Pathway eDIN Contact Closure interface provides twelve DMX-controlled dry contact closures for both power and signal level switching.

1003 Contact Closure

The eDIN #1003 provides DMX512 control over twelve form-C relays, for signal level switching, in a DIN-rail mountable format.  Each relay may be independently wired for normally-open (NO) or normally closed (NC) operation.  Field configurable through front panel or by RDM, the #1003 has nine operating modes for maximum flexibility of use.

  • DMX512 start address and operating mode may be set from front panel interface or remotely using E1.20 RDM
  • DMX512-present relay (normally open or normally closed)
  • Indicator LEDs for power, processor, DMX input, and relay status
  •  Pluggable terminal block connections accept solid or stranded wire between #26 and #16 AWG
  • Normally open or normally closed wiring option for each relay
  • User-adjustable trigger threshold (default to 50%)
  • One DMX512-A/RDM data input connection
  • One passive DMX512-A data through connection
  • Suitable as pilot relay for high voltage contactors, with adequate arc protection (by others)
  • Data and power easily daisy-chained between modules
  • Termination switch
  • User-initiated diagnostics and test modes
  • Firmware field-upgradable using RDM (requires Pathway Pathport gateway and RDM utility program)
  • 12 Channel Maintained
  • 12 Channel Momentary
  • 12 Channel Momentary "ON"
  • 6 Channel Momentary Split
  • 6 Channel Maintained Split
  • 12 Channel Momentary Split with Secondary "Reset"
  • Chase
  • Single Channel Select
  • Single Channel Build
  • Relays rated for minimum 100,000 operations at 2A at 30VDC
  • 1500V opto-isolation between DMX input and module electronics
  • 250V fault protection on DMX input
  • Input operating voltage: 9-30 VDC
  • 6W power consumption
