9106B Type - Ex HART Transparent Repeater. PR Electronics 9106B is a HART transparent isolated repeater barrier for intrinsic safety applications. The 9106B signal conditioning repeater supplies 2-wire SMART transmitters and can also be used for 2-wire SMART current sources. HART ; BRAIN protocols are supported and are transferred bi-directionally. Used anywhere intrinsically safe levels of energy need to be sent to devices located in a flammable atmosphere. The 9106B has been designed, developed and certified for use in SIL 3 applications according to the requirements of IEC 61508. Features and Benefits. • 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 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 3 applications • Front LED indicates operation status and malfunction • Can be supplied separately or installed on power rail, PR type 9400 • Fast response time ;5 ms • High accuracy better than 0.1%. • 2-wire transmitter supply >16 V • Output line fault detection • DIN rail mounting • Active and passive mA input • Active or passive output via the same two terminals. Programming. The 9106B universal transmitters are programmable via the PR 4501 detachable display module ( ; 238-0641 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 9106B transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration. What is HART Protocol?. 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.
