ExLine – Intrinsically Safe Signal Converter

Key features

EXL-IM-9182: converts the signal of a passive probe (Pt100/Pt500/Pt1000/Ni100/thermocouple or 0–1000 Ω resistance transmitter for humidity probes) to 0/4–20 mA; the TFFR-2G probe (temperature + humidity) requires 2 channels
EXL-IR-9170: converts a passive binary/contact signal to a relay or electronic (transistor) output in the safe area
Galvanic isolation between the intrinsically safe input, output and power supply
1 or 2 channels depending on the order code
DIN rail mounting (NS35), compact width ~17.6 mm
Selected versions suitable for use up to SIL 2 according to IEC 61508 (FMEDA assessment)

Applications

Temperature transmission from Ex zones Binary status transmission from Ex zones PLC/DCS integration

ExLine modules are rebranded ISpac units from R. STAHL – functionally, they act as a galvanic isolator between the ExSens probe in the Ex zone and the control system in the safe area.

Functional safety

Selected versions suitable for use up to SIL 2 (IEC 61508, FMEDA assessment)

ExLine consists of two module types depending on the type of signal transmitted from the ExSens probe. The module is located in the safe area or in Zone 2 (versions powered by 120–230 V AC in the safe area only), the probe in Zone 1 or 2 (…2G3D types also in Zone 22).
