RM-DEC-88

and

RM-DEC-88 Opto

16-fold feedback modules (100% compatible with the s88)

from our Digital-Professional-Series !

RM-DEC-88 Opto and RM-DEC-88 for MEMORY,  INTERFACE and Intellibox / TWIN-CENTER with 75cm connection cable.

• For connection to: INTERFACE (up to 31modules), MEMORY (up to 3 modules),  Intellibox / TWIN-CENTER (up to 31modules) and our High Speed Interface HSI-88 (up to 31 modules).

• The feedback modules RM-DEC-88 and RM-DEC-88 Opto can be combined with the s88 feedback modules from Märklin and other manufacturers as required.

• Simple and secure connection of switch rails, contact rails, occupancy sensors or reed-contacts by screw clips.

• The RM-DEC-88 Opto is equipped with additional opto coupler and therefore extremely protected against interference.

• Available as tested and ready to use finished module as finished module in a case or as kit on a 86*76mm pc-board with 4 bores for mounting purposes.(Suitable installation material can be ordered under accessories).

• Our feedback modules RM-DEC-88 and RM-DEC-88 Opto from our Digital-Professional-Series can be operated without any difficulty from your digitally controlled model railroad as these decoders are 100% compatible with the feedback module s88.

• The finished module and the finished module in a case comes with a 24 month warranty.

• Each feedback module will be supplied with a detailed operating- /assembly-instruction.

• From the table below you can see which feedback module may be used with the contacts of your model railroad:

  Kind of contacts	RM-DEC-88	RM-DEC-88 Opto
  Circuit-track (3-conductor rail system)	X	X
  Contact-track (3-conductor rail system)	X	X
  Reed-contact, Occupancy detector with relay output (2-conductor and 3-conductor rail system)	X	X
  Track contact-switch (2-conductor rail system)		X
  Connection cable between contacts and feedback module more than 2 meters (2-conductor and 3-conductor rail system)		X
  Occupancy detector on a 2-conductor rail system (with additional module - see description below) Better to use our octal feedback module with integrated occupancy detection (RM-GB-8).		X
  Turnout-feedback (with additional module- see description below)		X

• Track occupancy detection at two-rail 2-conductor systems: Contrary to the Märklin 3-conductor rail-system can the occupancy of direct-current rails only be reliably realized with electronic circuitry which measure the current at the track section. For this application is it recommended to use our 8-fold feedback module with integrated track occupancy monitor (RM-GB-8). In case you integrated already some occupancy circuits you can combine those with our feedback modules RM-DEC-88-Opto provided that the occupancy circuits have no potential-free outputs. Four of such modules can be connected directly to a feedback module RM-DEC-88-Opto and report the occupancy situation of 16 track sections to the control unit. If the occupancy monitor has potential-free report outputs (e.g. relay contacts) you can apply our feedback module RM-DEC-88.                 

• Feedback from turnouts: If you require the feedback of the actual turnout position to the control unit (or personal computer) you can apply our feedback module RM-DEC-88-Opto. For further information please attend to our description under turnout_ feedback.zip (size: 173KB).

• Extended connection cable:  All LDT feedback modules will be supplied ex factory together with a 75 cm interference protected, twisted s88-bus cable. Additionally we offer extension cables at low cost: Under the order code Kabel s88 0,5m and Kabel s88 2m are at 0,5 respectively 2 meter length interference protected, twisted extension cables available for only € 5,50 respectively € 9,50 .
