Fieldbus power supply

Effective fieldbus power supplies
Single or redundant ISbus series fieldbus power supplies can be used to power fieldbus segments. A high output power, integrated physical layer diagnostics, galvanic isolation and a switchable terminator are features that combine to produce an effective fieldbus power supply for any installation.

Single or redundant 9412 series fieldbus power supplies can be used to power FOUNDATION™ Fieldbus H1 and PROFIBUS PA segments. Their high output of up to 28 V and 500 mA allows large numbers of devices to be operated at farther distances. For high-power applications, two power supplies can supply up to 1 A in parallel boost mode. All models monitor the fieldbus segments to check for overloading and short-circuiting, as well as diagnosing the fieldbus's advanced physical layer parameters, which include jitter and signal level, for example.

To go with the 9412 series fieldbus power supplies, our range includes the 9419 series bus-Carriers. These are also available in versions that are specially tailored for use with automation systems. This guarantees quick, cost-saving installation.

Integrated advanced physical layer diagnostics with signalling contact, adjustable warning level and LED indicator
High output of up to 28 V/1 A for long segments and a high number of field devices
Serial interface for easy-to-read diagnostic data via a smartphone app
