Digital Input Pulse Accumulation - Honeywell Experion 8 Series Technical Information

Series 8 Controller and I/O Specification, S803-150-500
3.3.9.

Digital Input Pulse Accumulation

Function
The Digital Input Pulse Accumulation accepts 24VDC signals as discrete inputs. The first 16 channels can be
configured either as Digital Input or Pulse accumulation to support Pulse Accumulation and frequency measurement
on per channel basis.
Notable Features

Extensive internal diagnostics for data integrity

Optional redundancy

Internal / External field power selection

Galvanic isolation
