Features

• 9107B Type - Ex HART Transparent Driver. The 9107B is a HART® transparent driver. The device is a 1-channel isolated 1:1 driver barrier for intrinsic safety applications. Operation and drive control of I/P converters, valves and indicators mounted in the hazardous area. The operation of HART® devices is possible as the unit transmits HART® communication signals bi-directionally. HART® transparent driver 1-channel (stock-no. ; 796-7036 796-7036 ) 2-channel (stock-no. ; 827-5362 827-5362 ) 24 Vdc supply via power rail or connectors Fast response time High active output load 725 Ohm / 20 mA Output line fault detection via status relay High galvanic isolation of 2.6 kVac High accuracy better than 0.1% Green and red front LEDs indicate operation status for each channel Output line fault detection The status relay can be ***d as a simple limit switch The PR 4501 displays the process value for each channel and can be ***d to define high and low limits for detection of loop current level Please order the Display Front PR4501 separately (stock-no. ; 796-6890 796-6890 ) SIL2 certified via Full Assessment according to 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.
