UNIVERSAL TRANSMITTER
PReasy 4114
• Input for RTD, TC, Ohm, potentiometer, mA and V
• 2-wire supply > 16 V
• Mounting on DIN rail or wall
• Output for current and voltage
• Universal AC or DC supply

Advanced features:

• Programmable by way of detachable display front (4501), process calibration,
signal simu-lation, password protection, error diagnostics and help text avail-
able in several languages.

Application:

• Linearised, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a standard analogue current / volt-
age signal, i.e. from solenoids and butterfly valves or linear movements with
attached potentio meter.
• Power supply and signal isolator for 2-wire transmitters.
• Process control with standard analogue output.
• Galvanic separation of analogue signals and measurement of floating signals.
• The 4114 is designed according to strict safety requirements and is thus suit-
able for application in SIL 2 installations.

Technical characteristics:

• When 4114 is used in combination 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 module 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.
