BRG TZ Series — Economical Single-Zone Time Zone Clocks in a Compact Plastic Enclosure
By BRG Precision Products | September 15, 2026 | Time Zone Clocks • TZ Series • Economical
BRG’s flagship time zone clocks are engineered for professional installations — aluminum frames, large LED digits, and specifications built for operations centers, military commands, and government facilities. But not every time zone clock installation needs all of that. Sometimes you need a clean, accurate, simple time zone clock for a smaller space, a secondary location, or a budget-conscious application where cost matters.
The BRG TZ Series is built exactly for those situations. Housed in a compact white plastic enclosure just 6.125″ tall with two wall-mounting eyelets on the back, the TZ Series delivers BRG’s legendary accuracy — including OCXO precision to ±1 second over 20 years in the HP models — at a price point that makes per-location deployment practical. Multiple sync options including Ethernet, PoE, Wi-Fi, and DuraTime 2.4 GHz wireless let you integrate TZ Series clocks into any synchronized time system already in use.

Each TZ Series model is available in multiple sync configurations using the prefix code: TZHP (OCXO high precision), TZEN (Ethernet), TZPE (PoE), TZWF (Wi-Fi), or TZRC (DuraTime 2.4 GHz wireless). All models include a 110VAC-to-5VDC power adapter with US plug. Knock-out plugs on the enclosure allow pole mounting in addition to wall hanging.
Sync Options Explained
TZHP (OCXO) — Stand-alone precision. Factory synchronized to the U.S. Atomic Clock. Accurate to ±1 second over 20 years with no network, GPS, or master clock required. Best for locations without network drops or where simplicity is the priority.
TZEN (Ethernet) — Syncs to any NTP server on your network via standard Ethernet connection. Requires a network drop at the clock location.
TZPE (PoE) — Power and NTP synchronization over a single Ethernet cable. No separate power adapter needed when connected to a PoE switch.
TZWF (Wi-Fi) — Syncs to your existing Wi-Fi network and any NTP server. No Ethernet cable needed at the clock location.
TZRC (DuraTime Wireless) — Receives time sync from a BRG DuraTime 2.4 GHz master clock. Integrates into any existing DuraTime wireless system.
