Mechanical Data

‑ Weight：approx 0.90 kg ‑ Dimension：224 × 90 × 100 mm ‑ Handling note：ESD‑sensitive mating connector; anti‑static wrist‑strap mandatory during handling ‑ Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Provide field‑wiring termination interface for 6‑channel 4‑20 mA analog transmitters and control instruments.
2. Carry local block power input and Genius‑bus daisy‑chain bus terminals; host rotary address switch for Genius‑bus slave station address setting.
3. Separable mechanical structure: electronics unit can be pulled out for maintenance without removing field instrument cables.
4. Transfer analog field signals and Genius‑bus signals to mated IC660EBA026 electronics assembly via edge connector.

Installation & Wiring Requirements

1. Cut off block local 115VAC/125VDC power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling terminal base.
2. Mount IC660TBA026M firmly on panel or DIN‑rail; insert and lock IC660EBA026 electronics assembly; set Genius‑bus rotary address switch consistent with master configuration.
3. Analog‑loop and Genius‑bus wiring strictly follow GE Genius hardware manual; use shielded twisted‑pair cable for analog and Genius‑bus; install bus terminator resistor at both physical ends of Genius trunk; separate signal cables from high‑power cables, connect shielding to dedicated protective ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement: power‑on whole block, verify block self‑test status, perform full‑channel analog‑signal continuity test.
6. Replacement note: Verify mechanical compatibility with electronics assembly; full analog‑loop simulation test mandatory before unit put‑into‑service.
