It complies with the requirements of contamination level 2 and overvoltage category II of IEC 60664-1

Function

ASCII device interface:

Provide a communication interface with devices that support the ASCII protocol, such as barcode readers, printers, weighing instruments or other serial communication devices.

Two independent and isolated ASCII ports support simultaneous communication with different devices. Port 1 (RS-232/RS-422) and port 2 (RS-485) can be configured independently.

Flexible communication configuration:

Supports full-duplex (RS-232) and half-duplex (RS-422/RS-485) communication modes.

Configurable baud rate (300 bps to 115,200 bps) and data format (ASCII, Modbus ASCII, DF1) to meet the requirements of various devices.

Automatic data format recognition simplifies the configuration process.

Seamless integration

Compatible with CompactLogix and MicroLogix 1500 controllers, it can be directly connected to the controller or other 1769 modules via the backplane without the need for an external power supply.

Supports direct connection with PowerFlex drives or other devices via Compact I/O to DPI/SCANport or DSI/Modbus modules.

Status monitoring

It is equipped with LED status indicator lights to display the power supply, communication status of the module and the activity status of each channel, facilitating on-site diagnosis.

Operating status indication: No power/not configured (no indication), operating mode (green constantly on, red flashes once when starting).

Installation and maintenance

Supports DIN rail or panel installation, suitable for compact Spaces.

Configuration is carried out through RSLogix 5000 or Studio 5000 software to simplify the Settings of I/O memory mapping and communication parameters.

Application scenarios

Industrial Automation

Barcode scanning: It is used in the barcode reader interface of factory automation to read product information (such as manufacturing date, batch number, expiration date, etc.), and is widely applied in packaging, logistics and warehousing systems.

Data collection: Collect data from serial devices such as sensors, flow meters, and weighing instruments for real-time monitoring and process optimization.

Device control: Send ASCII commands to programmable controllers, drivers or other external devices to control device operations, such as adjusting motor speed or setting parameters.

Human-machine Interface (HMI) : Connected to HMI devices, it is used for operator display and data interaction, providing real-time process data or operation instructions.

Remote communication: Communicating with remote devices through a modem, suitable for scenarios where remote data collection or control is carried out via telephone lines.

Traditional system integration: Integration with legacy PLCS or other serial-based controllers for system upgrades or hybrid control architectures, maintaining compatibility with existing equipment.

Small and medium-sized applications: Suitable for small and medium-sized automation projects that require low-axis motion control and I/O points, such as small production lines, test equipment, or laboratory automation.
