Product details

The 6AG1331-7TB00-4AB0: Onboard diagnostics include per-channel limit-value alarms, an overrange red LED, a group error SF indicator, and a green LED for active HART communication. The module can read back HART variables without an external HART modem, cutting wiring and panel space.

Key approvals and ratings for specification

Certified for ATEX Zone 2 / Div. 2 (KEMA 97 ATEX 3039X), with FM Class I Div. 2/Zone 2 approval available. Loop supply is 15 V DC at 22 mA with reverse-polarity protection; power consumption from the backplane is 100 mA at 5 V DC and 4.5 W total. Maximum ambient temperature of 60 °C (Tmax) broadens installation options, though derating curves apply above 40 °C. The module is short-circuit proof each channel (30 mA clamp) and provides galvanic isolation between channels.
