Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Signal range 2 to 22 mA Maximum load The maximum load resistance depends on the supply voltage (U) and must be determined individually for each current loop, see formula and diagram.
- Additional resistances, such as the resistance of the extension cable (per wire ≤0.09 Ω/m), have to be subtracted from the value calculated as shown in the equation.
- load resistance [Ω] Radd Additional resistances such as resistance of evaluating device and/or display unit, cable resistance [Ω] U Supply voltage [V] L Basic length, extension cable [m] Supply voltage 8 to 28 VDC Power consumption ≤ 0.62.
- current consumption: ≥ 2 mA Electrical connection • The supply voltage must match the supply voltage specified on the nameplate.
- RD GNYE BK A0040869 1 8 to 28 VDC 2 4 to 20 mA RD = red BK = black GNYE = green/yellow Connection values Connection classification as per IEC 61010-1: Overvoltage category 1 Pollution level 1 Terminals in the terminal box Three terminals a.
- Commercially available instrument cable Terminals, terminal box: 0.08 to 2.5 mm2 (28 to 14 AWG) Total outer diameter: 6 mm (0.24 in) ±0.2 mm (0.01 in) PA pressure compensation tube: - Outer diameter 2.5 mm (0.1 in) - Internal diameter 1.5.
- Cross-section 2 x 0.22 mm2 + pressure compensation tube Cable resistance Per wire: ≤0.09 Ω/m Residual ripple No impact on the 4 to 20 mA signal to ±5 % residual ripple within the permitted voltage range.
Topics covered by the datasheet
The document includes sections related to:
- Ordering information
Engineering review checklist
- Verify contact current, voltage, contact resistance, insulation and mating-cycle ratings.
- Check the exact keying, pitch, orientation, mating part and mechanical drawing before footprint approval.
- Review assembly force, retention, cable strain relief and environmental exposure for the application.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
