4114 - Adaptor temperatura

4114 - Adaptor temperatura
Universal transmitter
4114
– Input for RTD, TC, Ohm, potentiometer, mA and V
– 2-wire supply > 16 V
– FM-approved for installation in Div. 2
– Output for current and voltage
– Universal AC or DC supply
Advanced features
• Programmable by way of detachable display front (4501),
process calibration, signal simulation, password protection,
error diagnostics and help text available in several languages.
Connections
Application
• Linearized, electronic temperature measurement with RTD or
TC sensor.
• Conversion of linear resistance variation to a standard analog
current / voltage signal, i.e. from solenoids and butterfly
valves or linear movements with attached potentiometer.
• Power supply and signal isolator for 2-wire transmitters.
• Process control with standard analog output.
• Galvanic separation of analog signals and measurement of
floating signals.
• The 4114 is designed according to strict safety requirements
and is therefore suitable for application in SIL 2 installations.
Technical characteristics
• When 4114 is used with the 4501 display / programming front,
all operational parameters can be modified to suit any
application. As the 4114 is designed with electronic hardware
switches, it is not necessary to open the device for setting of
DIP-switches.
• A green / red front LED indicates normal operation and
malfunction.
• Continuous check of vital stored data for safety reasons.
• 3-port 2.3 kVAC galvanic isolation.
