Product Description

What this part is:
The R. Stahl 9146/10-11-12 is a single-channel frequency transmitter from the ISpac Series 9146 Ex i isolators. It converts an intrinsically safe binary input from a hazardous-area sensor into a 0/4–20 mA signal proportional to frequency, with two limit value contacts and a pulse output. Typical duty is speed monitoring of fans, centrifuges, blades and stirrers in hazardous areas.

Decoding the designation:
9146 — R. Stahl Series 9146 frequency transmitter, Ex i field circuit.

10-11-12 — the 1-channel version with 0/4–20 mA output, 2 NO/NC limit value contacts and one selectable NO impulse output.

What these specs mean in practice:
Channels: 1. Input Signal: NAMUR per EN 60947-5-6. Input Frequency: 0.001 to 20,000 Hz. Output Signal: 0/4 to 20 mA, configurable. Connectable Load: 0 to 600 Ω. Limit Value Contacts: 2 NO (electronic), ±30 V, 50 mA. Pulse Output: 0 to 5 kHz, dividing ratio 1:1 to 1:20,000. Auxiliary Power: 24 V DC nominal, 18 to 31.2 V range. Nominal Current: 55 mA. Power Consumption: 1.32 W. Accuracy: 0.1 % typical. Parameterisation: ISpac Wizard software.

Explosion Protection: ATEX II 3 (1) G Ex nAc nCc [ia] IIC T4; II (1) D [Ex ia] IIIC; IECEx Ex nA nC [ia Ga] IIC T4 Gc. Installation: Zone 2, Division 2 and safe area, with the Ex i field circuit reaching Zone 0 and Division 1.

Mounting data:
Mounting: DIN rail NS35/15 or NS35/7.5, or pac-Carrier. Width: 17.6 mm. Enclosure: IP30, PA 6.6. Terminals: IP20. Ambient Temperature: -40 to +70 °C single device; -20 to +60 °C group assembly. Item Weight: approx. 160 g.

Interchange guidance:
Current order codes add a terminal suffix: 9146/10-11-12s for screw terminals, 9146/10-11-12k for spring clamp terminals. The 2-channel 9146/20-11-11 has no limit contacts or pulse output.
