Product Advantages ​

Compact Size ​

At just 72×140mm, the R2C is significantly smaller than the R4C/R4D (122×200mm) and R5B (116×210.9mm), making it easy to install inside space-constrained control cabinets or equipment while saving installation space.

Expandable ​

The R2C supports cascading expansion via the EtherCAT bus, allowing more IO nodes to be added as needed to flexibly expand system scale.

Built-In DIN Rail Slot ​

The R2C has a built-in standard DIN rail mounting slot, so it can be clipped directly onto a DIN rail for quick, easy installation and removal — ideal for rapid layout of standard control cabinets.

Reliable Quality ​

The R2C uses an industrial-grade design, supports 24V DC power, an operating temperature range of 0~60°C, and withstands 95% relative humidity (non-condensing), adapting to complex industrial environments. With a 100Mbps bus rate and a minimum communication cycle of 200us, it ensures high-speed, stable data transmission.

Q&A ​

Q: What is the difference between the R2C and the R4C/R4D/R5B?

A: The R2C is a compact IO module with the smallest dimensions (72×140mm). It provides only 16 DI + 16 DO (MOSFET output) and has no analog interfaces or encoder interface, making it suitable for space-constrained scenarios that only need digital input/output. The R4C/R4D are larger (122×200mm) and additionally provide 2 AI + 2 AO + encoder interface + CAN expansion. The R5B is the largest (116×210.9mm) and provides 20 DO (16 transistor + 4 relay) + analog + encoder.

Q: Which EtherCAT functions does the R2C support?

A: The R2C supports a 100Mbps bus rate and distributed clock (DC) functionality, with a minimum communication cycle of 200us. It can connect with INEXBOT controllers and master station devices that support the standard EtherCAT protocol.

Q: Can the R2C be expanded via the bus?

A: Yes. The R2C can be cascaded with other IO modules or master station devices via the EtherCAT bus to expand system scale.

Q: How is the R2C installed?

A: The R2C has a built-in standard DIN rail mounting slot and can be clipped directly onto a DIN rail for quick, easy installation and removal.

Q: What are the characteristics of the R2C's MOSFET output?

A: The R2C uses MOSFETs as the digital output elements, offering fast response, long service life, and no mechanical wear — ideal for high-frequency switching industrial applications.

Q: What is the operating temperature range of the R2C?

A: The R2C operating temperature range is 0~60°C, with an even wider storage temperature range, making it suitable for industrial site deployment.
