GC 52500

Product catalog summary

Overview: The GC 52500 Repeater Power Supply is designed for supplying and isolating 2- and 3-wire SMART Transmitters and active sensor signals with HART communication. It provides power to the transmitter and transmits the measuring signal with high accuracy and galvanic isolation to the output. It also supports active 0/4 … 20 mA signals from 4-wire transmitters and allows bidirectional HART communication.

Key Features:

Universal operation for 2-, 3-, and 4-wire transmitters.
Bidirectional HART data transfer for repeater and isolator operation.
3-Port isolation to prevent erroneous measurements due to parasitic voltages or ground loops.
Compact design with a 6.2 mm slim housing for easy installation.
Optional In-Rail-Bus connector for fast and economical installation.
Protective separation according to EN61140 to protect personnel and devices from high voltage.
5-year warranty covering defects.

Technical Specifications:

Input: 0/4 … 20 mA signals, input resistance ≤ 50 Ω, overload capacity of 50 mA / 30 V.
Output: 0/4 … 20 mA signals, load capacity 0 … 600 Ω, linear transmission range –1 ... +110%.
General Data: Transmission error < 0.1% full scale, temperature coefficient < 100 ppm/K, response time T99 7 ms, test voltage 3 kV AC.
Environmental Conditions: Operating temperature –25 °C to +70 °C, storage temperature –40 °C to +85 °C.
Power Supply: 24 V DC, voltage range 16.8 V … 31.2 V DC, power consumption approx. 1.3 W.
Construction: 6.2 mm housing, protection class IP 20, DIN rail mounting.

Installation and Connection: The device features captive plus-minus clamp screws, supports a wire cross-section of max. 2.5 mm², and allows optional power connection via In-Rail-Bus.

Catalog excerpts

The Repeater Power Supply GC 52500 is used to supply and separate 2- and 3-wire SMART Transmitters and active sensor signals with HART communication. It supplies the transmitter with power and transmits the measuring signal with high accuracy galvanic isolated to the output. Alternative the measuring input accepts active 0/4 ... 20 mA signals from 4-wire transmitters. In addition to the analog signal, the GC 52500 also transmits data protocols for HART communication with the field device from every point of the cabling. The auxiliary power can be supplied via the connection terminals or via the optional In-Rail-Bus connector. A green LED on the front of the unit has been provided to monitor the power supply. • Universal operation of SMART Transmitters Energization and separation of field located 2-, 3- and 4-wire transmitters • Bidirectional HART transmission HART data transfer for repeater and isolator operation • 3-Port isolation Protection against erroneous measurements due to parasitic voltages or ground loops • Extremely slim design 6.2 mm slim housing for a simple and space saving installation • Optional In-Rail-Bus mounting rail connector allows for fast and economical installation • Protective Separation acc. to EN61140 Protects service personnel and downstream devices against impermissibly high voltage • 5 Years Warranty Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender
