• 2 relay outputs with latching functionality
• 2 adjustable alarm limits
• Universal AC or DC supply
• A green front LED indicates normal operation and malfunction and a yellow LED is ON for each active output relay
• 3-port 2.3 kVAC galvanic isolation
• Trip amplifier with window function defined by a high and a low setpoint
• FM-approved for installation in Div 2
• Complies with NAMUR 21 (burst), NE43 (sensor error), LVD and UL 508
• DIN Rail mounting

The 4131 universal transmitters are programmable via the PR 4510 detachable display module (238-0641). The 4510 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 4510 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 4510 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.
