Information About 1756-OW16I
The 1756-OW16I is part of the ControlLogix family, designed for use in Rockwell Automation’s ControlLogix chassis-based systems. It functions as a dry-contact relay output module, offering high flexibility by supporting output currents of 1 A at 5–30V DC, 0.5 A at 48V DC, 0.22 A at 125V DC, 1.5 A at 120V AC, and 0.75 A at 240V AC. Each channel is individually isolated, improving noise immunity and ensuring reliable operation in demanding environments. The module has a maximum output delay of 10 ms per transition and a switching frequency of up to one operation every three seconds at rated loads. It includes features such as scheduled outputs and configurable response during program or fault mode (Hold Last State, On, or Off). With backplane current consumption of 150 mA at 5.1V and minimal current draw at 24V, its overall power dissipation is 4.5 W at 60 °C. The 1756-OW16I is compatible with removable terminal blocks (1756-TBCH or 1756-TBS6H), allowing easier wiring and maintenance.
Key Features:
- Output Channels: Sixteen (16) individually isolated relay outputs with Normally Open (N.O.) contact form.
- Operating Voltage: Supports wide ranges of 5–125V DC and 10–240V AC for diverse applications.
- Output Current Ratings: Delivers 1 A @ 5–30V DC, 0.5 A @ 48V DC, 0.22 A @ 125V DC, 1.5 A @ 120V AC, and 0.75 A @ 240V AC.
- Switching Frequency: Rated at 0.3 Hz (one operation every three seconds) at full load with mean contact bounce of 1.2 ms.
- Output Timing: Maximum ON-to-OFF and OFF-to-ON delays of 10 ms per channel.
- Fault/Program Response: Configurable to Hold Last State, turn Off, or remain On during fault or program mode.
- Backplane Requirements: Draws 150 mA @ 5.1V DC and 2 mA @ 24V DC, with 4.4–4.5 W maximum power dissipation.
- Installation: Supports removable terminal blocks (1756-TBCH, 1756-TBS6H) for simplified wiring and replacement.
The 1756-OW16I delivers the flexibility, durability, and reliability required for industrial control applications involving AC and DC load switching.
