Vibro-Meter 200-560-000-114 IOC4T Input/output Card

Vibro - Meter 200 - 560 - 000 - 114 IOC4T input/output card is the signal interface card of MPC4 mechanical protection card in VM600 series. Here is its detailed introduction:

Basic function: It is the signal interface of MPC4 mechanical protection card, with 4 dynamic signal input channels and 2 tachometer input channels, supporting differential signal input, all channels can be configured independently, which can meet the measurement needs of various mechanical protection applications.

Installation and connection: Installed at the rear of VM600 rack, directly connected to the rack backplane through two connectors. Each IOC4T card is associated with the corresponding MPC4 card, directly installed behind the MPC4 card in VM600 rack (ABE04x or ABE056), operates in slave mode, and communicates with MPC4 using industrial package (IP) interface through connector P2.

Terminals and Signal Transmission: The front panel contains terminal strip connectors for connecting transmission cables from the measurement chain (sensors and/or signal conditioners), and for inputting all signals from any external control system, and outputting all signals to any external control system, with a total of 48 terminals.

Signal Processing and Output: The raw dynamic (vibration) and velocity signals from the sensors are connected to the MPC4, and the signals are processed and transmitted back to the IOC4T and provided on the terminal strip on its front panel. The four on-board digital-to-analog converters (DACs) on the card provide calibrated signal outputs in the range of 0 to 10V for the dynamic signals, and four on-board voltage-to-current converters provide current output signals in the range of 4 to 20mA (jumper selectable).

Relay and Alarm Functionality: Four local relays are included and can be used under software control for any specific alarm signal, such as signaling an MPC4 fault or a problem detected by the common alarms (sensor normal, alarm and danger). In addition, 32 digital signals representing alarms are transmitted to the rack backplane and can be used by the optional RLC16 relay card and/or IRC4 intelligent relay card (jumper optional) installed in the rack.

Protection function: Protect all inputs and outputs from electromagnetic interference (EMI) and signal surges, in compliance with electromagnetic compatibility (EMC) standards.

Other features: Support real-time card insertion and removal (hot swap) function, which is convenient for card replacement or maintenance while the system is running. It has alarm reset (AR), dangerous bypass (DB) and trip multiplication (TM) control inputs, and different functions can be achieved by closing the contacts between the corresponding inputs. Available in "standard" and "independent circuit" versions.
