KW932

32 Channel Digital to NMEA Interface

With 32 digital inputs the KW932 is designed for interfacing the wide range of alarms such as fire, engine control and other mandatory warnings and equipment status indicators which are required to be connected to the VDR. s to inputs to , Fire Doors, Watertight Doors, etc., , On/Off status switches and indications. Typically these systems have a switch, indicator panel and a junction box where an on/off voltage may be intercepted. The KW932 is capable of accepting from SVDC to ZZOVAC as well as dry contacts.

Advantages

  • Highly flexible interface with wide selection of inputs
  • Data pass through feature supports daisy-chaining for complex installations
  • LED indicators on all inputs/outputs for performance monitoring
  • Certified to IEC60945

32 Channel Digital to NMEA Interface

 

POWER  

Nominal 24v DC at 0.04 Amps. (18 to 32 volts)

INPUT  

8 groups of 4 opto isolated channels. Each group of 4 has its own common line. Voltage input high level 2 to 240 volts DC or AC. Input loading 4 to 10 mA. Voltage input must go to near zero (<5%) in the low state for reliable switching. Can supply its own 24v output for use with isolated contacts such as micro-switches and dry contacts. Series resistors are fitted to each input at installation time to suit the I/P voltage.

OUTPUT  

NMEA 0183 and IEC 61162 $IIXDR for 1 to 8 sentences corresponding to the 8 groups of 4 inputs or Proprietary compact sentence example $PAMI, XDR, A, 0101, 0000, 0000, 1010,*HH cr lf 32 selectable identifiers to allow for multiple interfaces. (Interface “A” in example above) Dip-switch selectable for the number of groups in the data output. Sampling rate 1 per second. Output rate 10 seconds & 1 second when input changes.

DIMENSIONS  

175 x 275 x 70mm
