Analog Output Specifications
Note 1: Values in ( ) represent analog I/O modules earlier than version 200. For analog I/O module version, see page 2-44.
Note 2: The data processed in the analog I/O module can be linear-conver ted to a value between –32768 and 32767. The
optional range designation, and analog I/O data minimum and maximum values can be selected using data registers allo-
cated to analog I/O modules. See page 24-12.
Note 3: For analog I/O modules of version 200 or higher, the value represents when 1 kV is directly applied to the power
supply line and a 1 kV clamp voltage is applied to I/O lines. For analog I/O modules earlier than version 200, the value rep-
resents when a 500V clamp voltage is applied to the power supply and I/O lines.
