GE FANUC IC697MDL653 Input Module

Features:

▪ 32 Points – Four isolated groups of eight points each

▪ Positive/Negative Logic Compatibility

▪ Proximity switch compatible

▪ Input filter selectable – 1 ms or 10 ms

▪ First input configurable as interrupt

The 24 Volt DC Positive/Negative Input Module provides 32 input points in four isolated groups of eight points each. The input current–voltage characteristics meet IEC standard (type 1) specifications.

LED indicators that show the ON–OFF status of each point on the logic (PLC) side of the circuit are located at the top of the module.

Input Characteristics:

IC697MDL653 has both positive and negative logic characteristics – it sinks or sources current from the input device to the user common. The input device is connected between the power bus and the module input as shown above. This module is compatible with a wide variety of input devices, such as:

▪ Pushbuttons, limit switches, selector switches;

▪ Electronic proximity switches, both 2 3–and 3-wire.

In addition, inputs on this module may be directly driven by a compatible voltage output module.

The input circuitry provides sufficient current to ensure reliable operation of the switching device. Input current is typically 10mA in the ON state. An input in the OFF state can accept up to 2mA leakage current without turning on.

Module Keying:

Earlier versions of this module included a mechanical key to prevent inadvertently replacing a module with another of the wrong type. The key latched onto the backplane center rail when the module was first installed, and remained on the backplane if the module was removed.

A new module without this keying feature can be installed in a previously-keyed slot without removing the earlier keying. However, the key is easily removed by pushing it upward to unhook the latch while pulling it off the rail.

The following procedures IC697MDL653 are recommended when connecting field wiring to the detachable terminal board on this input module.

1. Turn off the power before removing or installing terminal boards.

2. Open the hinged door on the module. The terminal board can be removed by turning the jackscrew counter-clockwise until it is disengaged.

3. To remove the terminal board, grasp the top of the terminal board and swing it outward.

4. The terminal board accepts wire sizes from AWG #22 (0.36 mm2 ) through AWG #14 (2.10 mm2 ). When using AWG #14 (2.10 mm2 ) wire for wiring all points, do not exceed a maximum insulation diameter of 0.135 inch (3.43mm). To ensure proper connection, two wires may be terminated on one terminal only if both wires are the same size.

5. The terminal board accepts a maximum of 40 AWG #14 (2.10 mm2 )wires. If AWG #14 (2.10 mm2 ) wires are used, place the wire at least 8 inches (203mm) from the termination end to provide space for the hinged door to close. After completing connections to all modules in a rack, the wire bundle must be secured. To ensure that the wire bundle is secured properly, it is recommended that a cable tie be wrapped around the wire bundle and tightly secured through the cable tie cleat at the bottom of the terminal board. For extremely large wire bundles, additional cable ties should be used.

6. The module's door label shows circuit wiring information and provides space to record circuit wiring identification. A slot is provided on the hinged door to allow for the insertion of this label. If the label is difficult to insert, crease the scored edge before insertion.
