2110 Monitoring System

Measures vibration, speed, temperature and other process variables in any combination

The 2110 provides around-the-clock monitoring of machinery and processing equipment and warns operating personnel when predetermined limits have been exceeded. Individual bar graph displays give continuous indications of each channel, allowing the operator to view vibration, speed or other process variable levels at a glance. LEDs on the individual modules energize to indicate alarm, trip and pick-up status.

The unit features high-density operation, up to 248 channels of process variable monitoring. Modular construction ensures economical system expansion, without the need for field programming or returning the system to the factory for modification. The system combines the proven reliability of analog signal conditioning with the ease of use and dynamic display capabilities of a microprocessor-based system.

The 2110 comes with another valuable feature – Vitec applications support. Our experienced Application Engineers are available to help you custom tailor a system to fit your individual needs or simply answer your vibration questions. A system is only as good as the company that backs it.

Each 2110 Monitoring System is custom-configured to meet the Customer’s exact requirements. Please contact Vitec to have one of our Application Engineers help configure your system and supply a quotation.

Mounting Rack


The first rack in each system is referred to as the “Master” rack, as it will typically house the control module/power supply and up to six additional monitoring modules. Additional mounting racks are referred to as Slave racks, and are capable of housing up to eight monitoring modules or specialty modules, in any combination.

Control and Power Supply Module


The 2110 Control Module/Power Supply is a double-wide module located in the first two positions in the Master rack. This module is capable of operating up to 248 channels of continuous monitoring. The keypad allows for system interrogation, providing such features as monitor point ID and digital display of measured values.
LED indications for pickup malfunction, alarm and trip conditions, and first out are located on the front panel, providing the operator a quick visual indication of the status of the channel being interrogated. A buffered AC signal is available at the BNC connector, allowing analyzers or other devices to be interfaced easily.
By selecting a channel via the keypad, the corresponding AC signal is connected to the output jack. Channels can be selected either by the Next or Previous keys, or by the lettered/numbered keys.

Signal Conditioning Module


High-Density Monitoring Modules
Plug-in modules with bargraph displays have continuous signal conditioning for up to four channels of input per 2″ wide module.

In addition to displaying the level of the measured channel, the bargraph display indicates the alarm and trip setpoint for each of the channels with blinking segments in the bar graph. Monitoring points which require four setpoints use two module channels per individual input. In general, there are five different types of signal conditioning modules.

Type 53265-2 modules monitor four separate transducers, with one positive Alarm and one positive Trip setpoint per transducer.

Type 56265-3 modules monitor two separate transducers with one positive and one negative Alarm and Trip setpoint per transducer.

Type 53265-5 modules have the same setpoint configuration as the 53265-3 modules, but utilize a dual-voting system for each point of monitoring.

Type 53265-6 modules have channels A & B configured per Type 53265-2 and channels C & D configured per Type 53262-3.

Type 53265-7 modules monitor four separate transducers with one negative Alarm and one positive Trip setpoint per channel.

Other modules can be custom tailored to specific application requirements

Digital Speed Module


Digital Speed Module

Input: Non-Contact Probe

Analog Output: 0-5V (standard) or 4-20mA DC (optional)

General: The Digital Speed Module provides a single channel of speed monitoring. Digital circuitry is used to allow monitoring accuracies of ± 1 RPM.

Display: A digital display provides a continuous indication of speed in RPM.

Setpoints: Two individually adjustable setpoints are available for alarm and trip purposes. Moving the toggle switch to the alarm or trip position displays the alarm or trip setpoint on the digital display.

Module size: 2″ wide x 6-7/8″ high, uses one module space.

Relay Module


Relay Module

Each Relay Module contains six (6) relays to be used for alarm or trip purposes.

Rating: Each relay is an SPDT relay rated 5A @ 150V DC non-inductive load. However, the 6 relays can also be configured as three (3) DPDT relays.

Time Delay: Each relay has an individual, front panel accessible time delay adjustment that can be adjusted from one (1) to fifteen (15) seconds.

Relay Inhibit: The relays can be inhibited individually by a switch behind the front panel nameplate. The entire module can also be inhibited by a customer-supplied switch closure connected to the rear terminals.

Relay State: Each relay can be set individually to be latching or non-latching, failsafe or non- failsafe. Each relay provides a common, NO and NC contact connection on the rear terminal strip.

Module Size: 2″ wide x 6-7/8″ high, uses one module space.

Also available with indicating LEDs.

Key Phase Module


Key Phase Module

Input: Non-contact probes

Analog Output: None

Display: None. This is a special four-channel module that provides signal conditioning for key phase application. The module provides four BNC jacks that provide a pulsed output for each of up to four different key phase channels.

Operation: The key phase module provides a 10-volt square wave output signal upon sensing of a slot in the shaft. The circuitry of this module exceeds the API specifications by allowing the input signal circuit to be adjusted for various depths of slots.

Module Size: 2″ wide x 6-7/8″high, uses one module space.

System Flexibility


The high-density monitoring modules are built using simple, reliable components: the Universal Board with four-channel LCD display and dual signal conditioning cards. Measured values are continuously displayed on the four-channel LCD. Setpoint levels appear as blinking segments, on each bar graph display. Modules are custom-tailored to fit your precise requirements – there is no operator set-up or programming necessary.
Across the top of each module is a row of color-coded LEDs which indicate the status of that module. If an alarm or trip level has been exceeded, the appropriate LED will energize. Located below each bar graph is an “OK”, “A” and “T” that indicates that channel’s status within the module.
Behind each engraved name tag is a row of adjustable pots. The pots allow the operator to independently adjust the alarm and trip setpoint levels for each channel. Setpoint levels are displayed digitally on the Control Module display, and as a blinking segments on that particular channel’s bar graph.
