System compatibility
IC660BBA021 belongs to GE Fanuc Genius distributed I/O family. Compatible with Series90-70 / Series90-30 / RX3i PLC CPU with Genius bus adapter. Widely used for power plant,chemical,water treatment industrial temperature measurement and monitoring.
Function
IC660BBA021 is remote RTD temperature input block manufactured by GE Fanuc. It is part of Genius distributed I/O system. It reads resistance signal from field RTD temperature sensors, performs built-in linearization to calculate actual temperature value, then transmits temperature data to PLC controller via Genius serial bus. The module detects sensor open/short circuit and triggers alarm. LED indicators display module operating health status.
Installation
Follow lockout/tagout safety procedure before installation. Fully cut off block power. Mount IC660BBA021 on DIN rail. Connect 24/48VDC power supply, RTD sensor field wiring and Genius bus cable. Set block address and sensor type configuration via HHM handheld monitor. Power on, verify bus communication and temperature reading.
Interface
Genius bus terminal, 6 channel RTD sensor terminal, HHM service port, power terminal, on-board status LED indicators for GE Fanuc IC660BBA021.
Feature
