LW213 – LW214 (1300 nm) & LW215 – LW216 (850 nm)
Optical fiber modules for transmission of incremental encoder or sensor signals
Product features:
 Modules for data transmission of incremental encoder or sensor signals via an optical fiber
 Safe and reliably transmission of incremental signals, up to a distance of 3000 meters
 Four channels allowing a signal transmission with a sample rate of 10 MHz each
 For all incremental RS422, 5V-TTL or 10 to 30 V HTL encoders and sensors
 The optical fiber cable can be routed through explosive areas as well
 Input / Output data rate of max. 2 Mbit/s (transmitter and receiver)
 Resistant against extremely strong electromagnetic fields
 Already assembled optical fiber cables are available
 Power supply either 5 VDC or 10 to 30 VDC
Available systems (Transmitter and receiver with the same wave length are arbitrarily combinable):
Transmitter (1300 nm)
LW213
LW213-1
LW213-2
LW213-3
Receiver (1300 nm)
LW214
LW214-1
LW214-2
*) dual channel transmitter variants cannot be operated as single channel units

    1. Safety Instructions and Responsibility 1.1 General Safety Instructions This operation manual is a significant component of the unit and includes important rules and hints about the installation, function and usage. Non-observance can result in damage and/or impairment of the functions to the unit or the machine or even in injury to persons using the equipment! Please read the following instructions carefully before operating the device and observe all safety and warning instructions! Keep the manual for later use.

  • Page 4: Installation

    For placement, wiring, environmental conditions as well as shielding and earthing/grounding of the supply lines the general standards of industrial automation industry and the specific shielding instructions of the manufacturer are valid. Please find all respective hints and rules on www.motrona.com/download.html --> “[General EMC Rules for Wiring, Screening and Earthing]”.

  • Page 5: Description

    2. Description The optical fiber modules LW213/LW214 and LW215/LW216 form together a transmission system for data transmission of industrial signals by means of optical fibers. Both, transmitter and receiver modules, provide four channels which are completely independent of each other, with differential inputs and outputs. All four channels allow the transmission of signals with a maximum data rate of 2 Mbit/s.

  • Page 7: Electrical Connections

    Exceeding the supply voltage of the modules LW213, LW214, LW215 and LW216 above a value of about 6 V provokes destruction of the fuse located inside of the device and must thus be avoided.

  • Page 8: Optical Connections

    3.3. Optical Connections For connection of the modules a cord set of multimode optical fiber cables assembled by motrona can be used. Alternatively any multimode optical fiber cable 50/125 µm or 62.5/125 µm will be suitable. Single-mode optical fiber cables cannot be used.
