Application
The 3117 is an isolating converter which can be used for signal conversion of standard bipolar analog process signals into a unipolar analog signal.
The unit offers 3-port isolation and provides surge suppression and protects control systems from transients and noise.
The 3117 also eliminates ground loops and can be used for measuring floating signals.
Mounting of the 3117 can be in Safe area or in Zone 2 and Cl. 1 Div 2 area and is approved for marine applications.
Technical characteristics
Flexible 24 VDC (±30%) supply via power rail or connectors.
Excellent conversion accuracy, better than 0.05% of selected range.
Inputs and outputs are floating and galvanically separated.
A green front LED indicates operation status for the device.
All terminals are protected against overvoltage and polarity error.
Meeting the NAMUR NE21 recommendations, the 3117 ensures top measurement performance in harsh EMC environments.
High galvanic isolation of 2.5 kVAC.
Fast input to output response time < 7 ms / > 100 Hz – 10 Hz bandwidth damping possible via DIP-switch.
Excellent signal/noise ratio > 60 dB.
Mounting / installation / programming
Fast and easy configuration of factory calibrated measurement ranges via DIP-switches.
A very low power consumption allows DIN rail mounting without the need for any air gap.
Wide temperature operation range: -25...+70°C.
