Its design focuses on delivering reliable automation for diverse applications. Users benefit from its simple integration and efficient performance.
h3 Power and I/O Configuration
The TM221ME16R operates on a 24 V DC supply with a voltage range of 20.4 to 28.8 V. It offers 8 discrete inputs that comply with IEC 61131-2 Type 1. Furthermore, the controller includes 2 analog inputs with a 0...10 V range and a 10-bit resolution. For output, it provides 8 normally open relay outputs. These relays can switch 5...125 V DC and 5...250 V AC. Moreover, each relay output handles a current of 2 A.
h3 Communication and Connectivity
This controller supports integrated Ethernet, enabling easy network integration. It includes a USB port (Mini B) for programming. Additionally, a non-isolated serial link (RJ45) supports RS232/RS485 communication. The serial link runs the Modbus protocol, which facilitates master/slave configurations. Therefore, the TM221ME16R acts as a versatile communication hub. Its Ethernet port supports Modbus TCP and Ethernet/IP protocols.
h3 Performance and Memory Specifications
This controller executes 1 KInstruction in just 0.3 ms for periodic tasks. It features a 256 kB RAM for the user application. Moreover, it has 256 kB of internal variables RAM. A built-in flash memory backs up application and data. For long-term data storage, the unit supports an optional 2 GB SD card. The real-time clock ensures accurate time stamping.
h3 Expansion Capabilities
The TM221ME16R allows for system scalability. It supports up to 7 I/O expansion modules. This flexibility helps in adapting the system to complex needs. The power supply can deliver 0.52 A at 5 V and 0.46 A at 24 V for the expansion bus. Consequently, you can easily extend the I/O count without changing the main controller.
h3 Physical Characteristics
The controller has a compact design with dimensions of 90 mm (H) x 70 mm (W) x 70 mm (D). This small footprint saves valuable space in control cabinets. Its weight is only 0.264 kg, which makes installation simple. The unit also features LED indicators for clear status monitoring. These include PWR, RUN, ERR, and I/O state LEDs.
h3 Environmental Resilience
The TM221ME16R performs reliably in various operating conditions. It withstands an ambient temperature range of -10 to 55 °C for horizontal installation. For vertical mounting, the range is -10 to 35 °C. Additionally, it operates in humidity levels from 10 to 95% (non-condensing). The device also offers an IP20 protection degree. It has strong resistance to electromagnetic interference and surges.
h3 Mounting Options
You can mount the TM221ME16R using several methods. First, use a top hat rail (TH35-15 or TH35-7.5) as per IEC 60715. Second, you can mount it directly on a panel or plate. Ensure you maintain adequate clearance for airflow and cabling. Follow the standard safety guidelines during installation. Always disconnect power before starting the mounting process.
h3 Wiring Instructions
Proper wiring is essential for reliable operation. Connect the 24 V DC supply to the 3-terminal power connector. Use shielded cables for analog and fast inputs to minimize noise. For digital inputs, unshielded cable up to 30 meters is acceptable. Similarly, outputs can use unshielded cable up to 30 meters. Verify all connections before powering up the controller.
