✅ Core functionality
32 point high-density DI acquisition single slot 32 point 24VDC switch input, collecting proximity switch, photoelectric switch, limit, button signals; Supports NPN and PNP sensors, with flexible wiring.
Four electrical isolation groups, four independent common terminals, isolated between groups; Different groups can be connected to different reference potentials, and a short circuit in one group will not affect the other channels, thus resisting on-site interference.
The software can configure the input filtering time in Proficy ME to suppress on-site jitter and electromagnetic interference; 1ms is used for high-speed working conditions, and 7ms filtering is applied for strong interference on site.
The channel LED status indicator does not require software on site, and can directly judge the quality of the sensor signal by looking at the light, which is convenient for troubleshooting.
🛠 Typical application scenarios
The assembly line sorting and conveying equipment has a large number of photoelectric, in place detection, and feedback on blocking positions; High density DI saves slot space, with 4 sets of isolation to group power supply for safety signals and ordinary detection signals.
Packaging and filling automation production line material level switch, cylinder magnetic switch, and workstation position feedback collection.
Machine tools, assembly tooling equipment limit switches, safety doors, emergency stop feedback, and operation panel button signal acquisition.
Replacement of RX3i system spare parts for maintenance of new and old RX3i equipment; Both new and second-hand dismantling markets are in circulation.
⚠️ Usage Precautions
Screw free terminals must use specialized flat cables IC694CBL327/IC694CBL328 and cannot be directly wired.
When installed on the serial expansion backplane (CHS392/398), the module is prohibited from hot plugging and unplugging, as live plugging and unplugging can cause system failure.
The PCI slot of the host rack supports hot swapping; Extended serial rack is not supported, this should be distinguished.
