moxa is an Ethernet I/O server designed for decentralized data acquisition and control in industrial applications. The device is based on the ioLogik E2200 series and enables processing of input and output signals over a network, with control logic configured locally via the Click&Go™ function. This logic supports up to 24 user-defined rules that can trigger alarms or execute control commands without requiring external PC control. Communication is event-driven via the integrated MX-AOPC UA server, minimizing network traffic as data is transmitted only upon status changes or defined events. The E2240 is thus suitable for applications requiring rapid response to process changes, such as in power supply, environmental monitoring, or telecommunications infrastructure.

Applications

The ioLogik E2240 is suitable for industrial monitoring and control tasks, particularly in environments with high demands for reliability and operational safety. The operating temperature ranges from -10 °C to 60 °C (standard version), with T-models capable of operation down to -40 °C. The robust construction with plastic housing and DIN rail mounting allows flexible installation in enclosures or on walls. The devices are designed for use in harsh environments, with storage temperature up to 85 °C and humidity up to 95 % (non-condensing) permitted.

Functions and Equipment in Detail

The device features 8 analog inputs capable of measuring voltages from ±150 mV to ±10 V and current signals from 0/4–20 mA with a resolution of 16 bits. Two analog outputs support voltages from 0–10 V and current signals from 4–20 mA with 12-bit resolution. The inputs and outputs are designed for precise measurement and control of process variables such as pressure, temperature, or flow rate. Additionally, the E2240 models are equipped with configurable digital I/Os, with the exact number depending on the model. The integrated real-time clock (RTC) with battery backup ensures accurate timestamping of events, even during power failure.

Technology Explained Simply

The ioLogik E2240 communicates via an Ethernet interface (10/100BaseT(X), RJ45) with 1.5 kV isolation, ensuring high immunity to interference. Additionally, an RS-485 interface (2-wire, terminal block) is available for communication with Modbus RTU master devices. Configuration is performed via a web browser, the ioAdmin software (Windows), or through DHCP/BOOTP/HTTP. Support for protocols such as Modbus TCP, SNMP v1/v2c/v3, MXIO, and CGI enables easy integration into existing SCADA and network management systems (NMS). Security is ensured via SNMPv3 with authentication and HMAC encryption.

Compatibility and Accessories

The ioLogik E2240 is compatible with various industrial standards and protocols, including Modbus TCP and RTU, MX-AOPC UA, as well as MXIO libraries for Windows and Linux. The devices can be integrated into existing networks, with push technology optimizing network traffic. Configuration is performed via standardized interfaces, enabling connection to various control and monitoring systems. The devices are designed for industrial environments and comply with certifications UL 508, EN 61000-6-2/-6-4, RoHS, and WEEE.

Mounting and Installation

The ioLogik E2240 can be mounted on a DIN rail or fixed to a wall. Power supply is via a screw terminal with input voltage of 12–36 VDC. Power consumption is 95–202 mA at 24 VDC, with the exact value depending on the model. The connection terminals enable secure and reliable connections for sensors and actuators. LED indicators (PWR, RDY, Serial, I/O Status) support visual diagnosis of operational status.

Operational Advantages

Local control logic via Click&Go™ reduces dependency on central control systems and enables rapid response to events. Event-driven data transmission minimizes network traffic and improves system efficiency. Support for a wide range of protocols and easy configuration via web browser or ioAdmin software facilitates integration into existing systems. The high MTBF (up to 341,063 hours) and certifications according to UL 508 and EN 61000-6-2/-6-4 guarantee high operational safety and reliability in industrial applications. The devices are designed for use in harsh environments, with operating temperature down to -40 °C (T-models).

Scope of Delivery

The scope of delivery includes 1x ioLogik E2200 series Remote I/O, 1x quick start guide, and 1x warranty card. The warranty period is 5 years, with E2214 models having a 2-year warranty. The warranty applies to the device and the documents included in the scope of delivery.

The ioLogik E2240 is thus a powerful, flexible, and reliable solution for decentralized data acquisition and control in industrial applications. The combination of local logic, event-driven communication, and broad protocol support makes the device a valuable component in modern automation systems.
