Channel Configuration and Signal Flow
Moreover, the GE IC660EBD025 divides its 16 channels into two isolated groups. The first group handles eight digital inputs. Each input accepts 24 VDC signals from proximity switches or pushbuttons. The second group provides eight digital outputs. Those outputs drive indicator lamps, relays, or small solenoids. Therefore, one module covers basic machine control tasks.
Energy Storage and Power Management
For stable operation, this module stores 680 µF of energy. Two aluminum electrolytic capacitors provide this storage capacity. One 470 µF capacitor filters the input power line. The other 210 µF capacitor supports the output drivers. This arrangement prevents voltage drops during simultaneous output switching. Consequently, the GE IC660EBD025 maintains consistent logic levels.
Physical Construction and Component Layout
Furthermore, a polycarbonate housing encloses all 86 components. Inside, you will find a single four-layer printed circuit board. That board hosts an isolation transformer and optocouplers. These components separate the input field wiring from the backplane logic. A metal shield reduces electromagnetic interference from nearby drives. This design ensures reliable data transmission in noisy panels.
Installation and Field Wiring Details
You can mount the GE IC660EBD025 on a DIN rail or using panel screws. A removable screw clamp terminal block simplifies field wiring replacement. Each input channel requires only two wires for connection. Likewise, each output channel uses two wires for the load circuit. Always use 18 AWG copper wire for field terminations.
