Electrical parameters

Power supply voltage: 24VDC (range 18~32VDC)

Power consumption: Typical 19.2W

Input side: 16 DI channels, no isolation, high level 15~30VDC, low level ≤5VDC

Output side: 8 DO channels, no isolation; 2A per channel at 40℃, 1A at 60℃; maximum total current 8A

Sensor power supply: 4 × 19.2V/40mA, short circuit protection

Communication interface

Ethernet: 2×RJ45, 10/100Mbps, supports Modbus TCP

Backplane bus: Connects HIMA system backplane to achieve data interaction

Environmental parameters

Operating temperature: 0℃ ~ +60℃

Storage temperature: -40℃ ~ +85℃

Relative humidity: 5%~95%, no condensation

Explosion-proof certification: Ex II 3 G EEx nA II T4 X Core function

I/O signal acquisition and output: 16 digital input channels collect on-site switch signals, and 8 digital output channels drive on-site actuators (such as solenoid valves, indicator lights).

Safety circuit control: used for ESD emergency stop, BMS burner management, F&G fire gas detection, etc., in SIS system safety control circuits.

System redundancy and diagnosis: supports TMR triple redundancy architecture, with hardware self-diagnosis coverage ≥ 99%, and automatically switches redundant links in case of faults.

Hot-swappable: replace modules online in the rack, and automatically synchronize configurations after replacement, without the need for downtime reconfiguration.

Panel indicator lights

PWR (green): Normal power supply

RUN (green): Module running normally (flashing)

ALM (red): Hardware or communication fault alarm

ETH (yellow): Ethernet data transmission and reception

DI (green): Digital input channel status

DO (green): Digital output channel status

Installation and maintenance

Push the rack slot in steadily and lock it to ensure reliable contact of the backplane

Connect 24VDC power supply, on-site I/O signals, and Ethernet interface according to specifications, and reliably ground the cabinet

Check the status of indicator lights during daily inspections, regularly tighten terminals, and clean module dust

Replace the same model F8640 directly when there is a fault, without modifying programs and wiring
