The Allen-Bradley 1734D-IA8XOW8S is a Point I/O ASCII Interface module. It creates a flexible DeviceNet interface for RS-232 ASCII devices. Its voltage range is 10 - 28.8V DC, its current supply is 10A at 24V DC, and its maximum power dissipation is 2W. It has 8 AC inputs and 8 relay outputs. It has dimensions of 3 x 2.36 x 5.25 in. The 1734D-IA8XOW8S has an external AC power supply of 120V at 60Hz and a Form A relay type. The PointBus expansion port allows the addition of maximum 12 I/O modules. The 1734D-IA8XOW8S is ideal for applications where flexibility and low cost are important for the system design and operation. Its diagnostics and configurable features make it easy to use. It has applications in local control panels, remote device panels, and it is accessible from many locations.

The 1734D-IA8XOW8S module has various features that facilitate installation and operation. It has a compact, flexible design that allows it to fit into minimal panel space. The 1734D-IA8XOW8S can mount on a DIN rail easily and be uninstalled easily by sliding the components together. The module can be mounted vertically or horizontally. I/O modules, machines feature, and a network interface can be added without making any changes with the Auto Device Replacement (ADR) feature. To increase performance, the I/O use Change-of-State connections. The Removal and Insertion Under Power (RIUP) feature allows replacement while the system is running. During installation and troubleshooting, the removable wiring system saves time and money.

The 1734D-IA8XOW8S module uses DeviceNet interfaces, EtherNet/IP, and PROFIBUS DP adapters. It can also use DeviceLogix technology. For safety from short-circuiting, there is an output point status indicator for warning signs.

It has a 120V AC, 60 Hertz external power supply and a relay of form A N.O, SPST with a load minimum of 10 milliamps/point. This POINTBlock AC Input/Relay Output Module can support 12 maximum expansion modules.
