Advanced Features; Application; Technical Characteristics - PR 4131 User Manual

• Input for RTD, TC, Ohm, potentiometer, mA and V
• 2 adjustable alarm limits
• FM-approved for installation in Div. 2
• 2 relay outputs
• Universal AC or DC supply

Advanced features

• Programmable via detachable display front (4501), process calibration, relay
simulation, password protection, error diagnostics and selection of help text
in several languages.

Application

• Process control with 2 pairs of potential-free relay contacts which can be
configured to suit any application.
• Trip amplifier with window fonction 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.

Technical characteristics

• When 4131 is used in combination with the 4501 display / programming front,
all operational parameters can be modified to suit any application. As the
4131 is designed with electronic hardware switches, it is not necessary to
open the device for setting of DIP-switches.
• A green 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.
• 3-port 2.3 kVAC galvanic isolation.
