Connection Of Up To Four Switching Outputs - Hydac HDA 5500 Notice D'utilisation

HDA 5500 for HLB 1000 and CS 1000
Example for switching output 1 (relay activated):
Measured variable
hi.1 plus 1% FS
hi.1
On
Lo.1
Lo.1 minus 1% FS
On
Off
Abbreviations: "HI 1" to "HI 4" = High level 1 to 4 = upper switch point 1 or 4
"Lo 1" to "Lo 4"= Low level 1 to 4 = lower switch point 1 or 4
"FS" (Full Scale) = relative to full measuring range

10.3 Connection of up to four switching outputs

Connection example
Depending on the auxiliary voltage and load (especially for inductive loads) the external
circuit must be fitted with a varistor.
