Information About 2085-OW16

The Allen-Bradley 2085-OW16 is a Micro 800 relay output module. This module features Sixteen (16) AC /DC output channels that operates at nominal voltages such as 120VAC, 240VAC, 240VAC, 24VDC and 125VDC. This relay output module supports Micro 850 and Micro 870 controllers which directly installs to the right side of the Micro 850 and Micro 870 controllers.

This output module has a bus current draw of 160 mA @ 5VDC and 100 mA @ 24VDC with total power dissipation of 5.14 Watts. Each output point has a minimum load of 10 mA and Off-state leakage current of 1.5 A. This module comes with Sixteen (16) yellow indicators that are individually assigned to represent the energization state of each channel.

The 2085-OW16 comes with Two (2) removable terminal blocks. When wiring signal wires to the module, appropriate wire size is 0.25-2.5 mm2 (22-14 AWG) solid or stranded copper wire with insulation rating of 75 °C (167 °F ), or higher and maximum insulation thickness of 1.2 mm (3/64 in.). Strip insulation following the recommended stripping length of 10 mm or 0.39 inches. Tighten connection to the module’s terminal with Torque of 0.5-0.6 Nm (4.4-5.3 lb-in.). This module has an isolation voltage rating of 240V (continuous), Reinforced Insulation Type, channel to system Type tested at 3250V DC for 60s and pilot duty rating of C300, R150.

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
