Product Overview
The 1734-IB2 is a compact, high-performance 24 VDC Digital Sinking Input Module engineered by Allen-Bradley (Rockwell Automation) for the versatile POINT I/O System. Built to facilitate seamless field device connectivity across ControlNet, DeviceNet, and EtherNet/IP networks, this module features Two (2) discrete sinking input channels designed to monitor 24V DC logic signals in industrial automation systems. Operating across a field supply range of 10 to 28.8 VDC (24 VDC nominal) with a maximum input current of 5 mA per channel, it mounts onto a designated removable terminal block (RTB) base with a mechanical keyswitch set to Position 1. Featuring an ultra-lightweight hardware net weight of 30.9 g (0.0309 kg / 1.09 oz), an open-style enclosure rating, and an extended operating temperature range from -20°C to +55°C, this module draws just 75 mA of POINTBus backplane current at 5V DC.
As depicted in the product image, the module features a slice form-factor with integrated diagnostic LEDs, side mounting latching mechanisms, and precise terminal base alignment slots for quick vertical or horizontal installation.
Core Technical Advantages
- Flexible Multi-Network Connectivity: Integrates effortlessly into distributed architectures managed via EtherNet/IP, ControlNet, DeviceNet, and other open industrial network protocols.
- Low-Power Sinking Inputs: Features 2 sinking input points with low heat generation, consuming only 0.7 W maximum power dissipation at 28.8 VDC for improved panel thermal management.
- Mechanical Keyed Safety Base: Designed for mechanical Keyswitch Position 1 on the mounting base to prevent module misplacement during installation and field replacement.
- Versatile Enclosure Mounting: Open-style slice housing supports both horizontal and vertical mounting orientations without thermal derating up to 55°C.
