- Wide Temperature Range: Reliable operation from -20°C to +60°C covers most industrial cabinet environments without additional climate control
System Architecture & Signal Flow
The P27000-H1 operates as a transparent signal bridge within the control loop architecture:
- Field Input Stage: Accepts raw sensor signal (mA, mV, Ω, or thermocouple EMF) with input protection against transients and reverse polarity
- Galvanic Isolation Barrier: Transformer-based 3-way isolation block eliminates common-mode interference and ground potential differences between field and control levels
- Signal Processing Core: High-resolution A/D and D/A conversion with linearization algorithms for thermocouple and RTD inputs; configurable scaling and offset
- Output Stage: Drives standard 0/4–20 mA or 0–10 V signals into PLC/DCS analog input cards with ≤ 0.1% accuracy
- Diagnostics: LED status indication for power, signal validity, and fault conditions; optional HART pass-through on select variants
Compatible control system interfaces: Siemens S7/S5, ABB 800xA, Honeywell Experion, Yokogawa CENTUM, Emerson DeltaV, Rockwell ControlLogix, Schneider Modicon, and all standard 4–20 mA analog input cards.

Technical FAQ
Q: Can the P27000-H1 replace a Knick P11000 or P21000 in an existing installation?
A: The P27000-H1 is the successor platform to the P11000/P21000 series with backward-compatible signal ranges. Terminal assignments may differ — consult the wiring diagram before direct substitution.
Q: Is the P27000-H1 approved for use in ATEX Zone 1 hazardous areas?
A: Yes, with the appropriate Ex ia certification variant. Confirm the full model suffix includes the ATEX designation before installation in classified areas.
Q: What is the maximum loop resistance for 4–20 mA output?
A: The output stage drives up to 750 Ω load at 24 V DC supply — sufficient for most PLC analog input cards and HART communicators in the loop.
Q: Can multiple P27000-H1 units share a single 24 V DC power rail?
A: Yes. Each module draws ≤ 2 W; a standard 10 A / 24 V DC PSU supports up to 120 modules on a shared bus with appropriate fusing per segment.
Q: How do I configure the input/output range without a PC?
A: Front-panel DIP switches allow basic range selection. For full parameter access including linearization tables and scaling, Knick KonfigSet software (free download) connected via the front-panel USB/RS-232 port is required.
Q: What is the typical delivery lead time from Konmask?
A: In-stock units ship within 1–3 business days. For out-of-stock items, lead time is 2–6 weeks depending on factory availability. Contact us for real-time stock status.
