F3237 | HIMA Digital Input Module

The module is automatically tested completely during operation. The maintest routines are:- Switch on and switch off cability- Crosstalk of the input circuits by walking 0 test- Function of the input filters- Correct function of the module- Short circuit and wire break of the sensor lineFunction of LEDs are not tested.Appertaining softw. building block: HB-RTE-. (for current version refer tothe description of the operating system).Switching time approx. 10 msOperating points IE 0 signal 0.35 ≤ IE ≤ 1.2 mA 1 signal 2.1 ≤ IE ≤ 6.0 mA wire break ≤ 0.28 mA short circuit ≥ 6.5 mALine impedance ≤ 50 Ohm (acc. to DIN 19234)Line length ≤ 1000 m (∅ = 0.5 mm2)Supply voltage US 8.2 VShunt R* 681 Ohm; 1 %; 0.25 W(R17 … R24) part no. 00 0751681Space requirement 4 TEOperating data 5 V =: 90 mA; 24 V =: 170 mA
