Product Short Description
Product Overview
Distributed digital input expansion module supporting Eaton XC100/XC200 series PLC control systems, collecting 16 channels of 24 V DC discrete switch signals from field sensors, limit switches and safety contactors. It realizes remote signal collection via XIOC bus to reduce cabinet wiring length and on-site construction cost.

Working Principle
Field 24 V DC switch signals pass through optocoupler isolation circuits of each channel, converting on-off electrical signals into digital logic levels recognizable by the module’s communication chip. The module packages all 16-channel signal status data into XIOC bus protocol frames and transmits them to the main XC PLC controller in real time. Built-in RC filter circuit delays signal identification for 0.5 ms to filter jitter signals generated by mechanical switch bounce. If reverse voltage or overvoltage occurs at the input terminal, the channel protection circuit automatically cuts off the signal path to avoid damage to internal chips.
Structural & Material Characteristics
- Shell: Self-extinguishing PA66 plastic industrial housing, flame retardant UL94 V0 grade
- Mounting base: Integrated DIN rail buckle, detachable for easy disassembly
- Wiring terminals: Spring push-in terminals supporting 0.34–1.5 mm² flexible cables
Installation Requirements
- Fixed on standard 35 mm top-hat DIN rail inside PLC control cabinet
- Install XIOC communication bus cable between module and PLC CPU without crossing AC power cables
- Maintain minimum 10 mm vertical gap between adjacent I/O modules for heat dissipation
Application Scenarios
Automotive assembly line sensor signal collection, packaging machinery limit switch monitoring, water pump station equipment running feedback signal input, warehouse conveyor safety switch acquisition, food processing machine protection signal collection.
Operation & Maintenance Precautions
- Do not input AC voltage into digital channels; overvoltage will burn optocoupler isolation components
- When wiring field proximity switches, strictly distinguish NPN/PNP signal types to avoid no signal recognition
- Regularly check spring terminal tightness every half year to prevent signal loss caused by loose wires
