Electric isolation between input, outputs and power supply. Prevents false measurement due to spurious potentials.
Processes live zero signals, provision for signal conversion. Green LED signals indicates device in operating condition.
Electrical insulation between power supply versus all other circuits -3.0 kV, and between input and outputs -2.3 kV
Special Features
Accuracy class 0.2 as per International Standard IEC/EN 60 688.
Output Response Time < 250 ms
Fast and easy installation on DIN RAIL or onto a wall or in panel using optional screw hole bracket.
Electric Isolation
1) Two electrically isolated analog outputs prevent interference voltage and current. Solves grounding problem in meshed signal networks.
2) High electric isolation between input and outputs – 2.3 kV, and power supply versus all other circuits – 3.0 kV.
Function
Simple dc isolator serves to electrically isolate input dc signal in the range : 0 – 20 mA
or 4-20 mA or 0-10V or 2-10V is then converted to signal 0 – 20 mA or 4-20 mA or 0-10V or 2-10V
Application
Theta 50 is used to electrically isolate input, outputs and power supply.
The isolator ful lls all requirements and regulation concerning electromagnetic compatibility EMC and safety (IEC61326-1 and IEC 61010-1:2010).
The device has one input and provides two independent outputs in an extremely small space.
