Technical Specifications

Engineering Advantages

Versatile AC/DC Load Switching
The 2085-OW16 offers exceptional flexibility by supporting a broad operating voltage range, including 24V DC, 125V DC, 120V AC, and 240V AC. This allows automation specialists to control diverse field devices—from low-voltage DC solenoids to high-voltage AC motor contactors—using a single expansion module, significantly simplifying spare parts inventory and panel design.

High-Density Output Expansion
By providing 16 independent relay outputs in a compact footprint, this module maximizes the control capability of Micro850 and Micro870 systems. Each channel handles up to 2A, making it ideal for applications requiring numerous discrete control signals without the need for bulky external interface relays.

Electrical Isolation and Safety
Mechanical relay outputs provide inherent electrical isolation between the PLC logic side and the field wiring. This robust isolation protects the sensitive controller electronics from voltage spikes, electrical noise, and shorts on the load side, ensuring the longevity and stability of your automation system in electrically noisy industrial environments.

FAQs

Q: Which PLC controllers are compatible with the 2085-OW16?
A: This expansion module is specifically designed for the Allen-Bradley Micro800 family. It is fully compatible with Micro850 and Micro870 controllers, allowing for seamless system expansion.

Q: What is the voltage and current rating for the outputs?
A: Each of the 16 relay outputs is rated for 2 Amps. The module supports a versatile voltage range, including 24V DC, 125V DC, 120V AC, and 240V AC, accommodating both AC and DC loads.

Q: How much power does this module draw from the PLC bus?
A: The 2085-OW16 draws 120 mA at 5.0V DC and 50 mA at 24V DC from the controller's backplane bus. Ensure your power budget accounts for this consumption when designing your system.

Q: What type of wire should be used for installation?
A: You should use solid or stranded copper wire rated at 75°C (167°F) or greater. The acceptable wire size ranges from 0.25 to 2.5 mm² (22 to 14 AWG) with a maximum insulation diameter of 1.2 mm.
