The Schneider TM221M16RG is a versatile and compact PLC CPU designed for the Modicon M221 range, offering a reliable solution for automation needs in various industrial settings. This logic controller is engineered to operate with a 24 V DC rated supply voltage, ensuring compatibility with standard industrial power systems.
Equipped with 8 discrete inputs that conform to IEC 61131-2 Type 1 standards, including 4 fast inputs, and 2 analogue inputs with a range of 0 to 10 V, the TM221M16RG is adept at handling a variety of signal types. The controller also features 8 relay outputs with normally open contacts, capable of switching a wide range of loads with discrete output voltages of 5 to 125 V DC and 5 to 250 V AC, and a discrete output current of up to 2 A.
The TM221M16RG boasts a discrete I/O number of 16 and allows for the connection of up to 7 I/O expansion modules, providing flexibility for system expansion. The unit's power consumption is efficient, with a maximum of 22.5 W at 24 V when all I/O expansion modules are connected, and as low as 3.6 W without them.
This logic controller features sink or source discrete input logic, a 10-bit analogue input resolution, and a fast conversion time of 1 ms per channel plus one controller cycle time for analogue inputs. It also offers configurable filtering times for inputs, ensuring adaptability to different signal processing requirements.
The TM221M16RG is designed with robustness in mind, featuring a mechanical durability of over 20 million cycles for relay output and an electrical durability that ensures reliable operation even under inductive or resistive loads. The controller includes a built-in real-time clock, adjustable PID regulator for up to 14 simultaneous loops, and high-speed counting inputs.
For programming and communication, the unit is equipped with a mini B USB 2.0 port, non-isolated serial links with RS485 and RS232/RS485 interfaces, and supports Modbus protocol as master or slave. The controller's compact dimensions and CE marking make it suitable for installation on standard DIN rails or panels, ensuring ease of integration into existing systems.
The Schneider TM221M16RG is a smart choice for those seeking a reliable and expandable logic controller for their automation systems, offering a balance of performance, durability, and flexibility.
