DI and DO	The DIO function is programmable and can be defined as input (DI) or output (DO) via parameter settings. DI can only accept passive dry contact input signals. DO is an open-collector output with a load capacity of up to 200mA; an external 24V signal is required to drive intermediate relays.

Core Hardware & Acquisition

24‑bit high‑speed multi‑channel synchronous data acquisition, with full 5‑digit data display covering a reading range of ±10000.

Equipped with a 32‑bit RISC industrial‑grade microprocessor, offering superior noise immunity and fast system response.

Control‑output refresh interval: 50 ms, optimized for fast‑dynamic control processes.

Communication & Multi‑unit Synchronous Control

Dual‑channel Modbus‑RTU as standard; optional Modbus‑TCP Ethernet for extended networking.

Supports communication data synchronization: automatic SV (Set‑Value) sync for multi‑controller parallel operation, realizing coordinated synchronous control of multiple instruments.

Furnace carbon‑potential control via bus‑driven digital PID. Directly controls one or multiple digital power‑regulating devices to build a fully‑digital control system.

Communication data complies with 16‑bit integer standard; auto‑switches to 32‑bit integer read/write when values exceed 16‑bit range, ensuring high‑precision, full‑resolution real‑time process‑control data access.

Algorithm & Calculation Capability

Dual‑channel mathematical computation module for complex algorithm logic.

Integrated high‑precision carbon‑potential measurement and control functions.

Supports non‑standard signal input and multi‑point linearization correction; compatible with 47 types of standard industrial sensor signals.

I/O, Alarm & Digital Interface

4‑channel hard‑contact alarm & program‑controlled outputs.

9‑channel programmable DIO (Digital Input / Output). Each channel is software‑configurable as either digital input or digital output to match field requirements.

Dual‑sensor support: high‑/low‑temperature switching and sensor redundancy switching. Automatically switches to backup measurement channel upon primary‑sensor failure.

Program Profile & PID Group Control

Program curves support arbitrary timed outputs for all 9 DIO channels.

Two output modes integrated: fixed time‑base output and program‑profile time‑base output for flexible configuration.

Two profile editing modes: rate‑based ramp‑curve mode and classic time‑based curve mode.

Full‑screen overview display, providing real‑time visibility of all process‑control parameters.

Storage for 20 recipes, up to 50 segments per recipe; supports intra‑segment cycle and full‑program cycle execution.

10 groups of group‑switchable PID parameters + 10 groups of grouped output‑limit controls, covering diverse industrial working‑condition requirements.

Accepts both analog remote set‑point and digital remote set‑point commands.
