Material Composition： Flame-retardant UL94-V0 engineering plastic front panel; FR-4 high-Tg industrial printed circuit board; gold-plated backplane connector pins; nickel-plated screw output terminals; high-precision DAC chipset.

Structural Features： Standard rack-insertion card structure; front panel with channel status LED indicator array; rear side high-density backplane connector; built-in shielding metal frame to reduce electromagnetic interference; integrated fixing buckle for reliable rack installation.

Working Principle： Receives digital control commands from the host controller through the system backplane, converts digital values into corresponding analog voltage or current signals via the internal high-precision DAC circuit, and outputs the signals to field actuators through the isolation output circuit. The internal diagnostic circuit monitors the output state in real time and uploads fault information to the controller when abnormal conditions occur.

Installation Requirements： Install into the dedicated TEL equipment rack slot; ensure the rack is reliably grounded for electrostatic and interference protection; use shielded cables for field output wiring with single-end grounding at the cabinet side; separate analog signal cables from high-voltage power cables; reserve 10 mm upper and lower clearance for heat dissipation; wear an anti-static wrist strap during installation.

Precautions： Do not exceed the maximum output load capacity of each channel; avoid short-circuiting the output terminals directly; do not connect input signals to output terminals; perform regular calibration according to equipment maintenance cycles; do not disassemble the module for repair, replace the whole unit in case of hardware failure.
