HPE8884BN Network I/O Expansion Unit, BACnet MS/TP 

FW4.02 
 
28 point network point expansion unit for BACnet MS/TP networks. The large I/O count enables remote 
monitoring and control of numerous points at a similar location by one of more master controllers over 
the BACnet network. 
 
Universal inputs may be locally scaled and tagged according to engineering units, calibrated and/or 
filtered to adjust for cabling or sensor characteristics. Digital inputs and UI’s may be configured as pulse 
counters. Digital outputs may have short-cycle timers set. 
 

Typical Applications

 

  Digital/analogue inputs such as alarms, operation statuses, high/low level, water & air flow 

proving, environmental conditions such as temperature, humidity or pressure, and other 
auxiliary contacts. 

  Digital/analogue outputs for switching of fans, pumps, lighting or remote status indication, and 

modulating control of actuators, speed or load controllers and remote analogue gauges. 

  Universal inputs and digital inputs may be used as counting inputs for metering of energy and 

volume and instantaneous load calculation at the Master controller 

 

Feature Summary

 

  8 Digital Inputs (DI n/o or n/c, flip/flop, pulse-counting up to 10Hz) 

  8 Digital Outputs (DO) with power-up presetting & short-cycle timers 

  8 Universal Inputs (UI - user configurable analogue [AI] or digital [DI n/o or n/c], flip/flop, pulse-

counting up to 10Hz) 

  4 Analogue Outputs (AO) with power up presetting 

  RJ11 connected room sensor options (UI1 & UI2 via screw terminals or RJ11 socket) 

  UI’s user definable for non-standard sensors, active or passive from 1kΩ 

  Connected sensors may be calibrated and filtered by way of the UI configuration 

  Isolated, 256 node (1/8

th

 load), RS485 network driver 

  Communication speeds from 2400 baud up to 76800 baud 

  System-wide unique device addressing 

  BACnet application services; Single-Read, Multiple-Read, Single-Write, Who Is, I Am, Who 

Has, I Have 

  BACnet priority array 

  LED indication of the On/Off status of DI and DO points for fast visual status verification 

  Dynamic LED indication of AO status 

  Sequential flashing of DI LED’s as ‘Watchdog’ 

  Automatic communication resumption after a power loss 

  PC configuration by text file download using FUNCPROG or by direct parameter settings entry 

  Upload text file data for retrieving lost application settings, for re-use in other controllers
