Is it possible to use the toroids of old RH84EX relay with Vigirex RH99M range relay. 

Please note that the type E sensors (toroid) in association with the RH84EX are compatible with RH99M , but there is a restriction regarding the threshold which must be more than 300mA by using the TE30 or PE50 toroid.
It is not possible to go under 300mA with the others sensors IE80, ME120, SE200.

In case there is need less than 300mA, you must replace the toroid by A or OA type toroid as available for RH99 relays.
