The Siemens 39VIMNBN is a high‑density 16‑channel Voltage Input Module (VIM) engineered for the Siemens APACS+ distributed control system (DCS). This 39VIMNBN module features individually configurable channels for thermocouple or voltage inputs, providing exceptional flexibility for process data acquisition. Each channel includes advanced digital filtering, adjustable step response times, and open‑circuit detection to ensure accurate signal measurement in industrial environments. Fully isolated channel‑to‑channel, the 39VIMNBN interfaces directly with the control module’s IOBUS, making it a robust, high‑precision solution for legacy system upgrades or new automation projects requiring flexible analog input capabilities.
Process temperature monitoring using thermocouples (types B, E, J, K, R, S, T, N1, N2)
Voltage signal measurement for pressure, flow, level, or position transducers
Legacy system modernization and APACS+ DCS I/O expansion
Critical data acquisition requiring channel‑to‑channel electrical isolation
16 Universal Input Channels – Each channel independently configurable for thermocouple or voltage input.
Wide Thermocouple Support – Compatible with B, E, J, K, N1, N2, R, S, T types, covering most industrial temperature ranges.
Adjustable Digital Filtering – First‑order lag filter with time constants from 0.0159 to 159.0 seconds reduces electrical noise.
Full Channel Isolation – Per‑channel isolation from CPU, IOBUS, ground, and other channels prevents field faults from propagating.
Comprehensive Engineering Units – Select from over 100 engineering units, simplifying direct process value reading.
Redundancy Ready – SharedTC parameter for dual VIM configurations with shared thermocouple wiring.
Flexible Scaling – MinScale and MaxScale parameters allow custom scaling of raw voltage to process values.
Signal Conditioning – Converts thermocouple millivolt signals or analog voltage inputs (e.g., 1‑5V, 0‑10V, ±10V) into calibrated, scaled REAL (floating‑point) engineering units.
Noise Rejection – Built‑in 50/60 Hz notch filter and programmable first‑order digital filter improve signal integrity in electrically noisy environments.
Open‑Circuit Detection – Configurable burnout detection (UP/DOWN) identifies broken thermocouple wires or signal loss.
Channel‑to‑Channel Isolation – Electrical isolation prevents ground loops and fault propagation, protecting control system backplane.
Redundant Operation – SharedTC softlist parameter enables proper configuration for shared thermocouple wiring in redundant VIM systems.
Q1: What control system is the 39VIMNBN compatible with?
A1: The 39VIMNBN is designed for the Siemens APACS+ distributed control system, interfacing directly with the control module’s IOBUS.
Q2: Can the 39VIMNBN mix thermocouple and voltage inputs on the same module?
A2: Yes, the 39VIMNBN allows each of its 16 channels to be individually configured as either a thermocouple or a voltage input, providing maximum flexibility.
Q3: What is the purpose of the “SharedTC” parameter?
A3: In redundant configurations where a single thermocouple is wired to both a primary and backup VIM, set SharedTC to YES for proper operation; otherwise, keep the default NO.
Q4: How does the 39VIMNBN handle open thermocouple circuits?
A4: The 39VIMNBN provides configurable burnout detection. It can be set to return the maximum (UP) or minimum (DOWN) scale value, or disabled, depending on the application.
Q5: How does the digital filter work on the 39VIMNBN?
A5: The 39VIMNBN applies a first‑order lag digital filter to thermocouple inputs. You can adjust the time constant from 0.0159 to 159.0 seconds to reduce electrical noise; setting it to 0.0 disables the filter.
