PLC Backplane and Communication Characteristics

The TM221CE40R supplies 0.52 A on the 5 V expansion bus and 0.24 A on the 24 V expansion bus for connected expansion hardware. The controller supports up to 7 local I/O expansion modules or 14 remote I/O expansion modules.

Ethernet communication uses an RJ45 10BASE-T/100BASE-TX interface with a specified copper cable distance of 100 m. Supported services include Modbus TCP client and server functions and Ethernet/IP adapter operation. The serial RJ45 interface supports RS232 or RS485 communication at up to 115.2 kbit/s.

The relay output stage is rated for 2 A per output, with a maximum current of 7 A per output common. Relay mechanical durability is specified at 20,000,000 cycles, while switching frequency at maximum load is limited to 20 operations per minute.

Frequently Asked Questions

Q: How many expansion modules can the TM221CE40R support?
A: The controller supports up to 7 modules in a local I/O architecture or 14 modules in a remote I/O architecture.

Q: What communication interfaces are integrated?
A: The controller has a Mini B USB 2.0 port, a non-isolated RJ45 RS232/RS485 serial link, and an RJ45 Ethernet interface.

Q: What are the analog input characteristics?
A: There are 2 analog inputs with a 0 to 10 V range and 10-bit resolution. The specified conversion time is 1 ms per channel plus one controller cycle.

Field Installation Guidelines

• Mount the controller on a TH35-15 or TH35-7.5 DIN rail compliant with IEC 60715, or use the specified plate/panel mounting arrangement.
• Maintain the specified installation orientation when applying the operating temperature limits. Horizontal installation permits -10 to 55 deg C; vertical installation permits -10 to 35 deg C.
• Route analog input wiring separately from relay output and high-current conductors where practical. The specified maximum analog cable length is 1 m for unshielded wiring.
• Use shielded cabling for fast-input circuits where the specified cable limit is 10 m. Digital input and relay output wiring have specified maximum distances of 30 m when unshielded.
• Connect removable terminal blocks with power isolated during installation and maintenance. Verify the supply range before energizing the controller.
• Keep Ethernet and serial communication wiring separated from relay output wiring to reduce conducted coupling.
• Ensure the IP20 protective cover is correctly installed after wiring.
• Observe the specified insulation ratings when connecting field circuits. The source specifies 500 VAC insulation between inputs and internal logic and 2300 VAC between the supply and internal logic.
