Repeater Power Supply

IsoAmp PWR A 20100

Repeater power supply in a 6 mm housing with calibrated switching of output signals, HART transmission and protective separation.

Repeater power supply for 2-wire transmitters (current loop powered sensors) in an extremely compact 6-mm housing. The A 20100 supplies the transmitter with power and transmits the measurement signal to the output with galvanic isolation and high accuracy.
In case a signal other than the 4 to 20 mA current loop signal is required, the repeater power supply provides various output signals which can be selected via DIP switches. Of course HART signals are transmitted unaltered. The width of just 6 mm also allows use of the repeater power supply in the tightest of spaces.
Facts

• Extremely flat 3-port isolation in a 6 mm modular housing
• Flexible and extremely precise Calibrated switching of output signals
• Quick and easy configuration using lateral DIP switches – easy to access, yet protected against accidental adjustment
• Low-cost assembly Supply of the current loop and galvanic isolation of the measurement signal in one device
• Protective separation up to 300 V according to EN 61140
• SMART transmitter (acc. to HART specification)
• Cross-connection combs for power supply Power supply only wired once for almost any number of parallel repeater power supplies

The active barrier RN221N supplies e.g. a transmitter with power, if required also in the Ex-area, and then transmits the galvanically isolated signal. With the optionally available HART® monitoring the status of the transmitter is monitored. If an error arises a relay at the RN221N sends an alarm. The relay has to be actively set back. Thus even just briefly occurring errors can be easily located.
