Fanuc IC693MDL742 PLC

The 12/24 volt DC Positive Logic 1 Amp Electronic Short Circuit Protection (ESCP) Output module for the Series 90-30 PLC provides 16 output points in two groups of eight with a common power output terminal for each group. This output module is designed to have positive logic characteristics in that it sources current to the loads from the user common or positive power bus.

The output device is connected between the negative power bus and the module output. The output characteristics are compatible with a wide range of user-supplied load devices, such as: motor starters, solenoids, and indicators. Power to operate the field devices must be supplied by the user. LED indicators that provide the ON/OFF status of each point are located at the top of the module. This LED block has two horizontal rows with eight green LEDs in each row with the top row labeled A1 - A8 (points 1 through 8) and the bottom row labeled B1 - B8 (points 9 through 16). A red LED (labeled “F”) on the right, centered between the two rows of green LEDs, functions as a tripped electronic short circuit protection indicator; it turns ON when any short circuit protection trip occurs. The common signal for each group is monitored electronically. If a short circuit occurs, the output points in the group turn off and the red LED turns on. The LEDs indicating output point status will not turn off. This protection does not protect individual outputs from exceeding their ratings, but will protect the board in case of a short circuited load. To reset electronic short circuit protection remove the 12/24 VDC user supply to the module. The module has two electronic short circuit protection circuits; each protects eight outputs - the first circuit protects A1 - A8, the second circuit protects B1 - B8.

An insert goes between the inside and outside surface of the hinged door. The surface towards the inside of the module (when the hinged door is closed) has circuit wiring information, and circuit identification information can be recorded on the outside surface. The outside left edge of the insert is color-coded blue to indicate a low-voltage module. There are no fuses on this module. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system.
