PR Electronics 9107B HART transparent driver for operation and drive control of I/P converters, valves and indicators mounted in hazardous areas. Operation of HART devices is possible as the unit transmits HART communication signals bi-directionally. Used anywhere intrinsically safe levels of energy need to be sent to devices located in a flammable atmosphere. The 9107B 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 transmit signals to zone 0, 1, 2 and zone 20, 21, 22 including mining / Class I/II/III, Div. 1, Gr. A-G.
• Configuration and monitoring by way of detachable display front (PR 4501)
• 2.6 kVac galvanic isolation between input, output and supply
• Selection of direct or inverted function for each channel via PR 4501
• Monitoring of internal error events via the individual status relay and/or a collective electronic signal
• Designed, developed and certified for use in SIL 2 applications
• Front LED indicates operation status and malfunction
• Can be supplied separately or installed on power rail, PR type 9400
• Output line fault detection
•DIN rail mounting

The 9107B universal transmitters are programmable via the PR 4501 detachable display module (238-0641). 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 9107B transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.

The HART protocol is a low speed, digital communications scheme that is carried on a 4 to 20 mA current signal. As 4 to 20 mA loops are commonly used in industry, the HART protocol is easy to implement, easy to use, and easy to troubleshoot. Devices that communicate via HART are popular in many industries.
