GE IC660EBA106 Analog Output Block – 8-Channel Current/Voltage Source

This analog output block converts digital commands into precise field signals. It serves the GE Genius I/O family for distributed control applications. You will find this unit ideal for valve positioning or drive speed control.

Key Technical Specifications

Physical Construction and Mounting

This block measures 230 mm in width and 160 mm in height. Its depth reaches 45 mm for panel or rack installation. The unit weighs 1.1 kg, indicating robust internal shielding. Four mounting tabs accept M6 screws for secure attachment.

Internal Design and Energy Storage

One hundred forty-five components populate the internal analog circuitry. A 3300 µF capacitor bank stores energy for output hold-up during bus scans. Consequently, the block maintains last-known output values for 20 milliseconds. This feature prevents sudden valve closures during brief communication interruptions.

Output Interface and Configuration

The analog block delivers eight individually configurable output channels. You can select 4–20 mA current loop or 0–10V voltage mode per channel. Twelve-bit resolution gives you 4096 discrete steps for smooth control. A Genius LAN terminal block handles two-wire bus communication with the host controller. Each channel also includes transient protection diodes for field wiring safety.

Power and Operational Limits

The block accepts a 24V DC supply with ±10% tolerance. It draws 120 mA maximum plus 20 mA per active output channel. Therefore, total current reaches 280 mA when driving all eight outputs fully. The operating temperature ranges from 0°C to 55°C for industrial floors.
