Product Description:
The model SS7B‑481MDOR is a scanning radio receiver operating from 115 VAC at 50 – 60 Hz drawing about 1 A. It automatically scans pre set frequency bands. It captures radio transmissions and converts them into usable signals. The unit is compact, power efficient and suited for continuous industrial operation.
The Danaher SS7B‑481MDOR scanning receiver automatically tunes through selected frequency channels until it detects a valid signal, then stops and processes that input. It uses a voltage controlled oscillator and frequency synthesizer under microprocessor control to step through channels efficiently and avoid spurious birdie signals. The receiver includes mixer, intermediate frequency amplifiers, demodulator and squelch circuits. Its digital synthesizer reduces component count and cost while maintaining tuning flexibility. Upon reception, the signal is amplified and filtered before demodulation and audio or data extraction. This scanning receiver monitor wireless devices like safety light curtains, measurement transmitters or remote sensors. It provide an alert when communication is detected or lost. The model uses include monitoring public safety bands, industrial telemetry links and machine control radio channels. It supports both AM and FM reception with squelch circuitry to suppress unwanted noise. This model automatically locks on detected transmissions, holding until signal ends. It minimizes false stops from spurious birdie frequencies. This scanning receiver provides clean output for integration with automation controllers or safety systems.
The SS7B‑481MDOR scanning receiver integrates with safety systems such as Dolan Jenner SafeScan light curtain systems for machine protection. The scanning receiver balances sensitivity, selectivity and channel search speed. Its compact design draws minimal power while offering robust tuning across VHF/UHF bands. It supports automated equipment by watching remote radio status and triggering control actions when signal thresholds are met.
Frequently Asked Questions about SS7B-481MDOR:
Q: Does the SS7B‑481MDOR support mixed modulation sources across monitored channels?
A: The receiver supports both AM and FM signal types with built-in squelch circuitry. This allows it to monitor varied sources like remote sensors or telemetry links without introducing background noise.
Q: How does the SS7B‑481MDOR avoid locking on spurious birdie signals during frequency scanning?
A: The SS7B‑481MDOR uses a microprocessor-controlled frequency synthesizer and voltage-controlled oscillator to efficiently step through channels. This design minimizes false stops by suppressing interference from birdie signals during automatic scanning.
Q: Can the SS7B‑481MDOR scanning receiver maintain performance in continuous operation for industrial environments?
A: The SS7B‑481MDOR is engineered for nonstop industrial duty with compact size and low power draw from a 115 VAC source. It provides stable signal tracking and reliable audio/data extraction even in demanding settings.
Q: What makes the Danaher SS7B‑481MDOR suitable for integration with machine safety systems?
A: The SS7B‑481MDOR scanning receiver connects easily with systems like Dolan Jenner SafeScan light curtains. It actively monitors wireless channels and triggers automation controls when communication is detected or lost.
Q: How does the SS7B‑481MDOR handle tuning across wide frequency bands without signal loss or performance lag?
A: Its digital synthesizer and intermediate frequency amplifiers ensure precise channel locking and clean transitions. It offers high selectivity while scanning VHF/UHF bands with minimal delay or tuning drift.
