HoW To DemounT 884114

First, remember to demount the connectors with hazardous voltages.

When front leD lights red / display shows ao.er:

884114 is designed as a SIL 2 device with a high safety level. Therefore, a
continuous measurement of the outgoing current is carried out on a 4...20
mA output signal. If the current is 0, an error mode switches on the red front
LED. This function is not a default option but must be actively selected in the
menu. The error mode can only be reset by switching off and then switching
on the supply voltage to the device.

884114
• Input for RTD, TC, Ohm, potentiometer, mA and V
• 2-wire supply > 16 V
• Output for current and voltage
• Universal AC or DC supply

advanced features:

• Programmable by way of detachable display front (884501), process
calibration, signal simulation, password protection, error diagnostics and help
text available in several languages.

application:

• Linearised, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a standard analogue current /
voltage 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 884114 is designed according to strict safety requirements and is thus
suitable for application in SIL 2 installations.

Technical characteristics:

• When 884114 is used in combination with the 884501 display / programming
front, all operational parameters can be modified to suit any application. As
the 884114 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.
