The IC697MDL253 input module is manufactured by GE Fanuc and it belongs to Series 90-70. It operates on a voltage rating of 24 Volts AC and it has 32 input points in 4 isolated groups of 8 input points each. This allows for the use of every group on various AC supply phases. Some notable features of the IC697MDL253 input module include a 20-microsecond filter and it is compatible with proximity switches. This is a resistive input module that delivers 24 Volts AC to all 32 points in the 4 isolated groups. This input module has characteristics that are well-matched with different types of proximity switches. Also, the module comes with LED indicators that display the on and off status of every input point. It is mechanically keyed so that it can be easily and accurately replaced.

The GE Fanuc IC697MDL253 input module does not need DIP switches or jumpers for configuration. The configuration depends on the Windows NT or Windows 95 operating systems or the MS-DOS software through the SNP or TCP/IP port. Its programming software is preinstalled on the programming device. The GE Fanuc IC697MDL253 input module works with a wide range of input devices like the electronic 2-wire or 3-wire proximity switches, limit switches, and selector switches. It has 10 milliamps of input current in the on-state with a 2 milliamps leakage current in the off-state. The 3-wire proximity switches are preferred for this module because they offer low on-state voltage drops and low off-state current leakage. The GE Fanuc IC697MDL253 input module is designed and intended to work with the 2-wire devices, including the 2-wire proximity switches that are powered by the signal connections.
