PR Electronics 1 Channel Galvanic Barrier, ATEX

PR Electronics 5115A intrinsically safe programmable transmitter for redundancy measurement of temperature by means of two sensors, where the secondary sensor takes over the measurement when a sensor error occurs on the primary sensor. With a wide variety of jumper selectable inputs for current/voltage or temperature and conversion of linear resistance the 5114 transmitters are suitable for a wide range of temperature measurement applications.
The 5115A transmitter can be configured, with or without a power supply, using the PReset software and the Loop Link communications unit (RS stock number 796-7020).
The 5115A signal conditioner is based on a microprocessor core with an efficient program operation. The basic calibration data and present set-up are stored in an EEPROM thereby avoiding the loss or change of data at power off.

• Redundancy measurement with 2 input signals
• Input for RTD, TC, mV, linear resistance, mA and V
• Signal calculator with four arithmetical operations: Addition, subtraction, multiplication and division
• LED indicators for normal operation, sensor error on each sensor, and functional error
• Universal voltage supply
• 3.75 kVac galvanic isolation
• Duplication of the input signal to two separate analogue outputs
• I.S. safety barrier and power supply for 2-wire transmitters
