Material Composition: Fiberglass epoxy multilayer printed circuit board; surge‑suppression gas‑discharge tube; signal filtering resistor‑capacitor components; optoelectronic isolation chip; gold‑plated backplane connector; metal front panel; detachable spring‑loaded wiring terminal; three‑proof conformal coating on circuit‑board surface.
Structural Features: Standard rack plug‑in large‑size card‑type structure; both sides of module equipped with detachable field‑signal wiring terminal blocks; rear gold‑plated connector is connected with system backplane bus; internal field signal circuit and system logic circuit implement physical isolation; front panel equipped with mechanical locking device to prevent vibration‑caused contact looseness.
Working Principle: Field instruments, switches and actuator signals connect to TIU6 external wiring terminals. Signals pass surge suppression, filtering and isolation circuit inside module, and then transmit to corresponding I/O module through backplane connector. When field side generates surge or over‑voltage signal, internal protection components activate to clamp abnormal voltage, prevent damage to DCS internal I/O card. Module keeps signal transmission integrity and completes signal level matching.
Installation Requirements: Insert A413110 TIU6 module into designated slot of Metso DNA rack, and make rear connector fully engage with backplane. Field signal wiring adopts shielded cables, shielding layer single‑point grounding. Signal cables separate from high‑power power cables during cabling. Cabinet protective grounding terminal must connect reliably. Reserve enough surrounding space for module heat dissipation.
Precautions for Use: Cut off rack backplane power and field signal loop power before wiring and maintenance. Wear anti‑static wrist strap when operating module. Do not feed over‑range high‑voltage signal into terminal channel. Inspect tightness of wiring terminals periodically. Prevent dust accumulation on wiring terminals. Avoid condensation inside control cabinet.
