Storage temperature: -40°C to 85°C.

Relative humidity: 5% to 95% (non-condensing).

Vibration: 2 g (10-500 Hz).

Impact: 30 g (in operation), 50 g (not in operation).

Battery: Built-in lithium battery, with a lifespan of approximately 2 years (supports RAM data retention).

Installation: Insert the SLC 500 chassis (1746-A4, A7, A10, A13) into any slot (except slot 0).

Certification: UL, C-UL, CE, Class I Div.2 (Group A/B/C/D, T4).

Function

BASIC program execution:

Run the BASIC 52 program to support complex calculations, data processing and custom logic.

It can interact with the SLC processor (via the backplane) or external devices.

Flexible communication

The three communication ports support the protocols RS-232, RS-422, RS-485, DH-485 and DF1.

Port 1 is used for programming or HMI, port 2 is used for DH-485 networks, and port 3 is used for external devices (such as barcode scanners, printers).

Data collection and storage

I/O data is collected and processed through the BASIC program and stored in 8 KB RAM or optional EEPROM/UVPROM.

Support interaction with SLC data tables (reading/writing integers, floating-point numbers, timers, etc.).

Modular expansion

Compatible with the SLC 500 chassis and working in coordination with other I/O modules.

Support external storage modules and expand program capacity (up to 32 KB).

Diagnosis and Configuration

Provide LED indicator lights (power, communication, fault) to monitor the status in real time.

Configure and debug the BASIC program through RS-232 using terminal software (such as HyperTerminal).

Third-party device integration: Connect printers, displays, modems and other devices via ASCII or custom protocols.

Application scenarios

Manufacturing industry: Handle complex calculations or custom logic (such as quality control, data logging), and connect barcode scanners or displays.

Process control: It is used in water treatment, chemical engineering or pharmaceuticals to collect sensor data and generate reports.

Material handling: Manage sorting or storage systems and communicate with external equipment (such as weighing systems).

Packaging: Control the packaging machine, record production data and output it to the printer via ASCII.

OEM equipment: Integrated into dedicated machinery (such as test equipment) to perform specific algorithm or protocol conversions.

Building automation: Connect to HVAC or energy management systems and process data from external devices.

Typical applications:

Small and medium-sized systems that require BASIC programming, involving data acquisition, custom communication or integration with third-party devices.

Expand the functions of the SLC 500 system to handle non-standard protocols or complex computations.
