HBC-radiomatic spectrum EEx FSE 727 Radiobus Receiver Kit

HBC-radiomatic spectrum EEx Remote Control and FSE 727 radiobus® Receiver Kit

The HBC-radiomatic FSE 727 radiobus® receiver paired with the spectrum EEx belly-box transmitter forms a complete, high-integrity wireless control package engineered for hazardous zones, offshore rigs, and heavy marine deck machinery. Built in Germany, this system bridges intrinsically safe operator command inputs in Zone 1/21/22 hazardous atmospheres with modular, serial-bus or relay-switched machine actuation.

The spectrum EEx transmitter utilizes a conductive, antistatic plastic housing and intrinsically safe battery architecture (FuB 06 EEx) to eliminate ignition sources. On the receiving end, the HBC-radiomatic FSE 727 radiobus® unit processes incoming RF packets across dual modular flexcard slots, outputting deterministic proportional analog signals, high-current relay switching, or direct fieldbus telegrams via a heavy-duty Harting HAN 32A industrial multipole interface.

Frequently Asked Questions

What is the difference between the HBC-radiomatic spectrum EEx transmitter and the FSE 727 radiobus receiver?

The spectrum EEx is the portable, intrinsically safe belly-box operator transmitter certified for direct use inside explosive gas or dust atmospheres. The FSE 727 radiobus® is the machine-mounted receiver unit that decodes the radio signals and converts them into up to 26 relay commands, 10 proportional analog outputs, or serial fieldbus signals (such as CANopen, Profibus, or SAE J1939) via a 32-pin Harting HAN 32A connector.

Can the FSE 727 radiobus receiver be mounted directly in an ATEX Zone 1 hazardous area?

The standard FSE 727 radiobus® receiver is approved for direct installation in Ex Zone 2. For deployment inside Ex Zone 1, Zone 21, or Zone 22 hazardous areas on offshore platforms or chemical tankers, the receiver must be housed inside a certified pressure-resistant (Ex d) flameproof enclosure.

What battery and charger are compatible with the HBC-radiomatic spectrum EEx transmitter?

The spectrum EEx operates exclusively on the intrinsically safe FuB 06 EEx 7.2 V DC rechargeable NiMH battery pack, which provides approximately 9 hours of continuous operation. These batteries must only be charged outside the hazardous zone using the dedicated FLG 110B EEx single-slot charger (230 V AC).

How do I verify if a replacement FSE 727 receiver matches my existing crane or hydraulic system?

Check the silver identification nameplate on your existing receiver for the exact RX-FB firmware code, operating frequency band (for example, 433.1–434.75 MHz or 416.8–419.975 MHz), and input voltage range (10–30 V DC or 18–30 V DC). Because the FSE 727 uses modular internal flexcards, matching the housing part numbers (005-01-00554 or 005-01-00613) alone is not enough—the internal bus/relay card configuration must also match your machine’s wiring schematic.

What safety rating does the HBC-radiomatic FSE 727 radiobus system meet for emergency stops?

The emergency stop (E-STOP) circuit on the FSE 727 radiobus® achieves Performance Level d (PL d), Category 3 compliance in accordance with EN ISO 13849-1, utilizing dual redundant safety relays (Si1 and Si2) to safely de-energize crane and hydraulic functions upon E-STOP activation or signal loss.
