5.8 Analogue input module
Note:
} Use shielded, twisted pair cable for the connections on the input current circuits.
} Separate the supply voltage cable from the analogue input current lines.
} For transducers located outside the control cabinet: Where the cable enters the control
cabinet, the cable shield must be connected to the earth potential over a wide surface
area and with low impedance (connect in star).
