ABB IMDSM04 Pulse Input Slave Module

ABB IMDSM04 Pulse Input Slave Module

FEATURES

The DSM is an active interface device that supplies data to the Infi 90 Multi-Function Processor (MFP). The DSM conditions, converts and processes pulse inputs such as low level amplitude pulses, sinewaves, logic level pulses, or contact closures into digital signals. Applications for the DSM include: turbine flowmeters, tachometers,Wattmeters, proximity sensors and counters. One slave provides eight independent pulse or frequency inputs to the master module. The input signals are optically isolated. The DSM also Interfaces to existing Network 90 Multi-Function Controllers (MFCs).

The modular design of the DSM, as with all Infi 90 modules, allows for flexibility when you are creating a process management system strategy. It can bring eight separate pulse signals in three voltage ranges. Two ranges are 4 to 6 VDC and 21.6 to 27 VDC (the 21.6 to 27 VDC range allows connection of dry contact inputs). The third range is input to the preamplifiers on channels 1 and 2 (for low level pulse inputs between 50 millivolts and 10 Volts peak to peak). The DSM connects inputs to the Infi 90 system without separate converters.

You can select individual voltage and response time with jumpers on the module to configure each input. Selectable response times (fast or slow) allow the Infi 90 system to compensate for process field device debounce time.

The slave provides 16 bit resolution in the input channels for frequencies up to 50 kilohertz. It makes high resolution measurements of low frequency signals at selected rates for periods between 20 microseconds and 655 x 103 seconds. The slave can count the number of rising or falling edges of input signals and measure the time between the pulse edges.
