Revision:0 Date: 11/01/2021 1.0 Device Overview and Description The B034 RF 2.4GHz module has been designed to extend wireless communication in IMET radio control systems in the 2.4GHz to 2.4835GHz band, making 38 channels available in the assigned band. The device is integrated into the logic units of the IMET industrial remote control systems, to allow greater coverage and reliability in the communication between the remote unit (radio control or transmitter unit M880 THOR2; M880 ZEUS2; M880 KRON; M880 ZED; M880 ARES2) and the base station (receiver unit M880 HAC; M880 HDC; M880 LDC; M880 LAC). The B034 module mounts two antennas with U.FL 50 connectors to ensure greater coverage and stability in radio communication. The B034 is assembled by welding and has its own internal voltage regulators one for the RF part and one for the microcontroller logic part and its own oscillators. The module can it be easily integrated (surface mount) with M880 systems, freeing up the design dedicated to the RF communication part and from the compliance tests with the reference standards listed in the section 6.0 Approval and Certification allowing more faster construction times for the new M880 products. The B034 module is approved for modular devices in the United States (FCC) and Canada (IC). Modular approval removes the need for expensive RF and antenna design, and allows the end user to place the B034 module inside a finished product and does not require regulatory testing for an intentional radiator (RF transmitter). To maintain conformance, refer to module settings in Annex A.1 for the United States and Annex A.2 for Canada. The B034 module is an RED Directive assessed radio module for operation in Europe. The module tests can be applied toward final product certification and Declaration of Conformity (DoC). To maintain conformance for Europe, refer to module settings in Section ANNEX A.3. Additional testing may be required depending on the end application. Technical Manual file.dot revisione n 0 data: 24/02/2020 IMET s.r.l. Via Ronche, 93 33077 Sacile (PN) ITALY Tel.
