Card Reader Connection

Helios IP (Part Nos. 91371…U) can be equipped with an internal multifunction

module including an RFID card reader (Part No. 9137430E). This module enhances the

Helios IP functions with an EM41XX RFID card reader, two relays for external load

switching, two logical inputs and RS-485 and Wiegand interfaces. The current

Helios IP software version, however, supports the card reader and relays only.

Caution

 The 2N

Helios IP modules ending with U (i.e. 91371…U) can only be

equipped with the card reader.
