Technical Overview
The Brüel & Kjær Vibro VC-1100-C11 is a compact, 2-channel machinery protection unit from the VIBROCONTROL 1100 series, designed for standalone or small-scale continuous vibration monitoring on rotating equipment where a full VC-6000 rack-based system is not required. According to Brüel & Kjær Vibro’s official ordering documentation, the VIBROCONTROL 1100 part-number suffix fully decodes as follows: variants ending in C01 and C02 include integrated bearing-condition monitoring, at 230VAC and 24VDC power input respectively, while variants ending in C11 and C12 — including this VC-1100-C11 — provide the same core 2-channel vibration protection functionality without the bearing-condition monitoring feature, with C11 specifying 230VAC power input and C12 specifying 24VDC power input. This means the VC-1100-C11 is the standard-power, non-bearing-condition-monitoring configuration of the VC-1100 family.
The confirmed physical and electrical specifications for the VC-1100 series are: an enclosure measuring 360 × 160 × 91 mm, weighing approximately 5 kg, housed in an aluminum enclosure rated IP65 for protection against dust and water ingress, suitable for direct mounting in harsh industrial environments without an additional protective cabinet. The unit operates across an ambient temperature range of 0°C to +50°C. Output-wise, the VC-1100-C11 provides 3 independent alarm relays plus 1 dedicated OK/healthy relay, 2 analog outputs for interfacing with a DCS or PLC, and 2 buffered outputs for connecting portable diagnostic or data-collection instruments without disturbing the protection signal path. The unit is designed to comply with EN 61326-1 (EMC requirements for electrical equipment), EN 61010-1 (safety requirements for measurement equipment), and DIN EN ISO 13849-1 (safety of machinery — safety-related parts of control systems), with a manufacturer-stated mean time to failure (MTTF) of between 640,000 and 696,000 hours — reflecting a design intended for long-term, low-maintenance continuous duty.

Applications
The VC-1100 series is used for compact, dedicated protection of individual critical machines — pumps, fans, small compressors, motors, and gearboxes — where full rack-based monitoring infrastructure is not justified but reliable overspeed and vibration trip protection is still required for safety and asset-protection purposes. Its IP65-rated aluminum enclosure allows it to be mounted close to the monitored machine rather than in a separate control room, simplifying cabling for smaller installations.
Why Seven Star LLC
Seven Star LLC notes that Brüel & Kjær Vibro’s current product roadmap has introduced the VC-1850 and VC-1860 as well as the VC-6000 Compact Monitor as successor platforms to the VIBROCONTROL 1100 series; customers planning a new installation may wish to discuss whether the legacy VC-1100-C11 or a current-generation successor better fits their long-term support and spare-parts strategy. Seven Star LLC’s technical team can advise on this choice based on the customer’s existing infrastructure and provide genuine hardware and full documentation either way, across Oman and the GCC.

Ordering Notes
When ordering, please confirm the required power input (230VAC for the C11 variant, or 24VDC for the C12 variant) and whether integrated bearing-condition monitoring is needed for your application, since that determines whether the C11/C12 or C01/C02 configuration is the correct choice. Seven Star LLC can also provide guidance on migrating to a current-generation VC-1850, VC-1860, or VC-6000 Compact Monitor platform if long-term supportability is a priority for your maintenance planning.
