1734-IB2

The Allen Bradley 1734-IB2 input module provides essential functionality in control and automation systems. It is specifically designed with two sinking DC input channels, allowing for efficient signal monitoring in a compact format. The standard input voltage is set at 24 V DC, while it accommodates a range from 10 to 28.8 V DC, offering flexibility for various applications.

Maximum current consumption at this nominal voltage is capped at 4 mA, making the module suitable for low-power applications. Additionally, the POINTBus current is limited to 75 mA at 5 V DC, supporting efficient data transmission. The isolation voltage guarantees a robust barrier of 50 V for continuous operation, having passed tests at 2500 V DC to ensure reliability.

Power consumption remains efficient at 0.7 W with thermal dissipation measured at 2.4 BTU/hr when operating at elevated voltage levels. The input module’s compatibility with the 1734-TB and 1734-TBS wiring bases simplifies installation procedures. Notably, input impedance is set at a nominal value of 3.6 kΩ, with a maximum of 4.7 kΩ, allowing for optimal signal integrity.

Operating within an environment suited for a temperature range of -20 to 55 °C, the 1734-IB2 also shows resilience against humidity, functioning correctly in conditions ranging from 5 to 95% non-condensing. Status indicators include two yellow LEDs for input states and one LED that toggles between green and red indicating logic status, providing clear feedback during operation.
