R7C series is CC-Link few point input output module. It can be used as a module with mixed analog input and output and contact input and output by connecting the basic module and the extension module. It can also be used as a 32-point contact input module, 32-point contact output module, and a module with 16 points of contact input and output.
This specification sheet describes the M‑System R7C series remote I/O modules, including basic modules (e.g., DA16, DC16A, DC16B) and add‑on modules (e.g., EA8, EC8A, EC16B). It explains how the modules can be combined to provide mixed analog and discrete I/O, the selection codes for ordering, and the required configuration via DIP switches or the R7CON configuration software.
The document also provides technical data such as supply voltage, insulation resistance, operating temperature, power consumption per module, communication baud rates, and certification details (UL/C‑UL, CE). Wiring diagrams, terminal specifications, and mechanical dimensions are included for proper installation on DIN rails. This manual is written in Chinese.
| Supply Voltage | 24V DC ±10% |
|---|---|
| Insulation Resistance | ≥100MΩ / 500V DC |
| Operating Temperature Range | -10 °C to +55 °C |
| Power Consumption (R7C‑DC16A) | ≈75 mA |
| Communication Baud Rates | 156 kbps, 625 kbps, 2.5 Mbps, 5 Mbps, 10 Mbps |
| Certification | UL/C‑UL non‑incendive Class I, Division 2, Groups A‑D; CE |
The R7C modules operate from a 24 V DC supply with a tolerance of ±10 %.
No, the DC16A (and similar) output modules cannot be connected to add‑on modules such as EA8 or EA16.
Each point can handle up to 0.25 A, with a total of 2.0 A per common terminal.
