UNIVERSAL TRIP AMPLIFIER
PReasy 4131
• Trip amplifier with input for RTD, TC, Ohm,
potentiometer, mA and V
• 2 adjustable alarm limits
• Programmable via display front
• 2 relay outputs
• Universal AC or DC supply
Application:
• Process control with 2 pairs of potential-free relay contacts which can be con-
figured 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.
• Sophisticated sensor error surveillance, where one relay holds the state imme-
diately 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.
• The 4131 is designed according to strict safety requirements and is thus suit-
able for application in SIL 2 installations.
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 module 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.
• 3-port 2.3 kVAC galvanic isolation.
Mounting / installation:
• Mounted vertically or horizontally on a DIN rail. As the modules can be
mounted without any distance between neighbouring units, up to 42 modules
can be mounted per metre.pr. meter..
