Resolution: 12 bits (4095 steps)

Load capacity:

Source mode: ≤ 550Ω (including line resistance)

Sensing mode: ≤ ((UQ - 10V) / 2) / 21.2mA (UQ = 10~30V DC)

Accuracy:

Basic error: ≤ ±0.2% FS (40μA) @ 25℃

Operating error: ≤ ±0.4% FS @ 0~+60℃

Isolation withstand voltage: 250V AC (channel to analog ground)

Power supply: 5V DC ≈ 85mA; 24V DC≈130mA

Operating temperature: -20℃ ~ +60℃

Dimensions/Weight: 4TE (25×203×127mm) / Approximately 0.5kg

Installation: DIN rail, supports hot swapping

Diagnosis: Output short circuit / open circuit / over-range detection, automatic full test during operation

II. Relationship with the standard version F6705 (984670501)

F670532 (984670532): Hardware/firmware upgrade, enhanced diagnostics and stability, batch update, fully interchangeable

F6705 (984670501): Standard version, functionally identical

III. Key points (Installation / Wiring / Maintenance)

1. Installation essentials

Environment: Dust-free, dry, free from corrosion, anti-condensation

Heat dissipation: Maintain a spacing of ≥ 50mm between top and bottom, keep away from heat sources and strong electricity

Grounding: Independent protection ground of the cabinet ≤ 4Ω, separate system ground from protection ground

Hot swapping: Before online replacement, disable the module in the software

2. Wiring specifications (28-pin terminals)

Signal cables: Shielded twisted pair, single-ended grounding (module side)

Cabling: Separate the wiring from strong electricity by ≥ 10cm, avoid long parallel runs

Maximum cable length: 1000m (load resistance needs to be verified)

3. Configuration and calibration

Software configuration: ELOP II sets output type, range and fault safety value

Calibration cycle: Suggested once a year; re-calibrate if error exceeds ±0.2% FS

Safety shutdown: Automatically cuts off output and enters safe state upon failure

4. Maintenance and fault troubleshooting

Status indication: Green LED = normal, red = fault; regularly check diagnostic logs

Common faults:

Incorrect output: Check wiring, shielding, grounding and load resistance

No output from channel: Check short circuit / open circuit, replace the channel for testing, if abnormal, replace the module
