Inovance AC810-0122-U0R0 PLC Controller
The Inovance AC810-0122-U0R0 is a compact programmable logic controller from the AC800 series. It features 22 built-in I/O points (12 digital inputs, 10 transistor outputs) and integrates Ethernet and CANopen communication ports. The controller is designed for small to medium-sized automation tasks such as packaging machines, textile machinery, and auxiliary equipment.
CPU Specifications
The AC810 uses a 32-bit ARM Cortex-M3 processor at 120 MHz. Program memory: 128 KB (flash), data memory: 64 KB (RAM). Typical instruction execution time: 0.05 µs for basic logic. The real-time clock (RTC) is battery backed (CR2032). The controller retains retentive memory (8 KB) without battery using EEPROM.
Onboard I/O
12 digital inputs: 24V DC (sink/source), 4 are high-speed (50 kHz) for counters or encoders.
10 digital outputs: NPN transistor, 0.5A per point, 24V DC; two outputs support 100 kHz pulse train for stepper/servo control.
I/O response time: 1 ms typical. The unit also has two analog input channels (0–10V, 12-bit resolution) for sensors like potentiometers or pressure transducers.
Communication Ports
1 x Ethernet (10/100) supporting Modbus TCP, PROFINET, and EtherNet/IP.
1 x CANopen (DB9) master (up to 32 nodes).
1 x RS-485 (terminal block) for Modbus RTU (master/slave).
1 x USB device (mini-B) for programming.
Expansion Capabilities
The AC810 can connect up to 8 expansion modules (Inovance AM series) via the side expansion bus, adding up to 128 digital I/O or 32 analog I/O. Modules include digital I/O, analog I/O, thermocouple, and RTD inputs. Expansion modules are automatically recognized.
Power Supply
Supply voltage: 24V DC (19.2–28.8V). Power consumption: 6 W typical (excluding sensor supply). The unit provides an isolated 24V DC output (200 mA) for powering external devices. Reverse polarity and overvoltage protection are built in. The supply uses a 2.5A slow-blow fuse.
Environmental and Mechanical
Dimensions: 90 mm width x 70 mm height x 60 mm depth. Weight: 0.3 kg. Mounting: DIN rail (EN 60715) or screw mount. Operating temperature: -10°C to 55°C; storage: -20°C to 70°C. Humidity: 10% to 90% non-condensing. Protection class: IP20. Vibration: 2 g (10–55 Hz). The housing is polycarbonate UL94 V-0.
Programming Software
Inovance AutoShop (based on Codesys V3) is used for programming. Supported IEC languages: LD, FBD, ST, SFC, IL. The software supports online monitoring, debugging, and task configuration (cyclic, interrupt, freewheeling). The controller also has a built-in web server for remote diagnostics.
Motion Control Functions
The high-speed outputs can control two axes of stepper or servo drives using pulse/direction signals. The CANopen port connects to Inovance ISH series drives. The controller supports electronic camming and gearing (via software library).
Diagnostics and LEDs
LEDs: PWR (green), RUN (green), ERR (red), I/O status (yellow per channel). The CPU logs up to 50 faults (time stamped). A removable microSD card (up to 8 GB) can store data logs and user programs.
Ordering and Certification
Order code: AC810-0122-U0R0. The unit comes with terminal blocks (spring clamp) and a programming cable. Manual: AC800 Series Hardware Manual (Inovance doc. A030307). CE, RoHS, and UL 508 certified.
