IAMS 0002 / 0022 / 0020
• Input for RTD, TC, Ohm, potentiometer, mA and V
• 2-wire supply > 16 V
• 2 adjustable alarm limits
• FM-approved for installation in Div. 2
• Output for current , voltage and 2 relays
• Universal AC or DC supply
Advanced features
• Programmable by way of detachable display front (PGMMOD 00/C1), process
calibration, signal simulation, password protection, error diagnostics and selec-
tion of 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 2 pairs of potential-free relay contacts and analogue
output.
• Process control with 2 pairs of potential-free relay contacts which can be
configured to suit any application.
• Process control with standard analogue output.
• Galvanic separation of analogue signals and measurement of floating signals.
• The IAMS0002 and IAMS0022 have been designed according to strict safety
requirements and is thus suitable for application in SIL 2 installations.
• Trip amplifier with window function allowing the relay to change state within a
high and a low setpoint on the input span.
• Relay latch function, where the relay is activated and can only be reset
manually.
• Sophisticated sensor error surveillance, where one relay holds the state
immediately prior to the sensor error, thus allowing the process to continue.
The other relay can be set for sensor error alarm so that the defect sensor can
be replaced immediately.
