Application Scenarios & Industry Solutions

Building Automation & HVAC Control: Manage multi-zone climate systems with independent temperature sensor inputs and relay-switched damper actuators, fan motors, and heating elements. The module's 230V relay outputs directly control standard HVAC equipment without intermediate relays, reducing component count and improving system reliability in commercial buildings, hotels, and institutional facilities.

Manufacturing Process Control: Coordinate conveyor systems, sorting equipment, and material handling operations with discrete input monitoring of limit switches, proximity sensors, and safety interlocks. Relay outputs drive pneumatic valves, indicator lights, and small motors in packaging lines, assembly stations, and quality control checkpoints.

Water & Wastewater Management: Implement pump control strategies with level sensor inputs and relay-switched pump contactors. The module's robust relay contacts handle inductive loads associated with pump motors, while digital inputs monitor float switches, pressure transducers, and alarm conditions in lift stations, treatment plants, and irrigation systems.

Access Control & Security Systems: Integrate card readers, motion detectors, and door contacts as digital inputs while controlling electromagnetic locks, barrier gates, and alarm sirens through relay outputs. The 230V switching capability supports direct control of access control hardware in parking facilities, warehouses, and restricted areas.

Lighting Management Networks: Deploy intelligent lighting control with occupancy sensor inputs and relay-switched lighting circuits. Each relay output independently controls lighting zones, enabling energy-saving strategies such as daylight harvesting, scheduled operation, and occupancy-based switching in warehouses, parking structures, and commercial spaces.

Technical Parameters & Selection Guide

Selection Criteria: Choose the DM16 230R when your application requires 230V AC relay switching with moderate current capacity (up to 10A per output). For higher current loads, consider external contactors. If your system operates on 24V DC logic, evaluate the DM16 24R variant instead. Verify LOGO! 8 base unit compatibility before ordering—this module does not support LOGO! 7 or earlier generations.

Extended Functions & Integration Capabilities

Frequently Asked Questions

Q: How many DM16 expansion modules can I connect to a single LOGO! 8 controller?
A: You can daisy-chain up to 3 expansion modules per LOGO! 8 base unit, providing a maximum of 24 additional relay outputs and 24 digital inputs when using three DM16 230R modules.

Q: What is the maximum cable length between the LOGO! controller and expansion modules?
A: Expansion modules connect via integrated bus connector with no external cabling required. Modules mount directly adjacent to each other on the DIN rail, ensuring reliable communication without distance limitations.

Q: Can the relay outputs switch DC loads or only AC loads?
A: The DM16 230R relay contacts are rated for both AC and DC switching. For DC loads, observe derating curves in the technical manual—typical DC switching capacity is 5A at 24V DC per contact.

Q: Does this module support high-speed counting or pulse input functions?
A: Digital inputs on the DM16 230R are designed for standard discrete sensing applications. For high-speed counting (>2kHz) or pulse measurement, use dedicated LOGO! analog modules or high-speed counter variants.

Q: Is the module compatible with LOGO! 7 controllers or earlier versions?
A: No, the 6ED1055-1FB10-0BA2 is exclusively compatible with LOGO! 8 series controllers. For LOGO! 7 systems, specify the 0BA0 generation expansion modules.

Q: What type of input sensors can I connect to the digital inputs?
A: The 230V AC digital inputs accept dry contacts, proximity switches, photoelectric sensors, float switches, and any two-wire sensor compatible with 230V AC sensing voltage. Ensure sensors are rated for the input voltage.
