NSC Sicherheitstechnik B02842-00 XP95 Three Channel Input/Output Unit

SUPPLY OPTIONS

The XP95 Three Channel Input/Output Unit designed by NSC Sicherheitstechnik is available in the following options:

  in a plastic enclosure
  in a plastic enclosure and with built in bi-directional short-circuit isolator
  as a printed circuit board (PCB)
  as a PCB and with built-in bi-directional shortcircuit isolator

FUNCTION

The XP95 Three Channel Input/Output Unit provides three volt age-free, single pole, change-over relay outputs and three monitored switch inputs.

FEATURES

The XP95 Three Channel Input/Output Unit supervises one or more normally-open switches on each of the three inputs. It is set to return an analogue value of 4 in the event of an open or short-circuit fault and 16 during normal operation. The status of the inputs is reported by means of three input bits.

The change-over contacts of each relay are operated by three command bits.

If the model is ordered with a short-circuit isolator the Input/Output Unit will be unaffected by loop short-circuits on either loop input or output.

ELECTRICAL CONSIDERATIONS

The XP95 Three Channel Input/Output Unit is loop powered and operates at 1728V DC with protocol voltage pulses of 59V.

PROTOCOL COMPATIBILITY

The unit will operate only with control equipment using Apollo XP95 or Discovery protocol. It may also be used to replace earlier Series 90 Three Channel Input/ Output Units.

MECHANICAL CONSTRUCTION

The Input/Output Unit is supplied in an enclosure for surface mounting or as a PCB.

The enclosure is moulded from self-extinguishing, glass-fi lled ABS. Ten 16mm/21mm and six 22mm/38mm dual diameter cable entry knockouts are provided.

Ten LEDs, six red and four yellow, are fi tted to the PCB. All LEDs except the isolator LED can be disabled to conserve loop current.

For each channel, one red LED is illuminated to indicate that the relay is set; a second red LED is illuminated to indicate that the switch input is closed and a yellow LED is illuminated to indicate an open or short-circuit fault.

A separate yellow LED is illuminated whenever the built-in isolator has sensed a short-circuit loop fault.
