1 Universal signal transducer with fully isolated inputs and outputs Universal signal transducer Full isolation between the inputs and outputs Signals can be converted and linearised Adjustable signal level and curve rotation All outputs short-circuit proof Use The universal signal transducer is used for galvanic isolation of various current and voltage signals. These can be converted in the signal transducer and linearised. The signal level and curve rotation can also be adjusted. Functions A V supply Signal structure... V... ma... VPhs V ref ext. X X Electrical isolation Y Y... V... ma V ref ext. V Input side Output side The input signal goes into an A/ converter before passing through an opto-isolator to the output stage. The signal is then processed to give the appropriate voltage ratio as determined by the settings for Y (cut-in) and Y (slope), and finally provided as a filtered analogue output. Electrical isolation Electrical protection In addition to the opto-isolation between signal inputs and outputs, each stage has a fully-isolated electrical supply. All inputs are overvoltage-proof to A V and V. Higher voltages will damage the transducer. The outputs are all short-circuit proof (including the auxiliary supply voltage). There is full isolation between the inputs and outputs and the A V supply. Siemens Building Technologies ANE /. Landis & Staefa ivision /

Example : universal signal transducer Technical design Adjustment ranges and characteristic curves Reference inputs/outputs The input or output curve setting is determined by an internal reference of. V or an external reference voltage. For an external reference, Switch or Switch should be set to "external". The external reference voltage is connected to Terminals and (Vref. ext.) or Terminals and (Vref. ext.). Examples: For the internal reference voltage: % =. V For the external reference voltage: e.g. % =. V (see connection example ) Signal adaptation Specific signal levels and curve rotations can be achieved to an accuracy of % by adjusting the associated potentiometers and step switches with a suitably sized screwdriver. The relevant scale is the one associated with the connected input or output. Setting the curves Input signal A separate minimum value (X) and maximum value (X) can be set for the input signal. A coarse setting, in steps of %, can be set on potentiometers and. Potentiometers and are used for a fine, linear, adjustment. Output signal A separate minimum value (Y) and maximum value (Y) can be set for the output signal. A coarse setting, in steps of %, can be set on potentiometers and. Potentiometers and are used for a fine, linear, adjustment.

3 Mechanical design The universal signal transducer consists of a metallic enclosure, accommodating the electronic PB. The facilities for connection and adjustment are located externally for easy access. The connections and adjustment options are as follows: Input side A V V SGN ˆ V ma VPHS SGN ˆ V ma SGN Vref.ext.

The connection terminals should be freely accessible. The air must be allowed to circulate freely, to dissipate the heat generated during operation. Surface mounting The base incorporates four drilled holes for surface mounting. Rail mounting The base of the housing is designed for snap-mounting on standard IN/EN rails. Rail type: EN- x.
