YC201-3A1D2O2U Modular PLC CPU (3AI/1AO/2DO/2Serial)

Hybrid automation controller with 3x 4-20mA inputs, 1x analog output, 2x local transistor digital outputs (DO), and 2 serial ports, ideally suited for equipment requiring both analog and switching outputs like FLR1000.

Technical Specifications

Power Supply	24V DC Nominal Industrial Supply
I/O Channels	3AI (4-20mA) + 1AO (±10V) + 2DO (Transistor) + 2 Serial
Serial & Ports	COM1 (10.1" HMI touch panel) + COM2 (Debug) + RS485A (pH sensor)
Network & Ethernet	ETH1 (Debug) + ETH2 (Backplane) + ETH3 (Cloud SCADA over MQTT)
Backplane Bus	CAN 2.0A/B Daisy-Chain Backplane
Selection Guide	Optimal for hybrid automation equipment like bioreactors, fermenters (FLR1000), and water treatment units needing both analog PID and local actuators.

Application Scenarios

Engineered to empower diverse industrial, metrology, and intelligent IoT scenarios.

Bioprocess & Fermentation

FLR1000 Fermenter End-to-End Control

Delivers multi-channel thermal PID loop, pH regulation, automated dosing valves, and 10.1-inch bilingual HMI synergy for advanced bioreactors.

Smart Manufacturing

Assembly Lines, Packaging & Tooling Control

Combines YC200 CPU with YM200 16I/16O modules for microsecond sensor reading and solenoid actuation, supporting mixed LD and ST programming.

Distributed Utilities

Unattended Pumping Stations & Water Utilities

Native industrial Ethernet and RS-485 links smart flowmeters and circuit breakers directly to Web SCADA over MQTT with offline resilience.

High Reliability & Zero Power

Latching Relay Bistable & State Retention

Employs YM200-04M latching modules to retain valve and contact states during power failures with zero steady-state power consumption.

Product Advantages

High Precision & StabilityEngineered to stringent metrological and industrial standards with exceptional repeatability and long-term durability.

IoT & Cloud EcosystemNative integration with YiOS IoT platform and WebConsole tools for remote telemetry and automated reporting.

Modular & Easy IntegrationStandardized interfaces and plug-and-play architecture significantly reduce on-site deployment and integration costs.
