Description
The GE IC660BBA020 is a high-density analog input/output block from GE Fanuc’s Genius I/O series, designed as a standalone, rack-mounted module for distributed industrial control systems. It combines four voltage/current analog inputs and two analog outputs in a single unit, enabling precise acquisition and control of process variables like pressure, temperature, flow, and level in factory automation, material handling, and OEM machinery. Compatible with all Genius bus PLCs (Series 90-30/70, VersaMax, RX7i), it connects via a serial Genius bus for configuration, diagnostics, and data exchange, supporting independent scaling, alarming, and filtering per channel without host CPU intervention. The module’s rugged construction suits harsh environments, with conformal coating, wide power tolerance, and extensive fault reporting via LEDs and bus diagnostics, making it ideal for standalone remote I/O drops where wiring economy and reliability trump centralized cabinets.

Product Parameters
IC660BBA020 requires 24/48 V DC power (18-56 V operating range, 8 W typical / 10 W max), self-powered for field circuits with internal excitation capable of driving 300 Ω current loads. It features four isolated analog inputs (0-10 V DC, ±10 V DC, ±5 V DC, 0-5 V DC, 4-20 mA/1-5 V DC selectable per channel) and two outputs with identical ranges, all 12-bit + sign resolution (±0.2% FS accuracy typical, ±0.5% max). Input impedance is >200 kΩ voltage/>250 Ω current modes; output compliance voltage reaches 12 V at 20 mA. Update rates achieve 4 ms full scan, with configurable digital filters (none to 1024 ms, octal steps 8-1024 ms). Diagnostics include underrange/overrange, high/low alarms, open-wire detection (current mode), and fault reporting to bus master. Physical specs: 22.4 cm L x 8.9 cm W x 10 cm H, 1.8 kg; operating -30°C to +60°C, storage -40°C to +85°C, 5-95% RH non-condensing, 1 g/10-200 Hz vibration, 15 g shock. Block isolation: 1500 V (6 W dissipation); bus terminals AWG 22-14 (1-4), field AWG 22-14 (5-32). LEDs indicate Unit OK, I/O Enabled; compatible with HHM500 handheld monitor.
Datasheet Overview
Datasheet electrical ratings confirm 98-132 VAC option (10 VA, 47-63 Hz, 1-cycle dropout tolerance) alongside DC primary. Input resolution: 12-bit + sign (5 mV LSB on 10 V, 1 µA LSB on 20 mA); output same with 2000 Ω voltage/300 Ω current compliance. Temperature coefficient: 10 ppm/°C typical, 40 ppm max; common mode rejection >60 dB 0-1 kHz. Configuration via Genius bus sets scaling (engineering units/direct %), alarms (±% FS), defaults on power-up, and filter constants. Mechanical: terminal assembly only (IC660TBA020), electronics (IC660EBA020); fuse 1/8 A slow-blow 250 V AC/DC on AC models. Ground terminals (5,12,20,28) ensure shielding; jumper (JMP) configures source/sink. Wiring: voltage V+/IN to V-/RTN series, current I+/I-; output COM/VOUT. EMC: industrial Class A; safety UL/CSA listed. Block-to-block isolation 1500 V; max continuous 170 V. Update frequency: inputs every 4 ms, outputs match scan.
Origin
GE Fanuc manufactures the IC660BBA020 at facilities in the United States, reflecting the Genius I/O series’ North American production heritage for global factory automation markets.
