Z7138 | HIMA Front cable plug

The module is automatically tested during operation. The main test routines are:– Reading back of the output signals. The operating point of the 0 signalread back is ≤ 6.5 V. Up to this value the level of the 0 signal may arisein case of a fault and this will not be detected– Switching capability of test signal and cross-talking (walking-bit test).Outputs 500 mA, k short circuit proofInternal voltage drop max. 2 V at 500 mA loadAdmissible line resistance (in + out) max. 11 OhmUndervoltage tripping at ≤ 16 VOperating point for short circuit current 0.75 … 1.5 AOutp. leakage current max. 350 µAOutput voltage if output is reset max. 1,5 VDuration of the test signal max. 200 µsSpace requirement 4 TEOperating data 5 V DC: 110 mA24 V DC: 180 mA in add. load
