What is the meaning of “operating voltage” and “Control circuit voltage” for RSL slim interface relays.

There are 4 sockets with "operating voltage" as following: (12/24), (48/60), 110, 230 Vac/dc.
And these sockets control our 4 types of slim-relays with coil voltages as following: 12, 24, 48, 60 Vdc.

Slim-relay 12Vdc is controlled by a socket 12/24Vac/dc RSLZA1
Slim-relay 24Vdc is controlled by a socket 12/24Vac/dc RSLZA1
Slim-relay 48Vdc is controlled by a socket 48/60Vac/dc RSLZA2
Slim-relay 60Vdc is controlled by a socket 48/60Vac/dc RSLZA2 or 110Vac/dc RSLZA3 or 230Vac/dc RSLZA4

The "Operating voltage" indicates the voltage that the user must apply on the input of socket to activate the relay.
The "Control circuit voltage” indicates the voltage which will be applied on the input of slim-relay (in order to indicate to the customer the right voltage rating of relay, if he replaces it).

The sockets adapt the operating voltage to the slim-relay which is limited to 60Vdc. They are all equipped with a PCB including voltage suppressor, Diode Bridge, resistance, and LED.

For example: RSL1PVPU =>The compatible relay is RSL1AB4ND (60V DC) and compatible socket is RSLZVA4. You can apply across it 230 V AC /DC, then the voltage will be conditioned to 60VDC through the PCB and you will have only 60V DC applied across the coil. Refer to attached catalogue page.
