Product Description

• The Siemens LOGO! DM16 24, manufacturer part number 6ED1055-1CB10-0BA2, is a digital input/output expansion module designed for use with compatible Siemens LOGO! 8 programmable logic control systems.
• This module increases the available digital input and output capacity of an existing controller by adding eight digital inputs and eight transistor outputs. It is suitable for industrial automation, machinery control, process equipment, lighting control, electrical panels, and building automation applications.
• The unit operates from a nominal 24V DC power supply with a permissible operating range of 20.4–28.8V DC. Its digital inputs accept compatible 24V DC signals from switches, sensors, and other control devices.
• Eight integrated transistor outputs provide electronically controlled 24V DC switching for compatible external loads. Each output supports up to 0.3A under the manufacturer's specified operating conditions.
• Unlike the relay-output versions of the LOGO! expansion modules, this model uses transistor outputs. The outputs are intended for compatible low-current DC loads and should not be connected in parallel to increase the allowable switching current.
• Electronic short-circuit protection is incorporated into the output circuitry to support the protection of the module and its connected loads.
• The expansion module communicates through the compatible Siemens LOGO! base controller. Its inputs and outputs are addressed through the controller's programmed logic, making it possible to expand an existing automation application without replacing the main controller.
• The LOGO! DM16 24 is an expansion module rather than a standalone programmable logic controller. It requires a compatible Siemens LOGO! base module and the appropriate external power and wiring connections.
• The module features integrated screw-terminal connections for power, digital inputs, and transistor outputs. These connections are designed for installation in industrial control cabinets by qualified personnel.
• Its compact housing measures approximately 71.5mm wide, 90mm high, and 58mm deep. The module installs onto a standard 35mm DIN rail and occupies four standard spacing units.
• The device carries an IP20 protection classification and is intended for installation inside a suitable electrical enclosure. Manufacturer operating-temperature specifications depend on the hardware version, with earlier versions rated from 0°C to +55°C and applicable later versions rated from -20°C to +55°C.
• The Siemens LOGO! DM16 24 provides a practical solution for expanding the number of digital I/O connections in compatible LOGO! automation installations, including control panel upgrades, equipment maintenance, and industrial system expansion.
• Buyers should verify their controller's supported expansion configuration, operating voltage, output current requirements, and applicable installation instructions before connecting the module.
