P92x/EN FT/H42Page 68/70Technical GuideUser GuideMiCOM P921/P922/P9233. WIRINGMiCOM P92x range of relays have the same terminal layout for common elements.The wiring diagram for each model is provided in Appendix 1 of the TechnicalGuide.3.1 Auxiliary supplyThe auxiliary power supply for the MiCOM P921, P922 & P923 relays can be eitherdirect current with a voltage range of 24-60 VDC, 48-250 VDC,or alternative currentwith a voltage range of 48-250 VAC/ 50-60 Hz. The voltage range (Ua) is specifiedon the adhesive paper label under the top hinged cover on the front of the relay.The auxiliary power supply must be connected only to terminals 33 and 34.3.2 Voltage measurement inputsMiCOM P921, P922 and P923 have 3 phase and 1 earth voltage inputs available.3.3 Logic inputsThe number of logic inputs depends on the relay model. The relays haveprogrammable opto-isolated logic inputs, which can be assigned to any availablelabel or function.Logic inputs for each relay model:Model P921 P922 P923Logic outputs 2 5 5The voltage range of the inputs is identical to the DC (or AC) auxiliary supply rangeof the MiCOM relay (e.g. Uaux = 24-250 Vdc, logic input voltage range = 24-250Vdc).On the same MiCOM P92x relay, the user can mix different voltage levels for thelogic inputs (e.g. Uaux = 24-250 Vdc, Input 1= 48 Vdc, Input 2-5= 110 Vdc).If the user sets the supply of the logic input as AC they are active from 24 to240Vac.The automation functions that can be assigned to these logic inputs can be selectedfrom the AUTOMAT. CTRL Menu.NOTE:3.4 Output relaysDo not forget to select in the CONFIGURATION/ConfigurationInputs Menu weither the voltage input is "AC" or "DC". .The number of logic outputs depends on the relay model. The relays haveconfigurable logic outputs, which can be assigned to any available function.The number of logic outputs available for each relay model is presented in thefollowing table:Model P921 P922 P923Logic outputs 5 8 8The first logic output (RL0) is dedicated to indicate a relay fault (Watchdog, WD) andis not part of this table.The normally closed (NC) contact of the Watchdog (RL0) can not be configured. Theother contacts can be configured to be activated on activation of the differentfunctions available in the relay. A basic output matrix is included in the relay.
