Information About 2085-OW16

The 2085-OW16 is part of the Micro800 expansion I/O family, providing relay-based outputs suitable for switching AC or DC loads in small to midrange control systems. Its construction includes two removable terminal blocks and a reinforced-insulation design rated for continuous 240V isolation. The module integrates directly to the right side of supported Micro850 and Micro870 controllers, offering simple DIN-rail or panel mounting. Typical usage includes pilot devices, solenoids, contactors, and mixed-voltage loads that benefit from electromechanical relay isolation and broad voltage compatibility.

Key Features:

  • 16 AC/DC relay outputs: Supports a wide range of industrial voltages.
  • 2 A rating per channel: Suitable for switching small and medium loads.
  • Mixed-voltage capability: Operates at 120VAC, 240VAC, 24VDC, and 125VDC.
  • Compatible with Micro850/Micro870: Direct plug-in expansion for Micro800 controllers.
  • DIN-rail or panel mount: Flexible installation in compact control panels.
  • Reinforced isolation: Rated 240V continuous, type-tested at 3250VDC.
  • Per-channel LED indicators: Sixteen yellow LEDs for output status visualization.
  • Two removable terminal blocks: Simplifies wiring and maintenance.
  • Supported wire sizes: 0.25–2.5 mm² (22–14 AWG) copper conductors.
  • Low power consumption: Draws minimal 5V and 24V bus current from the controller.
  • C300, R150 pilot duty rating: Suitable for industrial relay applications.

The 2085-OW16 delivers the reliability and precision required for mixed-voltage relay output control in Micro800 automation systems.

Frequently Asked Questions about 2085-OW16
Question: What is the 2085-OW16?
Date Update:20/06/2025
Answer:

The 2085-OW16 is a 16-channel AC/DC relay output module for the Micro800 family (such as Micro850 controllers). It provides isolated relay outputs (up to 2 A) allowing the controller to switch higher-current loads independently for each channel.

Question: How do I wire the 2085-OW16?
Date Update:20/06/2025
Answer:
  • Module and RTB: Snap onto DIN rail using a Micro800 expansion RTB.
  • Field power wiring:
    Connect load supply (AC or DC) to terminal 1 (common) of RTB.
    Connect each output (channels O‑00 to O‑15) to respective terminals 2–17.
  • Load wiring:
    For DC loads: wire load between +24 V supply and the relay output terminal.
    For AC loads: wire between hot (L1) and relay output terminal.
  • Grounding & shielding: observe guidelines in publication 1770‑4.1 for signal integrity
  • Safety & ESD: Use antistatic precautions—ground yourself before handling
Question: What output voltage and signal scaling does the 2085-OW16 support?
Date Update:20/06/2025
Answer:
  • Each relay channel supports both AC or DC voltage switching.
  • Load voltage range: Up to 240 V AC or 24 V DC, depending on your application
  • Current handling: 2 A maximum per channel.
  • Signal scaling and mapping:
    In Connected Components Workbench (CCW), the controller reads each relay's state (On/Off) as a Boolean or an integer (0 for off, 1 for on).
    Scaling isn't applicable for relay outputs (digital outputs). To simulate analog behavior, you'll need to implement in PLC logic, e.g., use PWM or pulsing to approximate analog control.
Question: How do I protect relay outputs for long life?
Date Update:20/06/2025
Answer:

To extend relay life:

  • Use snubber circuits for AC inductive loads
  • Use flyback diodes for DC coils or solenoids
  • Avoid exceeding rated current/voltage
  • Use derating when switching frequently (>1 Hz) or when operating near temperature extremes
Question: Can I hot-swap the 2085-OW16 module?
Date Update:20/06/2025
Answer:

No. The 2085-OW16 does not support RIUP (Remove and Insert Under Power). You must:

  • Power down the controller and expansion bus
  • Remove the module
  • Re-energize only after proper reinstallation

This avoids arcing, possible relay damage, or controller faults
