ABB DI803 3BSE022362R1 Digital Input Module

Description

The DI803 is an 8 channel 230 V a.c./d.c. digital input module for theS800 I/O. This module has 8 digital inputs. The a.c. input voltage
range is 164 - 264 volt and the input current is 7.6 mA at 230 V a.c.The d.c. input range is 175 - 275 V and the input current is 1.6 mA at220 V. The inputs are individually isolated. Every input channelconsists of current limiting components, EMC protection components, input state indication LED and optical isolation barrier.

S800 information

S800 I/O provides distributed I/O on PROFIBUS and Advant Fieldbus 100 (AF100). S800 I/O is also used as a communication link to some of ABB’s Drives. With the network definition PROFIBUS, it means the both versions; PROFIBUS-DP and PROFIBUS-DPV1. An I/O station can be configured over the Fieldbus. Typical parameters are signal range, filter time, etc. The status of the modules are indicated by LEDs and also accessible over the fieldbus. Analog values are scaled 0-100% of the signal range. AI/AO modules are scanned every 4th I/O scan cycle. RTD/TC every 10th cycle. Values are transferred cyclically on the fieldbus limited by the fieldbus and the fieldbus master. The Fieldbus Communication Interface is scanning the I/O modules cyclically. The cycle time, 4-108 ms, is dependent on type and number of modules.
