Information About 1734-232ASC

The 1734-232ASC is a POINT I/O interface module functioning as an ASCII communication module. This module is typically used for interfacing barcode readers located in the Point of Sale (POS) or within the manufacturing line. It can be used to implement automated sorting and quality assurance systems. This module comes with an RS232 interface that supports 9600, 1200, 2400, 4800, 19.2k, and 38.4k communication speeds. The 1734-232ASC is mounted to a wiring base assembly such as 1734-TB or -TBS w. It has backplane or PointBus current draw of 75mA @ 5V dc; Power Dissipation of 0.75W maximum @ 28.8V dc and Thermal Dissipation of 2.5 BTU/hr maximum @ 28.8V dc. It operates when wired to an external power supply voltage that provides a 10-28.8VDC voltage range with a nominal supply voltage of 24 VDC. It requires a supply current of 15mA @ 24V dc with integrated fault protection rated at 28.8 VDC. The module’s serial parameters include character framing of 7N2, 7E1, 7O1, 8N1, 8N2, 8E1, 8O1, 7E2, 7O2. The serial port received from ASCII device has a maximum number of 128 characters; Receive record start mode settings of No, exclude, include start delimiter; Receive Start Delimiter settings of ASCII character; Receive Record End Mode of No, exclude, include end delimiter, and Receive End Delimiter of ASCII character. This module comes with status LED indicators such a One (1) green/red module status indicator at the logic side; One (1) green/red network status indicator at the logic side and Two (2) green TXD, RXD status indicators at the logic side.

The Allen-Bradley 1734-232ASC is a POINT I/O communication interface module. This module has an RS232 interface that supports ASCII communication. It is ideally used for communicating with ASCII devices such as a barcode reader. For industrial applications, barcode reader are typically used in industrial manufacturing machines, scanning products to properly identify and sort products and used for quality control applications. The 1734-232ASC comes with a single RS232 interface that supports full-duplex communication. It supports serial character framings such as 7N2, 7E1, 7O1, 8N1, 8N2, 8E1, 8O1, 7E2, and 7O2 and transmission rates of 9600, 1200, 2400, 4800, 19.2k, and 38.4k. For ASCII communication, it can receive a maximum number of 128 characters; No, exclude, include start delimiter Receive Record Start Mode settings; ASCII character start delimiter; No, exclude, include start delimiter Receive Record end Mode settings as well as ASCII character end delimiter. The 1734-232ASC comes with One (1) green/red module status indicator, One (1) green/red network status indicator and Two (2) green TXD, RXD status indicators. It is compatible for use with 1734-TB or -TBS wiring base assembly. When mounting to the mentioned terminal bases, appropriate keyswitch position is 2. It has a POINTBUS current draw of 75mA @ 5V dc, power dissipation of 0.75W maximum @ 28.8V dc, and Thermal Dissipation of 2.5 BTU/hr maximum @ 28.8V dc. This module requires an external DC power with nominal voltage of 24VDC while the applicable input voltage range is 10-28.8 VDC. The module’s supply current requirement is 15mA @ 24VDC and comes with fault protection at 28.8V dc. The 1734-232ASC is suitable for applications where flexibility and low cost are important for system design and operation. Its comprehensive diagnostics and configurable features make running applications with it easy. The 1734-232ASC module has benefits that facilitate installation and operation, including a compact, flexible design that allows it to take up limited panel space. It is a DIN rail mounted device which is easily installed and uninstalled by sliding the components together. The module can be mounted vertically or horizontally. I/O modules, a machine feature, and network interface can be added without making any changes with the auto device replacement (ADR) feature. The 1734-232ASC also supports use change-of-state connections. The removal and insertion under power (RIUP) feature allows the users to make replacements without powering down the machine. For efficient communication, the 1734-232ASC module uses DeviceNet interfaces, EtherNet/IP, and PROFIBUS DP adapters. It is also available with DeviceLogix technology for smooth integration. For protection from short-circuiting, an output point status indication is present.
