🏭 Typical Applications
Connect clusters of weld-cell clamps, part-presence photoeyes, and pneumatic valve manifolds directly on robotic end-of-arm tooling (EOAT). The IP67 hub tolerates harsh environments and weld spatter while consolidating dense I/O.
Manage hundreds of optical sensors and motorized roller drives across vast distribution center lines. These hubs significantly reduce the physical cabling required for long-distance sensor tracking.
Simplify the wiring of discrete guard-door interlocks, stack lights, and pneumatic cylinders. Cluster them locally on the machine frame instead of running every single wire back to a main control cabinet.
Consolidate temperature, pressure, and fluid-level switch signals within tight, lubricant-heavy machining enclosures. Keep your control cabinet clean and your field wiring protected.
FAQ
Q1. What is the difference between the PM8 and NM8 models?
A: The PM8 model supports PNP (positive switching) sensors, which are standard in most European and domestic Chinese machinery. The NM8 model supports NPN (negative switching) sensors, often found in older systems or specific Asian markets. Please check your sensor type before ordering.
Q2. Can I use this hub to control outputs (actuators)?
A: No, the SG-IO-IOL-16DI is an Input-only module (16DI). It is designed to read signals from sensors (like proximity switches or photoelectric sensors). If you need to control valves or relays, please look at our 16DIO (Digital Input/Output) series.
Q3. How far can I place this hub from the IO-Link Master?
A: You can place the hub up to 20 meters away from the IO-Link Master using a standard unshielded 3-wire cable. This allows you to place the I/O directly next to the sensors, saving significant cabling costs back to the main control cabinet.
Q4. Is this module compatible with Siemens or Allen-Bradley PLCs?
A: Yes. Since this hub complies with the standard IO-Link V1.1 protocol, it is vendor-neutral. It works with any PLC that has an IO-Link Master card or module (e.g., Siemens S7-1200/1500, Rockwell Allen-Bradley, Beckhoff, Omron, Mitsubishi).
