Note: The Voltage/Current mode switch is located directly
above each input. Moving a switch towards Pin 1* selects

±

20mA for the corresponding channel. Moving the switch

towards Pin 12 selects

±

10VDC. Each channel must be set

up in Cscape for the desired mode in addition to the physical
switch settings for proper signal scaling in the PLC registers.
