More Information

Overview Manuals Output Group Load Limits Backplane Link Field Wiring

Features:

  • Switches eight 24 V DC field loads from one sourcing output group.
  • Maps controller output bits 0 through 7 directly to field terminals 0 through 7.
  • Uses a removable screw-terminal block and ribbon bus connector in the MicroLogix 1200 expansion assembly.
Allen-Bradley 1762-OB8 receives commanded output states from the MicroLogix 1200 expansion bus and presents them at eight field terminals.

The shared supply and common connections establish one output group, so all eight switched loads reference the same field-power boundary.

Point LEDs, labeled terminals, and the removable terminal block keep controller addressing, field wiring, and visible point state aligned during commissioning.

All prices are shown in USD.

Bit-to-Terminal Organization

  • Address map: Output data bits 0 through 7 correspond to terminals OUT 0 through OUT 7.
  • Shared supply: The +VDC terminal feeds the common source for all eight solid-state output paths.
  • Shared return: DC COM completes the field-power reference for the single output group.
  • Group isolation: The complete field group is isolated from the MicroLogix backplane.

Current and Switching Boundaries

  • Point current: Each point carries up to 1 A at 30 °C or 0.5 A at 55 °C.
  • Module current: The eight-point group carries up to 8 A at 30 °C or 4 A at 55 °C.
  • Switching delay: Resistive-load timing is limited to 0.1 ms on and 1.0 ms off.
  • Surge path: A point can carry the documented 2 A surge for 10 ms at the allowed repetition interval.

Controller and Field Separation

  • Bus connector: A short ribbon cable connects the module to the adjacent MicroLogix 1200 assembly.
  • Bus loading: The module draws its logic power from the 5 V backplane supply.
  • State transfer: Controller output words deliver the commanded on or off state to each field point.
  • Distance rule: The module position must remain within the six-slot power-supply distance rating.

Terminal and Mounting Practice

  • Conductor range: The screw terminals accept the documented solid or stranded copper wire sizes.
  • Terminal cover: The fingersafe cover stays in place while conductors are routed under the pressure plates.
  • Mounting direction: DIN-rail or panel installation is horizontal only.
  • Ventilation space: Clearance around the assembly protects airflow and access to the removable terminal block.
Description
Allen-Bradley 1762-OB8 is an eight-point 24 V DC sourcing solid-state output module for the MicroLogix 1200 expansion I/O system. It converts eight controller output bits into eight field switching paths arranged as one isolated output group.

Output data for Allen-Bradley 1762-OB8 uses bit positions 0 through 7, which correspond directly to output terminals 0 through 7. The shared +VDC and DC COM connections supply the group, while each output switches its assigned load from the common 24 V DC source.

Through its ribbon bus connector, Allen-Bradley 1762-OB8 receives backplane power and controller-directed output states from the adjacent MicroLogix assembly. Group-to-backplane isolation separates the field output circuit from the controller bus, but the eight points remain electrically organized as one field group.

The removable terminal block on Allen-Bradley 1762-OB8 accepts solid or stranded copper conductors and can remain covered during normal wiring. The module mounts horizontally on DIN rail or a grounded panel, with surrounding clearance reserved for ventilation and wiring access.
