20 Digital Inputs (20 Digital Inputs)

The SIGMATEK DI 205 supports receiving signals from 20 digital inputs for connecting status signal sending devices in an automatic control system, allowing data collection from multiple points into a compatible control system.

Examples of equipment that can be considered for use include Proximity Sensors, Photoelectric Sensors, Limit Switches and switching devices with output conforming to the PNP module specifications.

The connection of each type of device must check voltage levels, current and wiring according to the manufacturer's manual.

PNP (+24 VDC) Signal Type

The DI 205 uses a PNP (+24 VDC) input type which generally involves receiving signals from devices that supply positive voltage to the input channel when active.

When used with PNP sensors, wiring must be checked according to the module's Wiring Diagram for power supply point, 0V reference and signal terminal correctly.

Do not connect NPN (Ground Switching) output sensors without checking circuit compatibility as their signal operation modes differ.

Input Delay 5 ms

The SIGMATEK DI 205 has an Input Delay of 5 ms according to the catalog, which is a key feature in considering digital signal response system performance.

In design, consider the Input Delay together with signal pulse width and CPU processing cycle for appropriate status reading by the system.

For high-speed pulse work or signal counting, an Encoder should select a module that specifies Counter capability or High-Speed Input specifically, as the catalog does not specify such functions for DI 205.

Compatibility with S-DIAS System

DI 205 is an S-DIAS family module to expand digital signal inputs of compatible control systems. The CPU, power supply, and other modules must be selected according to system requirements.

The actual number of connected modules depends on the capabilities of the CPU and power supply system, as well as engineering limitations outlined in the manufacturer's manual.

Physical Dimensions (Mechanical Dimensions)

Comparison between DI 204 and DI 205

Specifications	DI 204	DI 205
Digital Inputs	20	20
Input Signal	NPN (Ground Switching)	PNP (+24 VDC)
Input Delay	5 ms	5 ms
Dimensions	12.5 x 104 x 72 mm	12.5 x 104 x 72 mm

Choosing between DI 204 or DI 205 should primarily consider the type of sensor signal, with DI 205 suitable for PNP (+24 VDC) signals and DI 204 supporting NPN (Ground Switching).

SIGMATEK DI 205 Selection Guidelines

• Check the number of Digital Input points required.
• Verify that the sensor signal type is PNP.
• Review voltage and current input ratings from the datasheet.
• Consider the 5 ms Input Delay to suit the nature of the signal.
• Ensure compatibility with CPU and S-DIAS system.
• Check power supply systems for both module and sensor.
• Evaluate installation space and wiring requirements.
• Review pinout diagram before installation.

Installation Precautions

• Verify PNP signal type before connecting input.
