EXL - Large-Scale Plant/Underground Car Park Radio Receiver (4 Channel)

The EXL is used whenever a large number of transmitters are required. 1,000 transmitter keys can be taught in. This makes the EXL ideal for large-scale projects like multi-storey car parks. The 4 potential-free heavy-duty relays in the output provide great versatility. An automatic break-time, which can be switched off prematurely or re-started, can be automatically set for each output. Users (senders) can be “blocked” individually (e.g. rent not paid) or even “deleted”.

  • “ Auto-Off” configurable 1s...17min.
  • Input for “external” button
