ABB DI880 High Integrity Digital Input Module product description
ABB DI880 High Integrity Digital Input Module product description
The DI880 is a 16 channel 24 V d.c. digital input module for single or redundant configuration. The input voltage range is 18 to 30 V d.c. and the input current is 7 mA at 24 V d.c.
Each input channel consists of current limiting components, EMC protection components, input state indication LED and optical isolation barrier.
There is one current limited transducer power output per input. The Sequence of Event function (SOE) can collect events with a resolution of 1 ms. The event queue can contain up to 512 x 16 events. The function include a Shutter filter for suppression of unwanted events.
The SOE function can report the following status in the event message – Channel value, Queue full, Synchronization jitter, Uncertain time, Shutter filter active and Channel error.
The input signals can be digitally filtered. The filter is selectable from 0 to 127 ms.
This means that pulses shorter than the filter time will be filtered out and pulses longer than specified will get through the filter.
Six different types of MTUs can be used for single applications. The Extended MTU (for example TU830/TU833) enables three wire connection to the sensors without additional terminals. The Compact MTU (for example TU810, TU814) has terminals for process voltage supervision inputs, but requires external terminals for distribution of process power supply to the sensors. The TU818 Compact MTU provides connection to 2-wire sensors without external marshaling. The TU812 Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.
For redundant applications there are three types of MTUs, TU842/TU852 for mounting on a horizontal DIN rail and TU843 for mounting on a vertical DIN rail.
Shielded field cables are required for process connections (over all shield is sufficient if a multi core cable contains sorted signal types). It is recommended to feed all sensors connected to DI880 from the current limited sensor power supplies that are supplied by DI880, to fulfill this TU830, TU833, TU842, TU843 or TU852 should be used. If single Compact MTUs (TU810, TU812, TU814 or TU818) are used, refer to the Technical Description 3BSE050455.
