Input Wiring & Isolation
The 32 inputs are grouped into two common points, allowing separate reference potentials within the same module. This sink-or-source flexibility means it can interface with both NPN and PNP sensors without reconfiguration. The input voltage range is 20.4...28.8 V DC, covering standard 24 V supplies with tolerance for brownout. Isolation at 500 V AC for 1 minute between channels and internal logic provides a baseline for system protection in grounded or mixed-voltage enclosures. For import and compliance documentation, the module’s status as obsolete may affect the availability of fresh RoHS or REACH declarations from the manufacturer; confirm with your sourcing desk prior to customs filing.
