Hirschmann (Belden)

Founded in 1924 and based in Neckartenzlingen, Germany, Hirschmann is one of the names engineers write into specifications for industrial Ethernet, and its DIN-rail switches run plant networks in substations, tunnels and process units. Seven Star LLC lists Hirschmann managed switches, a fiber optic repeater and a crane cable reel, and supplies Hirschmann networking devices to integrators and plant teams in Oman as an independent supplier.

Hirschmann switch families listed here

Four managed switch lines appear on this page. The RS20 and RS30 are compact OpenRail switches, shown here as the RS20-1600T1T1 with 16 Fast Ethernet ports and an RS30, the version with two Gigabit ports. The RSP20 belongs to the RSP rail switches, which were introduced with PRP and HSR redundancy for networks that need high availability. The BRS20 belongs to the newer BOBCAT family. The OZD 485 G12-1300 PRO is a repeater that carries RS-485 signals over fiber in line, star or ring layouts. The 154/06 crane boom cable reel assembly is a different kind of product and is not network equipment.

Where Hirschmann equipment is used

Hirschmann industrial switches connect PLCs, drives, protection relays and HMIs in power distribution, oil and gas facilities, water plants, transport systems and factories. Searches such as managed industrial networking and harsh environment network solutions describe the same need: Ethernet that tolerates heat, vibration and electrical noise, with redundancy functions. Many GCC plants standardized on these switches years ago and now need matching units.

Ordering Hirschmann parts: what we need

Hirschmann product codes are long because every position defines hardware. BRS20-12009999, for instance, fixes the port count and types, and further characters set temperature range, supply voltage, approvals and software level. Send the complete code and the order number from the label, plus the firmware version if the unit must join an existing ring. For SFP modules give fiber type and distance. For the cable reel send the crane make, model and the reel part number.

Frequently Asked Questions

How do I read a Hirschmann switch product code?

The code starts with the family, such as RS20, RSP20 or BRS20, followed by digits for the number and type of ports, then characters for uplink media, temperature range, voltage range, approvals and software variant. Hirschmann publishes a key for each family. The label also shows a short order number. Send both so we can confirm the configuration in the manufacturer's documentation.

Can an RS20 or RS30 be replaced by a BOBCAT switch?

The BOBCAT family is the newer generation of compact managed rail switches and covers comparable port counts, but it is a different platform, so do not assume that the configuration file of an RS20 can simply be loaded. Dimensions and terminal layout should be compared too. Send the old product code and we will check which current model the manufacturer names as the successor.

What is the OZD 485 G12 PRO used for?

It is a fiber optic repeater for RS-485 based networks. It converts the electrical bus to optical fiber so that a serial fieldbus segment can span long distances, cross areas with heavy electrical interference or link buildings at different earth potential. State the protocol, baud rate, fiber type and whether a line or redundant ring is planned.

Is Seven Star LLC a distributor of Hirschmann?

No. Seven Star LLC is an independent supplier and is not an authorized distributor or agent of Hirschmann or Belden. We source Hirschmann switches, repeaters and accessories through commercial channels, verify the product code against the manufacturer's documentation, propose the manufacturer's successor when a model is discontinued, and provide the manufacturer's datasheet and declarations with the order, on request.

Which approvals are available on Hirschmann industrial switches?

Approvals are selected in the product code. Depending on the family, Hirschmann offers variants with different certifications; the OZD 485 G12 PRO datasheet, for example, lists cUL 508, Class I Division 2 and ATEX Zone 2. Because two units with the same port layout can differ in approvals, tell us the standard your project requires and we will check the code position that covers it.
