The module assigns memory locations for the DL240, DL250-1 and DL260 CPUs. The V-memory locations define the scanning of the I/O channels, define the storage location for the input data, and specify the output data source location.
Features include the following:
The analog inputs are optically isolated from the PLC logic.
Easily uninstall the the terminal block and reinstall it.
One scan can update all channels if a DL240 CPU, DL250-1 CPU, or a DL260 CPU is used.
Over-current protection for 4–20mA current loops is included with the module..
The input range in amperage is between 4 and 20 mA. The number of input channels is 4, single ended (one common). The resolution is 12 bit (1 in 4096). The power budget requirement is 60mA @ 5VDC (supplied by the base). The environmental air requirement is no corrosive gases permitted. The operating temperature 0-60°C (32-140°F). The relative humidity 5–95% (non-condensing).
The PLC update rate for the input, output, and combination:
D2-240/250-1–1/260 CPU: 4 input channels/scan or less
D2-240/250-1–1/260 CPU: 2 output channels/scan or less
D2-230 CPU1 input and 1 output channel/scan or less
