140DDI67300

The Schneider Electric 140DDI67300 discrete input module is engineered for monitoring and control applications. It supports 24 discrete input channels and operates at a nominal input voltage of 125 V DC. The module can handle input voltage levels ranging from 88 to 150 V DC, ensuring compatibility in various setups. A crucial aspect of this module is its capability to manage a maximum absolute input voltage of 156.25 V DC, which includes ripple allowances.

Each input channel operates with a current of 2.5 mA, allowing for precise monitoring of binary signals. It features a positive logic input configuration. The response time for transitions between states is notably quick at 0.7 milliseconds, contributing to efficient signal processing. The 140DDI67300 employs effective isolation techniques, providing 2500 Vrms DC isolation between the group and bus for one minute, ensuring minimal disturbance during operation. For isolation between groups, it offers a rating of 700 Vrms DC for one minute.

Power consumption is calculated at 1 watt plus an additional 0.62 watts multiplied by the number of active channels. The bus current requirement stands at 200 mA. Environmental tolerances are designed with operational temperatures ranging from 0°C to 60°C and storage conditions between -40°C and 85°C. It also maintains functionality in environments with relative humidity up to 95% (non-condensing), making it suitable for various industrial conditions.
