Features

Dual-channel (two independent universal sensor inputs) supporting RTD, resistance (Ω), thermocouple (TC) and millivolt (mV) signals.
Communication interface: PROFINET with Ethernet-APL (2-wire AT IEEE 802.3cg 10BASE-T1L) for field-level digital communication.
Designed for head-mounting in terminal head form B (flat‐face) per DIN EN 50446, and optionally in field housing (e.g., for Ex d installations) for hazardous areas.
High accuracy: for instance Pt100 in range –50…200 °C has accuracy ≤ 0.1 K.
Advanced diagnostics: sensor monitoring (e.g., corrosion monitoring of sensor wires), device-hardware fault recognition, high process availability.
Tool-free wiring (optional push-in terminals) and optional attachable display for measured value.
Suitable for use in explosive atmospheres (hazardous areas) with appropriate versions/certifications.
