Product Details

4131 Type - Universal Trip Amplifier

The 4131 is universal trip amplifier with 1-channel. Programmable via detachable display front (4501), process calibration, relay simulation, password protection, error diagnostics and selection of help text in several languages.

Features and Benefits

Universal trip amplifier
Input for RTD, TC, Ohm, potentiometer, mA and V
2 adjustable alarm limits
When 4131 is used with the 4501 display / programming front, all operational parameters can be modified to suit any application
Please order the Display Front PR4501 separately (stock-no. 796-6890)
Process control with 2 pairs of potential-free relay contacts which can be configured to suit any application
Trip amplifier with window function defined by a high and a low setpoint. The relay changes state outside the window
FM-approved for installation in Div. 2
2 relay outputs
Universal AC or DC supply


The 4131 universal transmitters are programmable via the PR 4501 detachable display module (7966890). The 4501 module allows the programming of the vast array of input and output parameters easily and safely. Together with advanced functions including 2 point calibration, process simulation and diagnostics.
With a simple menu and explanatory text the 4501 is extremely straightforward to navigate. Functions are clearly depicted on the 4 line LCD display even in low light conditions. Line 1 shows the input signal, line 2 shows the units, and line 3 shows analogue output or tag number. Line 4 shows the communication and relay status. In addition the 4501 features password protection. Programming access can be blocked by assigning a password which is conveniently saved in the 4131 transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
