Own the control platform, connect field devices, and configure I/O for each application.

Beijing YiLink Technology introduces the yiPLC programmable logic controller series for equipment manufacturing, process control, and industrial IoT. Built around YC200 controller CPUs and YM200 I/O modules, yiPLC supports applications spanning field acquisition, logic control, and equipment connectivity.

An independently developed control platform

yiPLC development covers hardware, the yiOS hardware/software abstraction layer, PLC compilation and runtime, and the engineering toolchain. Equipment makers can adapt applications to their process, communication, and delivery requirements while building on a common platform. Standard industrial interfaces and protocols help integrate the controllers into existing automation systems.

YC200 controller CPUs: acquisition, control, and connectivity

YC200-3A2D2U: 3 × 4–20 mA analog inputs, 2 × ±10 V analog outputs, dual serial ports, dual isolated RS-485, a CAN backplane, and three RJ45 ports with different functions. Designed for current-signal acquisition and analog control.
YC200-3V2D2U: 3 × ±10 V bipolar inputs and 2 × ±10 V outputs for voltage sensors, displacement or load-cell signals, and bipolar closed-loop control.
YC201-3A1D2O2U: 3 × 4–20 mA inputs, one analog output, and two onboard transistor digital outputs for equipment combining analog adjustment with local switching.

Depending on the model, YC200 offers Ethernet, CAN, RS-485, RS-232, TTL, and USB connectivity; Wi-Fi, BLE, or CAT.1 options depend on model and configuration. The three RJ45 ports serve different functions, including debugging, bus-signal breakout, and industrial Ethernet. They are not three interchangeable standard Ethernet ports. Check each model's details for its interfaces and options.

YM200 expansion modules: backplane or remote I/O

In backplane mode, YM200 modules connect to YC200 over the CAN backplane for centralized cabinet expansion. In remote I/O mode, a module can be installed near sensors or actuators and connected over CAN or RS-485 as supported by that model. CAN variants may use CANopen; RS-485 variants may use Modbus RTU. Third-party integration depends on the model, protocol, wiring, and power configuration.

YM200-16I16O: 16 optocoupler-isolated digital inputs and 16 transistor outputs for buttons, limit switches, position feedback, and switching loads.
YM201-16I16OP: 16 digital inputs and 16 sourcing PNP outputs, with 24 V undervoltage detection and short-circuit protection.
YM200-04M: four latching relay contacts with pulse switching and state retention through power loss.
YM200-04PT20: four-channel PT100 acquisition with 3-wire/4-wire support and linearization compensation.
YM200-04PT30: four-channel PT1000 acquisition with digital filtering for industrial multi-point temperature monitoring.

Local operator interface

YHM-86 is a 4-inch capacitive-touch HMI with AI voice interaction, CAN, RS-485, Wi-Fi, and BLE for equipment operation and status display.

Supporting temperature and pressure calibration equipment

For temperature calibration equipment, YC200 can acquire temperature-transmitter signals and support analog adjustment and process interlocks; YM200-04PT20/PT30 add multi-point PT100/PT1000 acquisition. For pressure and biological-sterilizer calibration equipment, YC200's 4–20 mA inputs can connect pressure transmitters, while its analog and digital I/O can help integrate valves, pumps, status monitoring, and automated test sequences.

yiPLC provides a control and data-acquisition foundation that can work alongside the TB-01 pressure data acquisition device, TBX-01 biological sterilizer calibration system, and yiCali calibration software. A PLC does not replace calibration standards, methods, measurement-accuracy assurance, or traceability; system capabilities depend on the selected products and configuration.

Engineering tools and product details

The yiPLC Live Web engineering environment provides PLC programming, project management, and simulation tools for development and iteration. Browse the complete yiPLC product catalog for model specifications, images, and selection information.

I/O combinations, communication interfaces, wireless options, and protocol configurations vary by model. Refer to the corresponding product documentation and delivered configuration when selecting and using equipment.
