• Output Configuration: 8 nonisolated outputs with 240V AC nominal voltage (range 159-264V AC).
• Current Ratings: 4.0A total per module; 500mA maximum per output at 55°C.
• Electrical Characteristics: 1.5V AC max on-state voltage drop @ 0.5A; 2.5mA max off-state leakage.
• Isolation & Power: 250V continuous isolation; draws 60mA @ 5V DC from FlexBus.
• Thermal Management: Dissipates 5W (17.1 BTU/hr) max power at 0.5A load.
• Environmental Tolerance: Operates at 0 to 55 °C (32-131 °F) with 5-95% noncondensing humidity.
• Status Indication: 16 yellow LEDs clearly show channel output states for easy diagnostics.

Installation and Mounting Guidelines

• Snap the 1794-OM8 onto a DIN rail using compatible terminal bases like the 1794-TBN or 1794-TBNF.
• Mount the module directly onto the terminal base to establish a connection with the I/O bus and field wiring.
• You can remove or insert the module while the system remains powered, ensuring zero downtime.
• Choose extreme-environment (XT) versions of the 1794-OM8 for applications requiring wider temperature or vibration tolerance.

Frequently Asked Questions (FAQ)

• What is the maximum on‑state voltage drop for the 1794-OM8?
  The maximum on‑state voltage drop is 1.5V AC at 0.5A per output. This ensures low power loss during operation.
• Can I use this module with 120V AC systems?
  Yes, the 1794-OM8 operates within 159‑264V AC, so it works with both 120V and 240V AC applications.
• What network adapters are compatible with the 1794-OM8?
  You can connect it to any 1794‑series Flex I/O adapter, including those for EtherNet/IP, ControlNet, DeviceNet, and Universal Remote I/O.
• What is the off‑state leakage current of this output module?
  The maximum off‑state leakage is only 2.5mA, preventing false activation of sensitive loads.
• Does the module come with a terminal base?
  The package includes only the 1794-OM8 module. You need to order the terminal base (e.g., 1794‑TBN) separately.
• How fast do you ship the 1794-OM8?
  We dispatch within 5 working days via FedEx, UPS, or DHL, depending on your location.
