User Manual

UNIVERSAL TRANSMITTER

PReasy 4116

• Input for RTD, TC, Ohm, potentiometer, mA and V

• 2-wire supply > 16 V

• FM-approved for installation in Div. 2

• Output for current, voltage and 2 relays

• Universal AC or DC supply

Advanced features

• Programmable via detachable display front (4501), process calibration, signal

and relay simulation, password protection, error diagnostics and selection of

help text 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 2 pairs of potential-free relay contacts and analogue

output.

• Galvanic separation of analogue signals and measurement of floating signals.

• The 4116 is designed according to strict safety requirements and is thus suit-

able for application in SIL 2 installations.

Technical characteristics

• When 4116 is used in combination with the 4501 display / programming front,

all operational parameters can be modified to suit any application. As the

4116 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. A yellow

LED is ON for each active output relay.

• Continuous check of vital stored data for safety reasons.

• 4-port 2.3 kVAC galvanic isolation.
