10102/2/1 | Honeywell Fail Safe Analog Input Module

The fail-safe analog input module 10102/1/1 has four 0(2)-10 V /0(4)-20 mA analog input channels. The analog inputs have a common0 V connection, but are galvanically isolated from the 24 Vdc and the5 Vdc.The analog inputs can either be used actively (i.e. each input has aseparate 26 Vdc, > 20 mA short-circuit protected output) or passively(i.e. the supply is directly connected to the transmitter).The 10102/1/1 input stage has a low input impedance for current(100 Ohm). It is therefore not allowed to connect 10102/1/1 modulesin parallel in the mA range, as this will considerably affect themeasured value. If parallel operation in the mA range is required, theanalog input module 10102/1/2 must be used.
