| 2-CHANNEL ANALOG INPUT MOUDLE 4-20 mA CARRIER RAIL DIN 35 CAGE CLAMP CONNECTION |
| The analog input module is able to provide power to the field device, receive the transmitted analog signals, and with electrical isolation, transmit them to the fieldbus. The 24 V supply is derived from the power jumper con-tacts. The shield (screen) is directly connected to the DIN rail. At approx. 25 mA the overload protection switches the measurement input to a high resistance state. Under normal operating conditions it is automatically switched back. This input module can supply the voltage for 2-conductor transducers. |
