iNexBot C1103 Industrial Robot Controller
1. Product Introduction
The C1103 is a high-performance embedded robot controller developed by iNexBot Technology for complex industrial scenarios. Within a compact body of 103×97×74.5mm, it integrates an Intel J1900 quad-core processor, a dedicated EtherCAT real-time bus, and an E-BUS modular I/O expansion architecture. A single controller supports up to 64 axes of synchronized motion and can independently control 4 robots while connecting external axes such as floor tracks and positioners.
The controller ships with the iNexBot control system and comes preloaded with a range of mature process packages covering core industrial scenarios such as new-energy manufacturing, automotive components, 3C electronics assembly, and smart logistics.
Positioning in one sentence: the C1103 is the upgrade and replacement for the C1102 — the same X86 computing platform, but with more interfaces, a smaller footprint, stronger expandability, and built-in UPS power-failure protection.
2. Five Core Advantages
2.1 E-BUS Modular I/O Expansion
The C1103's most distinctive hardware feature is its E-BUS bus expansion capability. Through the E-BUS interface, the controller can be seamlessly expanded with iNexBot's AL series I/O modules, covering digital I/O, analog I/O, encoder interfaces, and more. Users can flexibly configure I/O combinations to suit their actual production-line needs without replacing the controller hardware, significantly reducing deployment and inventory costs.
2.2 Built-in UPS · Power-Failure Protection
A built-in supercapacitor module provides ≥5 seconds of backup power at full load. In the event of an abnormal power loss, the system has time to save critical data and execute a safe shutdown sequence, eliminating the risk of data loss and equipment damage. On a sudden power failure, current process parameters, program state, and critical data are saved automatically; once power is restored, operation resumes from the breakpoint, preventing scrapped workpieces and production-line downtime.
2.3 4 Network Ports · Double the Interface Density
3 Gigabit Ethernet ports + 1 dedicated EtherCAT OUT port (independent RJ45 physical interface) — twice the network connectivity of the C1102. Supports isolated multi-subnet deployment without an additional switch. The EtherCAT port is a dedicated hardware port that does not occupy a standard network port; the Intel i210 guarantees real-time performance, and a dual-master configuration is supported.
2.4 46% Smaller Footprint
Dimensions of only 103×97×74.5mm (C1102: 230×120×50mm) — a volume of approximately 0.74L vs. 1.38L — allowing flexible deployment in tight control cabinets. Standard DIN-Rail mounting for easy installation and removal. A palm-sized form factor that is among the most compact in its computing class.
2.5 Configurable Interfaces · Flexible Customization
Memory (DDR3L 2/4/8GB), M.2 storage (64G~1TB), and 4G/5G wireless modules can all be configured on demand. The M.2 expansion slot supports WiFi/3G/4G/5G modules for networking and remote-maintenance requirements.
