The 120 Vac Input module, IC694MDL240, provides sixteen input points with one common power input terminal. The input circuits are reactive (resistor/capacitor) inputs. Current passing into an input point results in a logic 1 in the input status table (%I). Input characteristics are compatible with a wide range of input devices, such as pushbuttons, limit switches, and electronic proximity switches. Power to operate the field devices must be supplied by the user. This module requires an AC power source; it cannot be used with a DC power source. Sixteen green LEDs indicate the ON/OFF status of points 1 through 16. The red bands on the label show that MDL240 is a high-voltage module. This module can be installed in any I/O slot in an RX3i system. Module supports insertion into and removal from an RX3i Universal Backplane which is under power.
