Description
Product Overview
The EKS IOL-3000/RX-8D-13-MM-SC is a fiber-optic digital signal receiver from the EKS IOL3000 series, designed to transmit and receive industrial contact and control signals over optical fiber. The module receives optically transmitted digital signals and provides eight electrical digital outputs for connection to PLC, DCS, relay, instrumentation, and other automation equipment. The manufacturer identifies this configuration as a multimode-fiber receiver with SC optical connection and eight digital channels for 12–24 VDC signals.
The EKS IOL-3000/RX-8D-13-MM-SC is particularly useful where conventional copper signal wiring is restricted by long distances, electromagnetic interference, ground-potential differences, or electrically noisy industrial environments. The IOL3000 system converts electrical digital information into optical signals for transmission and then reconstructs the information at the receiving end. This provides galvanic separation between connected control sections while maintaining reliable signal communication.
As part of the EKS IOL3000 family, the EKS IOL-3000/RX-8D-13-MM-SC can be paired with compatible TX modules to create point-to-point or line-based fiber-optic signal links. It is therefore well suited to PLC and DCS remote-I/O extensions, machine control, power-generation equipment, and industrial facilities where dependable digital signal transmission is required over electrically isolated fiber infrastructure.

The EKS product information confirms the eight-channel digital configuration, 12–24 VDC signal range, multimode fiber and SC connector. General IOL3000 documentation specifies 12–30 VDC operating supply and DIN-rail installation; exact values should be confirmed against the installed hardware revision.
Main Features and Advantages
Eight-channel digital signal transmission
The IOL-3000/RX-8D-13-MM-SC provides eight digital signal channels, making it suitable for transmitting multiple discrete control or status signals through a single fiber-optic connection. This can significantly reduce the amount of copper wiring required between separated control cabinets, machines, or plant areas.
Multimode fiber with SC connection
This specific version uses multimode fiber and an SC optical connector. EKS documentation lists multimode 50/125 µm and 62.5/125 µm fiber among the supported IOL3000 configurations, providing a practical solution for industrial installations where fiber infrastructure is already available.
IOL-3000-RX-8D-13-MM-SC
Excellent immunity to electrical interference
Fiber-optic transmission eliminates the conductive path between the two ends of the communication link. This is particularly valuable near high-power motors, variable-frequency drives, generators, welding equipment, transformers, and other sources of electromagnetic interference. Optical isolation also helps address ground-loop and potential-difference problems.
Flexible system architecture
The IOL3000 platform supports point-to-point and line structures, while compatible versions can also be configured for line or ring arrangements. The IOL-3000/RX-8D-13-MM-SC can therefore be integrated into different industrial signal-distribution architectures according to the required topology.
Industrial diagnostics and maintenance
LED status indicators and potential-free fault-relay contacts provide local diagnostic information and can be incorporated into a higher-level PLC or DCS alarm strategy. This helps maintenance personnel identify communication or device faults without relying exclusively on the supervisory system.
Compact DIN-rail installation
The stainless-steel, powder-coated housing and top-hat rail mounting make the module suitable for industrial control cabinets and remote I/O panels. Its modular architecture also makes replacement and service more convenient in long-life automation installations.
Application Fields
The EKS IOL-3000/RX-8D-13-MM-SC is suitable for industrial automation applications where digital control or status signals must be transported over fiber rather than conventional copper wiring. In power-generation plants, it can be used between turbine auxiliary systems, electrical switchgear, generator equipment, remote control cabinets, and centralized PLC/DCS panels where high electrical isolation and noise immunity are required.
In oil & gas, chemical, and petrochemical facilities, the module can provide isolated digital signal transmission between geographically separated equipment areas. Typical signals may include equipment running status, limit-switch feedback, interlock states, valve status, alarms, and other discrete process-control information. Fiber transmission is particularly advantageous in areas with strong electromagnetic interference or significant ground-potential differences.
For metallurgy and heavy manufacturing, the IOL-3000/RX-8D-13-MM-SC can connect remote machinery, production lines, motor-control centers, and PLC cabinets while avoiding long copper signal runs. It is also useful in intelligent manufacturing systems where distributed equipment needs reliable discrete signal exchange without introducing additional conductive communication paths.
The module can further support transportation, infrastructure, building automation, test equipment, and industrial machine applications. When paired with a compatible IOL3000 transmitter, it provides an effective optical extension for PLC and DCS digital I/O, allowing remote signals to be transferred across electrically challenging environments while preserving straightforward electrical interfaces at the control-system side.
