DM 162 S-DIAS Digital Mix Module SIGMATEK

SIGMATEK DM 162 Digital Mix Module (S-DIAS Digital Mix Module)

SIGMATEK DM 162 is a digital input and output module (Digital Mix Module) in the S-DIAS family for industrial automation control systems, integrating both signal reception and transmission functions into one module. It includes 8 digital inputs and 8 digital outputs.

The input accepts PNP (+24 VDC) signals as specified by the catalog which lists Isolated Digital Input with an Input Delay of 5 ms. The output is also PNP (+24 VDC) for controlling devices that are electrically compatible.

The unit measures 12.5 x 104 x 72 mm (width x height x depth), making it suitable for automation systems requiring digital signal reception and transmission in a single module, though compatibility with the CPU and S-DIAS system must be verified before installation.

Note: The catalog specifies the output current coordinates of DM 162 are inconsistent between the text PNP (+24 VDC 1.7 A) and the maximum current value 0.5 A, so it is necessary to check the specific model datasheet before determining the load output.

Digital Input 8 Channels

DM 162 supports 8 digital input points for receiving status signals from sensors, switches or other devices with output signals conforming to module specifications.

The inputs are PNP (+24 VDC) type which is suitable for connecting devices that supply a positive signal into the input channel when active. However, electrical ratings and wiring diagrams should be checked before connecting wires.

Isolated Digital Input

The catalog specifies that all 8 digital inputs are isolated types but details of circuit isolation such as per-channel or group isolation and insulation voltage test values are not specified.

In circuit design, it is necessary to check the isolation details from the manufacturer's technical documentation to understand signal reference limitations and proper external device connections.

Input Delay 5 ms

DM 162 has an input delay of 5 ms according to catalog information which is data for considering the response time of digital input channels.

When designing the system, consider the signal timing along with Input Delay and CPU processing cycles to ensure proper status reading.

Digital Output 8 Channels

The DM 162 supports 8 digital output points for sending control signals from automation systems to external devices that are compatible.

The outputs are PNP (+24 VDC) type, which is a sourcing output circuit on the positive side (Sourcing Output), used to deliver signals to loads according to commands from the control program.

Before connecting the load, it's necessary to check the operating current, surge current, point ratings per channel, and module total ratings as specified in the datasheet since the values shown in the catalog may not be consistent.

Digital Mix Module for Automation Systems

The integration of Digital Input and Digital Output into a single module allows it to be applied to machines that need to read device status while sending control signals, without having to separate input and output functions into different modules in all cases.

When choosing to use the module, consider the actual number of I/O points needed as well as compatibility with CPU and system S-DIAS components.

Usage with PNP Sensors

The DM 162 supports PNP (+24 VDC) input type for receiving signals from sensors or switching devices that meet the specified signal requirements.

Examples of equipment that can be considered for connection include Proximity Sensor, Photoelectric Sensor, and Limit Switch configured to match the module's input circuitry.

Do not connect NPN sensors instead of PNP sensors without checking the circuit operation and manufacturer recommendations.
