HONEYWELL MC-TAIH52 51304337-250 Analog Input Board

One-line benefit

Data

Channel density

16 fully isolated AIs, only 22.5 mm on DIN rail

Redundancy

Dual-cable inlet, no jumpers, 30 s change-over

Hazardous area

Class I Div 2 / Zone 2, -20 °C to +60 °C, mount on site

Accuracy

±0.075 %, 14 effective bits, 4× better than 12-bit cards

Transmitter power

30 mA per ch, 23 V min, eliminates extra supply & fuses

Pain

Traditional way

MC-TAIH52 answer

Surge kills board

External surge device

Built-in IEEE C37.90.1 4 kV path, passes test naked

Ground loops

Single-ended, noisy

3-way isolation: ch-ch, ch-system, field-system

Redundancy = shutdown

Re-term, re-check wires

Dual-cage clamps, hot-swap, zero downtime

Crowded panel

8-ch FTA + barriers

One 16-ch slice, same width as one barrier

Requirement
