Product characteristics

Serial communication interface

1734-485ASC is a single-channel, full-duplex serial interface module that supports RS-485 and RS-422 communication protocols.

This module allows the device to conduct ASCII data transmission with serial interface devices (such as barcode readers, PLCS, sensors, etc.) through the POINT I/O system, with a maximum transmission speed of 38.4 kbps.

POINTBus power Supply

This module is powered by POINTBus with a current of 75 mA. At 28.8 V DC, the maximum power consumption is 0.75 W and the maximum heat dissipation is 2.5 BTU/hr.

Installation method

The 1734-485ASC can be installed on the 1734-TB, 1734-TBS, 1734-TOP or 1734-TOPS terminal base units.

When installing, it is necessary to ensure that the module is correctly aligned with the rack and inserted into the fixed position.

Serial parameter configuration

Supports multiple serial character frame formats, including 7N2, 7E1, 7O1, 8N1, 8N2, 8E1, 8O1, 7E2, 7O2, etc.

The communication rates available are 9600 bps, 1200 bps, 2400 bps, 4800 bps, 19.2 kbps and 38.4 kbps.

Diagnostic function: The LED indicator lights on the module can be used to diagnose the module status, the POINTBus backplane status, as well as the sending and receiving status.

Supports on-board and channel-level data alarm (4 set values per channel), and provides engineering unit setting and channel-level diagnosis (electronic position and LED indicator light).

Compatibility: 1734-485ASC is typically used in conjunction with CompactLogix series PLCS such as 1769-L18ERM-BB1B and 1769-L24ER-QBFC1B, providing RS-485/422 ASCII interfaces.

This module supports the functions of RDF (Resource Description Framework) and AML (Automated Language Model), and is applicable to modern industrial automation systems.

Application scenarios

Industrial automation system

1734-485ASC is applicable to industrial automation systems that require ASCII data communication with serial devices such as barcode readers, sensors, actuators, etc.

It is commonly used in industries such as logistics, warehousing, manufacturing, and packaging to achieve efficient communication and data exchange among devices.

Remote monitoring and diagnosis: Through the POINT I/O system, the 1734-485ASC can achieve remote monitoring and diagnosis of serial devices, improving the maintainability and response speed of the system.
