Basic Installation & Usage

Mounting

Snap into standard I/A Series DIN rail or baseplate.

Secure latch; ensure full seating for backplane contact.

Wiring

Connect field devices (contact sensors, solenoids, relays) to TA.

DI: Dry contact or 15–60 VDC; common ground not required (isolated).

DO: External 12–60 VDC source; positive to load, negative to module.

Use shielded twisted pair; separate analog/digital cables.

Wiring size: 0.2–4 mm² (24–12 AWG); ferrules recommended.

Configuration (I/A Series Software)

Set DI debounce time and alarm thresholds.

Configure DO failsafe state (hold / ON / OFF).

Enable diagnostics (open load, short circuit, overcurrent).

Assign redundancy role (primary/secondary) if applicable.

Operation

RUN (green): module ok; FAULT (red): error (comms/power/channel).

Channel LED: ON = active; FLASH = fault (short/open/overload).

Monitor DI status and DO commands in HMI.

Maintenance

Hot‑swap faulty module (no shutdown; TA wiring intact).

Inspect TA wiring, shields, and grounds annually.

Update firmware via I/A Series software.

Calibration: Not required (factory‑calibrated; on‑board diagnostics).

Typical Applications

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

Status monitoring of limit switches, pressure switches, and dry contacts.

Interface to 24–60 VDC discrete devices in process industries.

Migration of legacy FBM03/FBM08 to 200‑series FBMs.
