Switch Amplifier, KFA5-SR2-EX1.W
Switch Amplifier, Timer Relay KFA5-SR2-EX1.W 1-channel isolated barrier 115 V AC supply Dry contact or NAMUR inputs Relay contact output Line fault detection (LFD) Reversible mode of operation Up to SIL 2 acc. to IEC 61508/IEC 61511 This isolated barrier is used for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. The proximity sensor or switch controls a form C changeover relay contact for the safe area load. The barrier output changes state when the input signal changes state. The normal output state can be reversed using switch S1. Switch S3 is used to enable or disable line fault detection of the field circuit. During an error condition, relays revert to their de-energized state and LEDs indicate the fault according to NAMUR NE44. .tg {border-collapse:collapse;border-color:#9ABAD9;border-spacing:0;} .tg td{background-color:#EBF5FF;border-color:#9ABAD9;border-style:solid;border-width:1px;color:#444; font-family:Arial, sans-serif;font-size:14px;overflow:hidden;padding:10px 5px;word-break:normal;} .tg th{background-color:#409cff;border-color:#9ABAD9;border-style:solid;border-width:1px;color:#fff; font-family:Arial, sans-serif;font-size:14px;font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;} .tg .tg-8wjn{background-color:#409cff;border-color:inherit;color:#efefef;font-size:18px;font-weight:bold;text-align:left; vertical-align:middle} .tg .tg-kivi{background-color:#ebf5ff;border-color:inherit;font-weight:bold;text-align:left;vertical-align:top} .tg .tg-get6{background-color:#409cff;border-color:inherit;color:#FFF;font-size:18px;font-weight:bold;text-align:left; vertical-align:middle} .tg .tg-jnh8{background-color:#ebf5ff;border-color:inherit;color:#425563;text-align:left;vertical-align:top} .tg .tg-v47f{background-color:#409cff;color:#ffffff;font-size:18px;font-weight:bold;text-align:left;vertical-align:top} .tg .tg-h1e6{background-color:#ebf5ff;border-color:inherit;color:#425563;text-align:center;vertical-align:top} .tg .tg-lvgc{background-color:#ebf5ff;border-color:inherit;color:#425563;text-align:left;vertical-align:middle} .tg .tg-iq83{background-color:#409cff;border-color:inherit;color:#efefef;font-size:18px;font-weight:bold;text-align:left; vertical-align:top} .tg .tg-sa29{background-color:#ebf5ff;border-color:inherit;text-align:center;vertical-align:top} .tg .tg-riw3{background-color:#ebf5ff;border-color:inherit;text-align:left;vertical-align:top} .tg .tg-wqna{background-color:#409cff;border-color:inherit;color:#ffffff;font-size:18px;font-weight:bold;text-align:left; vertical-align:top} .tg .tg-0lax{text-align:left;vertical-align:top} General specifications Signal type Digital Input Functional safety related parameters Safety Integrity Level (SIL) SIL 2 Supply Connection terminals 14, 15 Rated voltage 103.5 ... 126 V AC , 45 ... 65 Hz Power consumption 1 W Input Connection side field side Connection terminals 1+, 2+, 3- Rated values acc. to EN 60947-5-6 (NAMUR) Open circuit voltage/short-circuit current approx. 8 V DC / approx. 8 mA Switching point/switching hysteresis 1.2 ... 2.1 mA / approx. 0.2 mA Line fault detection breakage I ≤ 0.1 mA , short-circuit I > 6 mA Pulse/Pause ratio min. 20 ms / min. 20 ms Output Connection side control side Connection terminals 7, 8, 9 Output signal, relay Contact loading 253 V AC/2 A/cos φ > 0.7; 126.5 V AC/4 A/cos φ > 0.7; 40 V DC/2 A resistive load Energized/De-energized delay approx. 20 ms / approx. 20 ms Mechanical life 107 switching cycles Transfer characteristics Switching frequency < 10 Hz Galvanic isolation Input/Output reinforced insulation according to IEC/EN 61010-1, rated insulation voltage 300 Veff Input/power supply reinforced insulation according to IEC/EN 61010-1, rated insulation voltage 300 Veff Output/power supply reinforced insulation according to IEC/EN 61010-1, rated insulation voltage 300 Veff Indicators/settings Display elements LEDs Control elements DIP-switch Configuration via DIP switches Labeling space for labeling at the front Directive conformity Electromagnetic compatibility Directive 2014/30/EU EN 61326-1:2013 (industrial locations) Low voltage Directive 2014/35/EU EN 61010-1:2010 Conformity Electromagnetic compatibility NE 21:2006 Degree of protection IEC 60529:2001 Input EN 60947-5-6:2000 Ambient conditions Ambient temperature -20 ... 60 °C (-4 ... 140 °F) Mechanical specifications Degree of protection IP20 Connection screw terminals Mass approx. 150 g Dimensions 20 x 119 x 115 mm (0.8 x 4.7 x 4.5 inch) , housing type B2 Mounting on 35 mm DIN mounting rail acc. to EN 60715:2001 Data for application in connection with hazardous areas EU-Type Examination Certificate PTB 00 ATEX 2081 Marking # II (1)G [Ex ia Ga] IIC# II (1)D [Ex ia Da] IIIC# I (M1) [Ex ia Ma] I Input Ex ia Voltage 10.6 V Current 19.1 mA Power 51 mW (linear characteristic) Supply Maximum safe voltage 126.5 V AC (Attention!
