Recommended wire size for terminating field signal wires are AWG #14 (avg 2.1mm2 in cross-section) with minimum recommended size of AWG #20 (avg .54mm2 in cross-section). For serial bus wiring, recommended wire size is AWG #12 wire (avg 3.3mm2 cross-section) for single wire connection and AWG #14 wires (each avg 2.1mm2 in cross-section). When 2 wires are needed in a single terminal. Minimum recommended wire size for serial bus is AWG #22 (avg .36mm2 in cross-section).

The IC660BBA105 module is a Genius I-O module that is compatible with the Series 90-30 PLC system by GE Fanuc. The module has a total of 32 terminals and 6 output blocks. The resolution of the module is 6 microAmps. It comes with 6 points and the operating voltage of the module is 93 to 132 Volts AC and 105 to 145 Volts DC. The output range of the I/O module is 4 to 20 milliAmps or 0 to 24 milliAmps. This Genius I-O analog device has an open enclosure and it should be protected against water splashes and air-borne contaminants. The IC660BBA105 module is 8.83 inches in height, 3.50 inches in width, and 3.94 inches in depth. The front of the module is equipped with a Unit OK LED and an I/O Enabled LED.

The IC660BBA105 module has a block to block isolation of 1500 Volts for a time period of 1 minute. For regular operation, the I/O module generates 12 Watts of heat as energy dissipation. The temperature of the module’s environment should not exceed 60 degrees Celsius. The IC660BBA105 module uses the monitoring port to connect with a handheld programming unit. The operating frequency of the I/O module is 50 to 60 Hertz. It is equipped with Serial 1, Serial 2, Shield In, and Shield Out connection ports. The I/O block has independent circuits that are electrically common but that are isolated from other circuits. The IC660BBA105 module features one of the enhanced diagnostic features in an I/O block that can easily detect no-load errors, overload errors, short-circuit errors, and other errors. The module has a baud rate of 76.8 and 38.4 kbaud.
