Operational Benefits and Performance Characteristics

Discrete Input Specifications and Logic
The module features four discrete inputs configured for sink logic, capable of operating at a typical 125 V DC with surge tolerance up to 156.2 V. This high-voltage capability is advantageous in environments where input signals are generated from heavy-duty machinery or high-power systems. The assured state detection ensures accurate readings, with a clear distinction between low and high states, which is vital for reliable system diagnostics and control.

Output Configuration and Load Handling
Equipped with four solid-state outputs, the 140-DDM-690-00 allows for flexible configuration to meet various industrial needs, supporting both source and sink logic. Each output can handle up to 4 A, with a total module capacity of 16 A, making it ideal for controlling high-power devices such as motors and actuators. The module's ability to manage peak loads of up to 30 A for brief durations further enhances its utility in applications where transient loads are common, such as in robotic systems or conveyor belts.

Protection and Isolation Features

Designed for durability in high-stress environments, the 140-DDM-690-00 incorporates robust protective features. Each input is equipped with resistor-limited protection, while transient voltage suppression safeguards the outputs against voltage spikes. The module also includes a 5 A internal fuse for each output group, providing an additional layer of overcurrent protection. With 1780 Vrms isolation between input and output groups and 2500 Vrms isolation between these groups and the bus,
