ArmorBlock

The Allen-Bradley ArmorBlock I/O family (Bulletins 1732, 1732E, 1732IL) delivers distributed, block-style discrete I/O modules engineered for direct machine-mount in harsh industrial environments, communicating natively over EtherNet/IP. The catalog number encodes key configuration at a glance: the bulletin prefix (1732E for EtherNet/IP-connected blocks, 1732IL for IO-Link hub variants) is followed by a direction/type code — IB for DC sinking inputs, OB for DC sourcing outputs, or CFG for self-configurable points — then a point count (8 or 16), connector style (M8 or M12), and suffix flags such as SR for scheduled outputs, SOE for Sequence of Events, and DR for dual-port ring topology support. Representative models include the 1732E-IB16M12R (16 sinking inputs, M12 connectors), the 1732E-OB16M12R (16 sourcing outputs, M12), the 1732E-OB8M8SR (8 scheduled sourcing outputs, M8), and the 1732IL-IB16M12 IO-Link Class A hub with 16 digital inputs. The family spans 40 catalog numbers, including self-configurable and embedded I/O variants, giving machine builders flexible point counts and connectivity options without a separate field-wiring enclosure.
