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.
