Basic Installation & Usage

Mounting

Snap into standard I/A Series rack baseplate.

Ensure full seating and secure latch.

Wiring

Connect field devices to Termination Assembly (TA).

Use external power (15–60 VDC / 120/240 VAC) for outputs.

Separate low‑signal cables from high‑power cables.

Each channel is isolated; no common ground between channels.

Configuration (I/A Series Software)

Set output mode: Normal / Failsafe.

Define failsafe state (ON/OFF) for each channel.

Set response time (10–100 ms).

Enable/disable short‑circuit detection.

Operation

Check module LEDs: RUN (green) = ok; FAULT (red) = error.

Check channel LEDs: ON = output active; FLASH = fault.

Monitor status in HMI; acknowledge alarms.

Maintenance

Hot‑swap faulty module (no shutdown required).

Inspect TA wiring and fuses periodically.

Update firmware via I/A Series software.

Typical Applications

On/off control of motor starters, solenoid valves, and contactors.

Alarm annunciation and interlock systems.

Lighting and HVAC control in industrial facilities.

Replacement for legacy FBM29 or FBM27 modules in I/A Series migrations.
