Note. An external voltage divider (part no. GR2000/0375) is required for each channel on which 'Input type' is set
to 'Voltage' – see Sections 4.6.2 and 5.4.1.
Information.
• Always route signal leads and power cables separately, preferably in earthed
metal conduit.
• It is strongly recommended that, for signal inputs and relay connections,
screened cable is used, with the screen connected to the earth stud.
• The terminals accept cables up to 2.5mm

*Note. An external divider (part no. GR2000/0375) is
required for each channel for voltage input ranges above 2V
