This controller is specifically engineered for original equipment manufacturers and system integrators. Consequently, the Schneider TM258LF42DT4L offers a reliable solution for modern machine control architectures. For this reason, many automation engineers prefer this model for their critical projects.

Technical Specifications

The TM258LF42DT4L offers a comprehensive set of technical features. To begin with, it includes 42 discrete I/O points and 4 analogue inputs. The discrete input voltage is rated at 24 V DC. Analogue inputs support current types (0-20 mA, 4-20 mA) and voltage types (±10 V). The analogue input resolution is 12 bits. Additionally, this controller provides 12 discrete outputs and 4 fast outputs. Meanwhile, the fast inputs and outputs support a maximum cable distance of <30 m. The discrete output voltage is 24 V DC, with a voltage limit of 19.2 to 28.8 V. The logic between each channel and the internal part is isolated to 500 Vrms AC. Furthermore, the rated supply voltage is 24 V DC, with a permissible range of 20.4 to 28.8 V. The inrush current can reach up to 100 kA for 70 seconds on the main power supply. As a result, this controller handles power surges effectively.

The TM258LF42DT4L excels in memory and connectivity. For instance, it features 128 MB of flash memory and 64 MB of internal RAM. The integrated connection types are extensive. First, a serial link via RJ45 connector supports Modbus RTU/ASCII with RS232/RS485. Second, an Ethernet port with RJ45 connector enables Modbus TCP/IP using 10BASE-T/100BASE-TX. Third, two USB ports (Mini-B and Type A) provide 480 Mbit/s transfer rates. Finally, a CANopen port with SUB-D 9 connector supports master mode. Moreover, the CANopen port supports various baud rates and bus lengths. For example, it can operate at 125 kbit/s for up to 500 m. It also supports 1 Mbit/s for a maximum of 4 m. Therefore, this flexibility makes the Schneider TM258LF42DT4L suitable for diverse networking scenarios. Indeed, its connectivity options cover most industrial communication needs.

Mechanical and Environmental Parameters

The TM258LF42DT4L is built to withstand harsh industrial environments. Specifically, its dimensions are 237.5 mm in width, 99 mm in height, and 85 mm in depth. The controller is designed for symmetrical DIN rail mounting, which simplifies installation. Additionally, its environmental specifications include a wide operating temperature range. For instance, it works from 0 to 55 °C without derating during vertical mounting. It can even operate up to 60 °C with appropriate derating. Furthermore, the storage temperature ranges from -25 to 70 °C. Relative humidity can reach 5 to 95 % without condensation. Besides these, the IP20 protection class conforms to IEC 61131-2. Pollution degree 2 complies with IEC 60664. Operating altitude spans 0 to 2000 m, while storage altitude extends to 3000 m. As a result, this controller performs reliably in various factory conditions.

Moreover, the controller demonstrates excellent resistance to mechanical stress. For example, it withstands vibration of 1 gn at 8.4 to 150 Hz on DIN rail. Its shock resistance is rated at 15 gn for 11 ms. Additionally, the TM258LF42DT4L offers robust immunity to electrical disturbances. For instance, it includes electrostatic discharge immunity of 4 kV (contact) and 8 kV (air). It also handles surge immunity of 0.5 kV (common mode) and 1 kV (differential mode). Consequently, this product ensures stable operation even in electrically noisy environments. Therefore, users can trust its performance in demanding applications.

Installation Guide

Installing the Modicon M258 TM258LF42DT4L is a straightforward process. First, ensure the DIN rail is securely mounted. Then, clip the controller onto the rail until it locks into place. Next, connect the power supply to the designated terminals. Specifically, the controller requires a 24 V DC supply. After power is connected, proceed with I/O wiring. The terminal blocks are clearly labeled for easy identification. Meanwhile, ensure all connections are tight and secure. Then, connect the communication cables for your specific network. For instance, use appropriate shielded cables for Ethernet and CANopen connections. Finally, power on the system and check the status LEDs. These indicators provide visual confirmation of the controller's operational state. Furthermore, the TM258LF42DT4L offers configurable filtering times. You can set these to 0 ms, 1.5 ms, 4 ms, or 12 ms for specific inputs. As a result, this flexibility allows you to optimize performance for different applications.
