Product Description

The 1756-OB16IS is a digital output execution component built for the ControlLogix system configuration. It functions within a nominal 12/24V DC voltage envelope, featuring 16 channels that are isolated individual points designed to secure downstream circuitry against cross-signal disturbance and transient spikes. This module integrates 8 scheduled output points designed to enable precise synchronization matching coordinated machine sequences with reference to the Coordinated System Time. It installs inside standard control slots, interfacing with industrial field loads via specified removable termination assemblies to provide deterministic actuation and steady processing states under multiple manufacturing control configurations.

Features

  • Incorporates 16 isolated output channels providing basic insulation between output points and backplane circuits.
  • Features 8 scheduled outputs allowing time-stamped task performance linked directly with coordinated control architecture.
  • Provides sinking or sourcing load matching with an execution range spanning 10V DC to 30V DC field operations.
  • Delivers continuous visual verification of independent output channel execution states and module hardware health.
  • Supports electronic, software-configurable keying options to enforce accurate hardware module matching upon slot replacement.

Applications

  • High-speed sorting and discrete tracking machinery requiring timed sequence control.
  • Solenoid valve switching loops and isolated pilot relay driving circuits.
  • Multi-zone industrial heating elements requiring synchronized control pulses.

Installation Guidelines

  • Ensure conductor routing follows specified guidelines for Wire Category 1 paths to reduce crosstalk with high-voltage power components.
  • Use only approved ControlLogix Removable Terminal Blocks, specifically models 1756-TBCH or 1756-TBS6H, to wire external field outputs.
  • Set the software-based electronic keying attributes accurately within the project configuration to prevent mismatched module replacement errors.
  • Apply appropriate current derating factors when operating ambient conditions rise, limiting per-point current to 1 A when reaching 60 degC.
  • Mount the open-style chassis assembly inside an enclosure that offers appropriate protective barrier sealing against environmental particulates.

FAQ
What is the continuous isolation threshold provided by the device?
The device provides a continuous isolation voltage rating of 250V using basic insulation across outputs-to-backplane and output-to-output connection paths.
How do environmental conditions affect the maximum current allowance per point?
The maximum current per point is rated at 2 A when operating under an ambient temperature up to 30 degC, which then derates linearly down to 1 A as the temperature reaches 60 degC.
What happens to the outputs when the controller switches into Fault or Program mode?
Each output channel can be configured to hold its last state, turn On, or turn Off. The default parameter configuration enforces an Off state for both modes.
