8200-1312 is 505XT controller, There are still significant differences compared to the 505D series controllers.

In terms of core hardware, the 8200-1312 operates on an 18–32 VDC low-voltage power supply and holds ATEX Zone 2 explosion-proof certification. It features native onboard I/O, eliminating the need for expansion modules, and displays all signal acquisition and I/O data on an 8.4-inch TFT color touchscreen that supports multiple languages ​​(including Chinese). Specific I/O resources are as follows:

Speed ​​inputs: 2 redundant channels for magnetic reluctance/eddy current probes (0.5–32,000 Hz)

Analog inputs (AI): 8 channels, 4–20 mA (pressure, temperature, flow)

Digital inputs (DI): 20 channels, dry contacts (start/stop, interlock, remote setpoint)

Actuator outputs: 2 channels, servo valve drive (dual-mode: 4–20 mA / 20–200 mA)

Analog outputs (AO): 6 channels, 4–20 mA (load, remote speed transmission)

Relay outputs (DO): 8 channels (2 high-power 5A channels, 6 2A channels; for alarm/trip functions)

Communication: 4 Ethernet ports (Modbus TCP, OPC UA), RS485 Modbus, CAN bus; supports LINKnet distributed I/O expansion

Environmental: -40°C to +85°C; IP54 front panel protection
