Note: Some distributors list the 51402615-400 as a safety system power supply module (85–264 V AC input, 24 V DC / 10 A output, 240 W). The LCN analog input module definition above is the more widely documented identity for this part number in TDC 3000 contexts. Verify the exact variant with the supplier based on your system configuration.
Functional Characteristics:
- Software-selectable filtering
- Three-wire or four-wire connection support
- High-precision acquisition for demanding process industries
- EMC-hardened for stable operation in strong electromagnetic environments
Application Scenarios: Reactor temperature and pressure monitoring in chemical and petroleum industries with PID closed-loop control, and other high-precision analog data acquisition duties.
Installation Requirements: Insert into the designated LCN card slot in the TDC 3000 cabinet. Ensure proper earthing and separation from high-voltage wiring.
Usage Notes: Confirm the input wiring type (voltage vs. current) and resolution settings in the system database before commissioning.
