1734-OW2

The 1734-OW2 from Allen Bradley is a relay output module, categorized within the Point I/O 1734 series. This unit is engineered to operate with two outputs, each utilizing normally open Form A electromechanical relays. It is critical for managing output control effectively in various automation configurations.

This module demonstrates an off-state leakage current of 1.2 amperes when functioning at 240 VAC, ensuring that minimal energy loss occurs during idle periods. Each relay channel can handle a maximum contact current of 2.0 amperes, allowing for significant versatility in load management during operation. Power consumption for the module is rated at 0.8 watts, while the backplane draws 80 milliamperes at 5 volts DC, indicating efficient power handling.

Also noteworthy is the power dissipation, capped at 0.5 watts, which contributes to the device's overall efficiency. The isolation voltage of the unit is set to 250 volts, enhancing safety and effectiveness within electrical systems. This module also boasts a maximum switching frequency of one operation every three seconds, which translates to 0.3 Hz at rated load.

Durability is a hallmark of the 1734-OW2's design; it has an expected contact life exceeding 100,000 operations at rated load. The compatibility of wire sizes ranges from 0.25 mm² to 2.5 mm², accommodating both solid and stranded copper conductors in the 22 to 14 AWG range.

This device is built open style with no specific enclosure rating, making it suitable for controlled environments. In terms of thermal performance, the module can operate effectively within temperatures from -20 to 55 degrees Celsius and is rated for storage in conditions as extreme as -40 to 85 degrees Celsius. The Allen Bradley 1734-OW2 relay output module is thus a reliable option for various industrial automation applications.
