The Allen-Bradley 1734-232ASC is a POINT I/O ASCII communication interface module. It directly connects barcode readers and serial devices to control systems. This module supports full-duplex RS232 with speeds from 1200 to 38.4k baud. Its compact, DIN-rail design saves valuable panel space while delivering reliable data capture for sorting and quality assurance.
Product Procurement & Buyer Guide
The 1734-232ASC solves critical pain points for procurement managers and application engineers. It integrates ASCII devices like barcode scanners into manufacturing lines without complex programming. The module accepts a wide voltage range of 10-28.8 VDC, making it compatible with most 24V industrial supplies. Its power dissipation is only 0.75W, reducing thermal load in cabinets.
Engineers appreciate the module's flexible serial framing support. It handles 7N2, 7E1, 7O1, 8N1, 8N2, 8E1, 8O1, 7E2, and 7O2 configurations. This ensures seamless pairing with diverse legacy equipment. The unit draws just 15mA at 24V DC and has a PointBus current of 75mA at 5V. Such low power consumption lowers operational costs over time.
Procurement teams value the module's auto device replacement (ADR) feature. It allows hot swapping without reconfiguration, minimizing downtime. The removal and insertion under power (RIUP) capability further boosts system availability. These factors make the 1734-232ASC a cost-effective choice for continuous production environments.
Step-by-Step User & Installation Guide
Mount the 1734-232ASC onto a compatible wiring base assembly. Use the 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS base. Ensure the keyswitch position is set to 2 for correct alignment. Slide the module onto the DIN rail until it locks securely. You can mount it vertically or horizontally, depending on cabinet layout.
Wire the external DC supply within the 10-28.8 VDC range. Connect the RS232 port to your ASCII device using a full-duplex cable. Configure the baud rate (1200, 2400, 4800, 9600, 19.2k, or 38.4k) and framing parameters in your control software. The module accepts start/end delimiters and can handle up to 128 characters per record.
Verify operation using the status LEDs. A green/red module status indicator shows power and fault conditions. Two green TXD/RXD LEDs confirm data transmission. The network status indicator links to the backplane communication. For replacement, simply remove the module under power using the RIUP feature, then insert a new unit without restarting the system.
