Product Description:
Digital input and digital output modules are I/O modules which allow the
processing of widely differing process signals with the S5-135U/155U
programmable controller. They can also be used via an adapter casing in the
S5-115U PLC.A digital input module converts the process signals to the internal signal
level in the module. Interference is suppressed by the input circuitry, and the
logic states at the inputs are indicated with LEDs on the front strip of the
module. With most digital input modules (except the 420), the signals are
isolated from the central ground point when received. Inputs relating to the
same group are isolated from inputs of another group, but not from each
other.
