The GE Fanuc manufactured IC660BBD020 sink I/O module is a 3-wire sensor compatible device. The block includes 16 circuits and is rated for voltages between 24 and 48 volts. The GE Series 90-30 PLC platforms are compatible with this module. With the use of a controller or a handheld monitoring device, it may be readily configured and monitored. It may also be linked to a Windows-based personal computer. The load rating for the component is 2 amperes at the moment. Different important tasks such as Overload, No-load, Short circuits, Over-temperature, and failed switch conditions are all monitored by the IC660BBD020 I/O block's sophisticated diagnostic testing system. The configuration can be used as a tri-state input, output, or input/output device. The Module's input filter time may be set from 10 to 100 milliseconds. The block's sophisticated diagnostics system makes it simple to diagnose problems and mistakes during installation and use.
 The input processing time of the GE IC660BBD020 I/O block is 5.6 kilo-ohms between the voltages of 24 and 48 Volts and 1.8 kilo-ohms for 24 Volts rating of voltage. With a filter delay, the block's input impedance is 1.7 milliseconds. The I/O block is composed of open architecture and is solely intended for indoor use. With appropriate airflow over the block, the maximum ambient temperature should not exceed 60 ° C. EMC interference, and heat-generating equipment must be kept far away from the IC660BBD020 I/O block. The Module may be simply installed both horizontally and vertically. Star washers are used to improve ground stability. The I/O block is backward compatible, meaning it may be used with earlier PLC systems as well.
