Product Description

IC694MDL250 is a 120 VAC 16-Point Isolated Input Module by GE Fanuc
. The 16 isolated input points can be used on different phases of the AC supply or powered from the same supply. An RC snubber protects the inputs against transient electrical noise that may be present on the power line. Input filtering time on the module can be changed during operation by the application program. DIP switch settings are not required.
The IC694MDL250 module can be used with a box-style (IC694TBB032), extended box-style (IC694TBB132), spring-style (IC694TBS032), or extended spring-style (IC694TBS132) terminal blocks. Extended terminal blocks provide extra shroud depth generally required for field wiring to AC devices. Note: Terminal blocks are ordered separately.

Individually numbered LEDs on the module show the ON/OFF status for individual input points. The TB LED is green when the removable terminal block is appropriately locked and red when the terminal is not locked. Red bands situated on the door card warn the user that the IC694MDL250 is high-voltage. This module can be installed in any I/O slot as part of the RX3i system. It must, however, be used with RX3i CPU release 3.50 or later and is not compatible with a Series 90-30 PLC CPU. If an input filter time is applied to all of the module’s inputs, input filtering should be enabled in the module’s software configuration. The Digital Filter Settings Length must be at 16, and a memory location value must be identified. Configuring a Digital Filter Settings Length of 0 will disable the input filter.
