ArmorBlock I/O Modules

Our Bulletin 1732D and 1732E ArmorBlock® I/O modules provide low-cost, hardened, I/O suitable for on-machine use. You can mount these modules on a machine close to the sensors and actuators to provide shorter cable runs for automotive, material handling, and high-speed packaging applications. These modules are available for DeviceNet® and EtherNet/IP™ networks and are suitable for use in welding applications and end-of-arm robot applications.
