•Trip amplifier with window function defined by
a high and a low setpoint. The relay changes
state outside the window.
•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 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
module 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.

Application:
Technical characteristics:
• Communications interface for modification of operational parameters in 4131.
• LCD display with 4 lines; Line 1 (H=5.57 mm) shows input
signal, line 2 (H=3.33 mm) shows units, line 3 (H=3.33 mm)
shows TAG no. and line 4 shows communication and relay
status.
• Can be moved from one 4131 module to
another and download
the configuration of the first trans­mitter to
subsequent transmitters.
• Fixed display for visualisation of process
data and status.
• Programming access can be blocked by assigning a password. The password is saved in the transmitter in order to
ensure a high degree of protection against unauthorised modifications to the configuration.
Mounting / installation:
• Click 4501 onto the front of 4131.
