PR Electronics 9116B universal converter for the conversion and scaling of temperature, voltage, potentiometer and linear resistance signals. Featuring an advanced relay configuration, the 9116B signal conditioner provides relay functionality such as setpoint, window, delay, sensor error indication and power monitoring. The 9116B has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.

• Can be mounted in the safe area or in zone 2 / cl. 1 div. 2 and receive signals from zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I/II/III, Div. 1, Gr. A-G
• Configuration and monitoring by way of detachable display front (PR 4501/4511)
• 2.6 kVac galvanic isolation between input, output and supply
• Active / passive mA output via the same two terminals
• Monitoring of error events and cable breakage via the individual status relay
• Designed, developed and certified for use in SIL 2 applications
• Front LED indicates operation status and malfunction
• DIN rail mounting
• Active and passive mA input
• Active or passive output via the same two terminals

The 9116B 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 9116B transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
