TO 127 S-DIAS Digital Output Module SIGMATEK

SIGMATEK TO 127 Digital Output Module (S-DIAS Digital Output Module)

SIGMATEK TO 127 is a digital output module (Digital Output Module) in the S-DIAS family for industrial automation control systems, supporting 12 digital outputs with PNP (+24 VDC) output type. It is suitable for controlling electrical devices and loads that are compatible with the module.

The TO 127 module can be applied to machine control and production line systems to operate external equipment such as status lights, interface devices, or control circuits that support PNP outputs.

The catalog specifies a maximum drive current of 1.7 A; however, it is necessary to check the individual channel ratings and total module ratings from the datasheet before selecting electrical loads.

The unit has compact dimensions of 12.5 x 104 x 72 mm (width x height x depth) for installation in SIGMATEK's S-DIAS control system according to mounting requirements.

12 Channel Digital Output (12 Digital Outputs)

The SIGMATEK TO 127 features 12 digital output channels for sending control signals from automation systems to external devices with appropriate electrical ratings.

The presence of multiple outputs allows the design of a system that controls several points within a single module, but it is necessary to check power supply and current limitations per channel before use.

PNP Output Type (+24 VDC)

The TO 127 uses PNP output type which is positive switching (Sourcing Output). According to the circuit design, this outputs positive voltage to the load when active.

Loading connections should be verified according to the power supply terminal, output terminal, and reference point 0 V as per the manufacturer's wiring diagram.

PNP output differs from NPN (Ground Switching) which performs negative switching. Therefore, appropriate end devices and wiring methods must be selected based on the type of output.

Output Current Rating

The SCMA General Catalog Vol.5 specifies the maximum drive current of TO 127 as 1.7 A. However, before using it in a design, further verification is required to determine whether this value refers to per channel current, total current, or under what conditions.

Consideration should be given to operating current, surge current, and the type of load, especially inductive loads such as relays or solenoids, which may require reverse voltage protection according to system requirements.

The value of 1.7 A should not be used as a guarantee for all outputs simultaneously without confirmation from the Datasheet.

Compatibility with S-DIAS System

The TO 127 is an expansion module in SIGMATEK's S-DIAS family designed to extend digital signal channels for compatible automatic control systems.

When selecting it for use with CPUs and other modules, compatibility should be verified, including power supply requirements, connection structure, and installation specifications from the manufacturer’s manual.
