Board Layout and Components
The PCB separates input conditioning circuits from output driver stages. Four input channels share a single 12-bit ADC via a multiplexer. Moreover, 264 discrete components include precision resistors and isolation barriers. Tantalum capacitors provide stable references for accurate conversions. Consequently, the module maintains reliable performance in remote field locations.
Installation Process
You can mount GE IC660ELA100 inside Genius I/O field blocks. The RS-485 network connects directly to a Genius bus controller. Furthermore, removable terminal blocks accept field wiring for all six channels. Configuration software sets input and output ranges per channel easily.
Performance Advantages
This module combines four inputs and two outputs in a single package. The 12-bit resolution captures process signals with adequate precision. Therefore, remote applications save rack space and wiring costs. The rugged design also withstands extended temperature ranges in non-conditioned areas.
Safety and Compliance
GE IC660ELA100 meets CE and RoHS industrial standards. The board discharges stored energy below 3V within five seconds. Hence, technicians face minimal electrical risk during field servicing.
