The 1792D-8BIO8E is a standalone combo I/O module from the ArmorBlock MaXum family, offering 8 input channels and 8 output channels in a single compact unit. This 24 V DC device communicates over the DeviceNet network, serving as a distributed I/O node for machine‑side automation. The inputs feature 24 V DC sinking voltage, while the outputs are self‑protected and deliver up to 0.3 Amps each. Output power is sourced internally from the DeviceNet supply, simplifying external wiring requirements. Additionally, the module includes built‑in local logic control and short‑circuit protection with block‑level notifications. Its loopback connection design enhances noise immunity, ensuring reliable signal integrity. Therefore, the 1792D-8BIO8E delivers robust, space‑efficient I/O solutions for demanding industrial environments.
The 1792D-8BIO8E provides 8 inputs and 8 outputs with distinct characteristics. Input channels operate at 24 V DC sinking voltage, compatible with standard PNP sensors. Outputs are self‑protected 24 V DC sourcing type, delivering a maximum of 0.3 Amps per channel. The module draws its output power directly from the DeviceNet network, eliminating the need for a separate auxiliary supply. I/O connections use loopback formations, where return wires connect back together to maximize noise immunity. Short‑circuit protection is included on both inputs and outputs, with notifications reported at the block level. Furthermore, the module supports polled, change‑of‑state, or cyclic connections for flexible data exchange with the DeviceNet master. This versatility makes the 1792D-8BIO8E suitable for a wide range of control applications.
One notable feature of the 1792D-8BIO8E is its built‑in local logic control capability. This allows the module to execute simple logic operations without relying on the network master, enabling faster response times for time‑critical tasks. The module exchanges I/O data with the master device via three communication modes: polled, change‑of‑state, or cyclic. In cyclic mode, the 1792D-8BIO8E produces its I/O data at a configured rate, functioning as a Client I/O node. This flexibility accommodates different application requirements, from high‑speed polling to event‑driven updates. Consequently, engineers can optimize network bandwidth and system performance based on their specific needs.
This rugged module weighs 0.54 kg and features a sealed housing that meets IP67 standards. It resists dust and temporary water immersion, allowing direct mounting on machines without additional enclosures. Operating temperatures range from ‑25°C to 60°C, while storage temperatures span up to 80°C. The module is ESD‑sensitive, so proper handling precautions are necessary during installation. The single‑connector design for both input and output simplifies wiring, though loopback connections require return wires to be joined together. This configuration ensures maximum noise immunity, which is critical in electrically noisy industrial settings. The 1792D-8BIO8E also complies with EMC standards EN 50081‑1 and EN 50082‑2 for industrial environments.
Installing the 1792D-8BIO8E requires careful attention to wiring and sealing. First, mount the module securely onto the machine or cable base using its integrated mounting holes. Next, connect the DeviceNet network cable and ensure proper termination to avoid signal reflections. Then, wire the inputs and outputs in loopback formations, connecting return wires back together to maximize noise immunity. This practice is essential for achieving reliable signal integrity in noisy environments. Tighten all connectors and caps securely to maintain the IP67 seal and protect against moisture ingress. Additionally, use properly terminated cables to minimize noise disturbances. After wiring, assign a unique node address using the rotary selector. Finally, power up the module and verify normal operation through the status indicators.
