1734-IM4

The 1734-IM4 module from Allen Bradley's Point I/O 1734 series serves as a digital AC input interface specifically designed with four individual input points. This unit operates at a nominal voltage of 220 volts AC, making it suitable for applications where such voltage is required. The module's operational characteristics include an on-state voltage range, with the minimum set at 159 volts AC and the maximum at 264 volts AC.

The digital AC input module requires a minimum current of 6.2 mA to engage the on-state condition, while it can handle a maximum off-state current of 2.9 mA. With a nominal input impedance measured at 22.3 kΩ, the 1734-IM4 ensures efficient signal processing.

In terms of input filtering, the unit features a hardware filter with a response time of 20 milliseconds. It also includes a digital input filter that can be configured programmatically to periods between 0 and 65 milliseconds, allowing for tailored performance in various application environments.

The POINTBus current draw for the 1734-IM4 is 75 mA at 5V DC, ensuring it adheres to operational efficiency standards. Additionally, the module limits its power dissipation to a maximum of 0.1 watts, with thermal dissipation reaching up to 3.4 BTU/hr, maintaining low heat generation.

This module is compatible with various terminal bases, including 1734-TB, TBS, TOP, and TOPS, enabling easy integration into existing systems.
