Allen-Bradley |1771-OWNA| 32-Channel Contact Output Module
Description
The 1771-OWNA is a 32-channel contact output module designed for industrial control systems, suitable for switching resistive loads. It must be installed in a 1771-A1B through -A4B or later I/O chassis and is not recommended for inductive or capacitive loads.
Features
- 32 Outputs: Arranged in 4 groups of 8 outputs each with individual commons.
- Load Capacity: Each output can handle up to 1.0A continuous load at 30W maximum.
- Power Factor: AC loads should have a power factor of 1.0.
- Cable Length: Maximum interconnect cable length is 1000 feet (304.8 meters).
Technical Specifications
- Outputs per Module: 32 (4 groups of 8)
- Voltage Rating: 24 to 138V AC RMS, 24 to 125V DC
- Current Rating: Max 1A per channel (derates linearly above 45°C), max 12A per module
- Power Rating: 30W per output (resistive) maximum for both DC and AC
- Operate/Release Time: 5ms typical (+1ms)
- Bounce Time: 1ms maximum
- Switching Frequency: 10Hz maximum
- Backplane Current: 2.5A maximum, 1.8A nominal
- Isolation Voltage: 1000V between open contacts, 1500V coil to contact
- Environmental Conditions: Operating temperature 0 to 60°C, storage temperature -40 to 85°C, relative humidity 5% to 95% non-condensing
- Field Wiring Arm: Cat. No. 1771-WN, screw torque 7-9 inch-pounds
- Keying: Between slots 6 and 8, 16 and 18
