The 6AG1321-7BH01-4AS0: 16 digital inputs, 24 V DC, with parameterizable input delay (0.1, 0.5, 3, 15, or 20 ms) lets you filter contact bounce or fast sensor edges. Wire-break detection triggers below 1 mA. Diagnostic and hardware interrupts are parameterizable — useful for rapid fault localisation. Requires a 20-pin front connector. Temperature range -40 to 70 °C covers unheated cabinets and outdoor enclosures.
It operates from -40 °C to 70 °C, covering most industrial and outdoor conditions.
UL File E239877, CE, KC, EAC, and RCM. Isolation tested at 500 V DC.
Yes, it is parameterizable to 0.1, 0.5, 3, 15, or 20 ms.
Yes, it detects wire-break when current falls below 1 mA, and can trigger a diagnostic alarm.
