Q Series Digital input
The Q Series Digital Input Modules are designed to provide reliable and versatile input solutions for industrial automation systems. These modules support a wide range of input voltages, from low DC voltages (like 5-12V) to higher voltages (up to 240V AC), making them suitable for diverse industrial environments. With various point counts, common configurations, and current specifications, they adapt well to different operational needs.
Available in both sink and source types, they offer compatibility with various field devices, depending on current sourcing or sinking requirements. Certain modules are designated as "high speed," ideal for applications that demand rapid response times. By converting physical signals into digital signals that the PLC can process, these digital input modules form a critical component of industrial automation solutions.

Functional Applications
Voltage Ranges: The modules handle a variety of voltage inputs, from low voltage DC (5-12V for sensors) up to higher voltages (up to 240V AC), catering to diverse industrial environments.
Input Type: The differentiation between sink and source type modules allows integration with different types of field equipment, depending on whether they source or sink current.
Speed: Certain modules are denoted as "high speed," which are suitable for applications requiring rapid processing and response times.
Points/Common: This specification shows how many input points share a common electrical point, which is important for wiring and fault isolation.
These input modules are essential components in configuring a PLC system to interface with the real world, converting physical signals (like switch statuses or sensor outputs) into digital signals that the PLC can process, thus forming a critical part of industrial automation solutions.
