The incorporated opto-coupler separates this input from the subsequent circuit. The output of the unit repeats the input pulse signals, with inverted sequence but enforced level, to feed electronic measurements, alarms, totalizers, or controllers. ATEX II (1) G [Ex ia] IIC CE 0123 TPS 03 ATEX intrinsic safety connection to pulse transmitting sensors The input circuit is approved for safety grade (Ex ia) IIC, according to ATEX certificate No. TPS 03 ATEX 1 006, on European Standards. Characteristics of the input circuit immediately match the specifications of the speed sensor series A5S1..., which are approved as intrinsic safety devices, to be installed in a hazardous area if properly supplied. The barrier unit D461 must be placed in a safe (non-hazardous) area, or within an explosion-proof enclosure. A sensor A5S1., in combination with the barrier D461 thereby establishes an efficient speed sensing system, to supply high level output signals to the periphery. Installation The barrier D461 is designed for indoor use (NEMA 1). Screw mounting, or snap on track (DIN 35 mm) can be used. Protection grade IP20. As a special version, the barrier is available in enclosure grade IP65 (NEMA4), or in explosionproof enclosure (Exd II C T5). Allowable ambient temperature C. Weight approx. 0,4 kg. Signal Input Response level (low < 1.8 volts, high > 3.5 volts. Input impedance 47k. Input capacitance Ci and inductivity Li are negligible. Sensor supply: 8 volts (operational value). Approved maximum values: (according to certification) Uo = 8,7 V Io = 62 ma Co = 300 nf Lo/Ro = 883uH/ohms Lo = 2mH Po = 130mW installation requirements input data cable specifications Sensor connection by 3 leads shielded cable, recommended LiY Y 3x0,5 or larger.

2 Signal Output Active pulses by push-pull transistor output stage, sequence inverting the input signal. output data Output level, with load 500 Ohms towards 0 volts (common zero): high approx. 18 volts low approx. 0 volts with load 500 Ohms towards 24 volts : without load: high approx. 20 volts low approx. 2 volts high approx. 19 volts low approx. 1 volts Sensor supply circuit monitoring The sensor supply circuit is monitored against lead break and short circuit. A fault is announced by alarm relay. An additional transistor output is non conductive in case of fault. The transistor output can be connected to the sensor supply of a subsequent module, thus enabling its own sensor supply circuit monitor. Sensor supply circuit monitoring Power Supply D461.21U1: volts ac or dc, power requirements approx. 3 watts. D461.21U2: volts ac, power requirements approx. 3watts power supply Circuits Isolation Input, output, and power supply are isolated against each other. The output circuit must not be connected to other devices having an operational voltage exceeding 375 volts (peak). isolation data Intrinsic Safety Certification Grade (Ex ia)ii C, according to standards EN 50020: 1994, EN 50014: Certificate: ATEX TPS 03 ATEX D Manual_EN_Rev Page 2 of 7
