Manufacturer: Siemens
Series: Analog Input Series
Category: Voltage Input Module (8-Channel)

Physical Dimensions and Weight

The Siemens 39VIMCBN measures 9.5 inches in length. Its width reaches 1.8 inches for single-slot occupancy. The board thickness sits at 5.2 inches including components. This compact design fits into standard industrial racks. The total weight comes to approximately 0.45 kilograms.

Technical Specifications and Channel Configuration

This voltage input module provides eight differential analog channels.  The module samples each channel with 16-bit resolution. Therefore, you get 65,535 discrete steps across the full range. The conversion time reaches 5 milliseconds for all channels.

Signal Conditioning and Noise Filtering

The Siemens 39VIMCBN includes programmable gain amplifiers for each channel. You can set gains of 1, 2, 4, or 8 per channel. The module uses a 50Hz/60Hz digital filter for noise rejection. This filter removes power line interference from your measurements. Consequently, you get clean, stable readings in noisy industrial environments.

Energy Storage and Protection

This voltage input module includes capacitor arrays for transient protection. Each channel stores 0.1 microfarads for voltage spike absorption. The module withstands continuous overvoltage up to ±30V without damage. Additionally, the board features input clamping diodes for ESD protection. These features safeguard the module during wiring errors or surges.

Interface and Connectivity

The Siemens 39VIMCBN uses a 40-pin edge connector for backplane communication. A removable terminal block accepts field wiring for all eight channels. Each channel provides two terminals for signal positive and negative. Eight LED indicators show channel activity and overload status. You can diagnose wiring problems without special tools.

Component Layout and Construction

The Siemens 39VIMCBN contains 125 discrete components on a four-layer PCB. Key parts include eight 16-bit ADC chips and 16 operational amplifiers. An onboard microcontroller manages all conversion and communication tasks. All components meet industrial temperature ratings from -20°C to +60°C. This robust construction ensures reliable operation for many years.

Integration and Compatibility

Use the Siemens 39VIMCBN with any compatible PLC or DCS system. It works alongside standard Siemens analog output modules. This voltage input supports all common industrial communication protocols.
