Product Description

The IC693MDL635 is a 125-volt DC Positive/Negative Logic Input module. This GE Fanuc module is specifically designed for compatibility in the RX3i system and can be installed into any I/O within the system. IC693MDL635 has dual logic characteristics – i.e. positive or negative and has 16 input points in one group with a common power input terminal.  When current flows into an input point, it produces a logic 1 in the status table of the input (%I).  The IC693MDL635 design input characteristics make it suited to and operational with a robust option of input devices, such as electronic proximity switches, pushbuttons and limit switches. Located on the top face the module are two horizontal rows with eight green LEDs.  On the upper row, the LEDs are labeled 1 to 8. The LEDs situated on the bottom row are labeled 9 through 16.  These LEDs communicate the “on” or “off” status of each input point to the user.

This 125-volt DC Positive/Negative Logic Input module has a rated voltage of 125 volts with a DC input voltage range of 0 to +150 volts DC.  Its isolation (field to Backplane, optical, and to frame ground) is 250 VACs continuous; 1500 VAC for one minute.  The input current when operating at the rated voltage is typically 1.97 mA.  IC693MDL635 has input characteristics that feature the on-state voltage of 90 to 150 volts DC while the off-state voltage is 0 to 30 volts DC.  The on-state current has a 1.41 mA minimum and the off-state current has a 0.46 mA maximum.  The and off response time is also typically 8 ms for each.  Power consumption at 5V is 80 mA (when all inputs are on) from a 5-volt bus on the backplane.  Power consumption at 125V is 31.5 mA from user-supplied power when all inputs are on at 125VDC.  To identify the module as a high-voltage module, there are red bands on the label.

For terminal block wiring, the torque must be in the range 9.6 to 11.5 in.-ib (1.08 to 1.30 n-M); the wiring -   copper conductors stranded or solid 90C rated, one 14-22 AWG or two 16-22 AWG.  Either solid or stranded wires, but not combined, are to be used in the same terminal.  Also, no combinations of different wire sizes are to be used in one terminal.
