Details

Applications

  • 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.
  • 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.

Features

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


PR 4501 Display / programming front

Application:

  • Communications interface for modification of operational parameters in 4131.
  • Can be moved from one 4131 module to another and download the configuration of the first converter to subsequent converters.
  • Fixed display for readout of process data and status

Technical characteristics:

  • LCD display with 4 lines; line 1 (H = 5.57 mm) shows input signal, line 2 (H = 3.33 mm) shows units. Line 3 alternates between digital output value and scaling (kHz, Hz, mHz, P/m, P/h, P/d) or shows TAG no. Line 4 shows tendency readout for the input signal and communication status.
  • Programming access can be blocked by assigning a password. The password is saved in the converter in order to ensure a high degree of protection against unauthorised modifications to the configuration.

If required, Omni Instruments will program a 4131 to your specific requirements. Please contact us for details.
