140DDI85300C

The 140DDI85300C unit by Schneider Electric forms part of the Modicon series as a discrete input module and is built in a standard format. It possesses 32 discrete inputs that are capable of accommodating various applications, with a positive (sink) logic input type for effective signal detection. The module supports a switching frequency of no more than 100 Hz, optimizing performance in typical operational settings.

This system includes four channels, enhancing its capability to monitor multiple signals simultaneously. It is designed for an input voltage range from 10 to 60 volts, catering to diverse control needs. Additionally, the module ensures robust isolation, rated at 2500 Vrms from group to bus and 700 Vrms for group to group, ensuring protection against electrical interference.

For addressing, the system utilizes a mechanism that employs two input words, allowing for streamlined configuration and signal processing. The weight of this module is 0.295 kg, making it manageable for installation.

The voltage state options for state 1 include ranges of 11 to 24 volts, 34 to 48 volts, 45 to 60 volts, and 9 to 12 volts, providing versatility in connecting compatible devices. The module's power dissipation is calculated as 1 W plus an additional factor based on active input points, offering efficient operation. It is capable of withstanding maximum input voltages of up to 75 volts and requires a bus current of 300 mA during operation.
