9.7. Digital Inputs and Outputs
PUE HX5.EX-* indicator optionally features 4 digital galvanically isolated inputs
and 4 digital galvanically isolated outputs. Inputs and outputs are fed through
separate cables via cable glands. On inputs and outputs connectors there
is common power and ground for active inputs and/or outputs.
Inputs and outputs cables' insulation is removed at a length of about 150mm,
cable wires are terminated with tubular end sleeves.
It is forbidden to connect electric potential and ground of
internal power supply unit (Uo and GND on IN/OUT interfaces
terminals of the indicator) with an external intrinsically safe
power supply. This would result with loss of intrinsic safety.
Under the threat of loss of intrinsic safety, the user must
connect the supplied cables to the junction box of his/her
electrical system. The connection must be done in
accordance with Ex standard guidelines, and good
engineering practice.
All instruments connected to indicator’s digital IN/OUT
require ‘ia’ or ‘ib’ protection.
Suggested solutions, Ex versions:
GL503.T-C9615,
GL703.T-C9620,
manufactured by Pepperl-Fuchs, or other models of likewise parameters.
