The 1794-OA16 provides a robust solution for controlling AC loads. This module switches sixteen outputs with a voltage range of 74-132VAC. It energizes relays, solenoids, contactors, and pilot lamps effectively. Engineers choose this module for its reliable high-current capacity. The module delivers a maximum output current of 4.0 Amps. Each channel handles up to 500 mA at 55 degrees Celsius. This performance makes it ideal for demanding factory floor applications.
Expert Technical Performance Review
The module offers precise switching with a maximum signal delay of just one-half cycle. This ensures fast response for time-critical processes. The on-state voltage drop remains low at 1.5 Volts. This reduces power loss across the output circuit. The off-state leakage current stays at a maximum of 2.25 mA. This prevents unintended activation when the output is off. The isolation voltage is rated at 120 Volts continuous. This protects downstream equipment from electrical faults. The module’s power dissipation reaches a maximum of 4.7 Watts. Its thermal dissipation is 16.1 BTU per hour. These specifications confirm efficient thermal management.
The module operates reliably in harsh environments. Its temperature range spans from 0 to 55°C (32 to 131°F). It withstands storage temperatures from -40 to 85°C. The unit handles vibration of 5G at 10 to 500 Hertz. It survives operating shocks of 30G and non-operating shocks of 50G. An ESD immunity level of 8kV air discharge adds protection. The open-type enclosure allows for proper ventilation. This rugged design ensures long service life in industrial settings.
Product Procurement & Buyer Guide
The 1794-OA16 requires a compatible Flex I/O terminal base for operation. It works with models like 1794-TBN, 1794-TBNF, and 1794-TB3. It also supports 1794-TB2, 1794-TB3S, and 1794-TBKD bases. Each terminal base provides the physical connection for field wiring. The module draws only 80 mA from the FlexBus at 5VDC. This low current draw minimizes the load on the backplane power supply. The module includes a built-in MQ2 fuse rated at 2.5A. This fuse protects the internal circuitry from overcurrent conditions.
Procurement teams should verify the base model carefully. The 1794-TBNF base requires auxiliary blocks for common voltage connections. Using the correct base simplifies installation and reduces wiring errors. The module’s keyswitch position is 8, which ensures proper alignment. This prevents incorrect module insertion into the base. The module weighs just 96 grams for easy handling during installation. All these features simplify the specification and purchasing process for engineers.
