Your system has more sensors and actuators than a compact PLC with 24 channels can handle? The Kinco K608-40 comes with 24 digital inputs and 16 outputs, plus two BD slots for CAN, additional interfaces or I/O. Many machines manage without a single expansion module. 🏭 Typical applications Multi-station machines: assembly, test and packaging lines with many limit switches, light barriers and valves. Drives via CANopen: with the KB6-CAN board you control up to 64 CANopen nodes, or Kinco servo and stepper drives via the Kinco motion protocol. Positioning: the transistor variants output pulse and direction on four channels, three of them up to 200 kHz. Building services: pumps, ventilation and inverters via Modbus RTU, visualisation via Modbus TCP. ⚙️ Four variants K608-40DT: 24 V DC supply, 16 PNP transistor outputs K608-40AT: 100 – 240 V AC supply, 16 PNP transistor outputs K608-40DR: 24 V DC supply, 16 relay outputs K608-40AR: 100 – 240 V AC supply, 16 relay outputs 💡 The relay variants have no pulse outputs. For positioning tasks, choose DT or AT. ⚡ Inputs and outputs 24 digital inputs 24 V DC, wired as PNP or NPN, optically isolated, input delay below 40 µs (high-speed channels below 5 µs). PNP transistor outputs: 500 mA per channel at 24 V DC, protected against short circuit, inductive loads and reverse polarity. Relay outputs: 2 A per contact at 30 V DC or 250 V AC, max. 8 A per group of 4 channels, electrical life 100 000 operations at rated load. High-speed counters: 4 channels, HSC0 and HSC1 up to 200 kHz, HSC2 and HSC3 up to 20 kHz single-phase or 10 kHz A/B. 4 edge interrupts on I0.0 to I0.3. Pulse outputs (transistor variants only): 4 channels for PTO (pulse/direction) and PWM, PTO0 to PTO2 up to 200 kHz, PTO3 up to 10 kHz. Positioning instructions and a follow function are included in KincoBuilder. 🔌 Communication Ethernet 10/100 Mbit/s: Modbus TCP client and server, free communication via TCP and UDP, program upload/download and firmware update over the network. 2 × RS-485, galvanically isolated: 1200 to 115 200 bit/s, Modbus RTU master or slave, free protocol and programming on both ports. Up to 32 devices per port. 🧩 Expansion Two BD slots take expansion boards directly on the CPU. BD0 accepts communication and I/O boards (KB6-CAN, KB6-2COM, KB6-4DI, KB6-4DO), BD1 accepts I/O boards only (KB6-4DI, KB6-4DO). On top, up to 14 expansion modules connect to the local bus. The CPU supplies them with up to 1500 mA at 5 V and 360 mA at 24 V. From about 7 modules, or when the current budget runs out, you add the K680 power supply to the module row. 💻 Programming and memory You program the controller with KincoBuilder (IEC 61131-3) in ladder diagram (LD) or instruction list (IL), version V8.5.0.3 or later. The CPU offers 8k instructions of program memory and 20 kB of data memory (16 kB V area, 4 kB M area). 1000 standard instructions execute in 0.3 ms. On top come 256 timers, 256 counters, arrays with up to 1024 elements and a battery-backed real-time clock (deviation below 5 min per month at 25 °C). The V area and counter values are retained on power loss, and the battery is replaceable. 🔗 Compatible with Kinco K5 Terminal layout and power connection match the K5 series, existing K5 programs run without changes, and K5 expansion modules plug in directly. This lets you replace a K5 in the cabinet without rewiring or reprogramming. 🏷️ Manufacturer and standards Kinco Automation, based in Shanghai and Shenzhen, develops controllers, HMIs and drive technology for international machine builders. The K608-40 is CE marked (EN IEC 61000-6-2:2019, EN IEC 61000-6-4:2019) and tested to GB/T 15969.3-2007, which is equivalent to IEC 61131-2:2007. Protection class IP20, operation from −10 °C to +55 °C, 10 % – 95 % relative humidity without condensation, altitude up to 2000 m. 🔧 Mounting On 35 mm DIN rail or with M4 screws on the mounting plate. Dimensions 186 mm × 114 mm × 76 mm, the terminal blocks are pluggable.
