Loop-powered isolator回路供电隔离器

Type series A47

Features 1-, 2- und 4-channel versi*** Compact housing for snap-on rail mounting - 1 and 2 channels: 12.5 mm width - 4 channels: 22.5 mm width Convenient plug-in terminals Galvanic isolation across input and output No power supply required High accuracy Maximum reliability

Applicati***

The Loop-Powered Isolator separates 0(4)…20 mA standard signal. The task is to ensure reliable and safe plant operation through galvanical isolation between sensor and controller (such as PCS or SPC).The innovation is the new A 47 Advanced Series of Loop-Powered Isolators. An extremely high packing density of 177 channels per meter top-hat rail and outstanding characteristics such as protective separation defy all competition!

Power supply / isolator电源供应器/隔离器

with auxiliary power supply, Type series WG20

Features Compact housing for snap-on rail mounting (22.5 mm wide) Universal galvanic isolation Electromagnetic Compatibility (EMC) Input 2-wire circuitry Output signals 0…20 mA or 4…20 mA, selectable Power supply 24 V AC/DC High accuracy Explosion protection: II(1)G [EEx ib (ia)] II C

Applicati***

The WG 20 power supply/isolator feeds intrinsically safe 2-wire tran***itters. It powers the tran***itter and delivers the measured signal at high accuracy to the output. The WG 20 provides safe separation and high insulation from input to output and to power supply. Thanks to an additional current input it can be used as high-precision standard signal isolator for hazardous circuits. High supply voltage, f***orable hazardous area specificati*** and the easy output signal selection allow for universal applicati***. New vacuum encapsulation technology offers optimum reliability, long-term stability and disruptive strength even under extreme ambient conditi***.

LED on-site indicationLED的现场指示

programmable, Type series PH1520

Features LED on-site indication suitable for stainless steel field housing Ø 60 mm Display: LED with 7-segments, 8 mm high Input: 4…20 mA, current loop Display range: -999…9999, freely adjustable With 3 keys programmable Minimum/Maximum memory Digit (°C / °F, bar, mbar, . . .) Encapsulated electronics

Applicati***

The LED on-site indication is for use in the whole range of measurement technics where the standard signal of 4..20 mA is ***ailable. The display can be adjusted continuously, ensuring good readability of the 7-segment LED display from any viewing angle. The 3-button control panel makes it easy to assign display parameters.

Contact protection relay触点保护继电器

for touch contacts, Type series PG1110, PG1210, PG1310

Features Compact housing for snap-on rail mounting DC voltage output 24 V / 20 mA Pulse control of the contacts 3 designs Supply: 230 V AC

Applicati***

Contact protection relays increase the switching safety and the switching performance of electromechanical limit value switches and reduce the contact load of same. The service life of the contact is c***iderably increased because in the range of 99%, these open and close under tension free conditi*** owing to a pulse and pause ratio of 1 : 100. Fluttering is almost excluded due to a release delay of approx. 0.5s. Contact protection relays are ***ailable for single and double contacts as well as for double contacts in an interval circuit. The relay output switches as a potential-free changeover contact (one per channel). It can be used, for example, for actuating control devices.
