Description
The DI801 is a 16-channel, 24 V digital input module for the S800 I/O. It features 16 digital inputs with an input voltage range of 18 to 30 V d.c. and an input current of 6 mA at 24 V. The inputs are organized into one isolated group of sixteen channels, with channel sixteen usable for voltage supervision within the group.
Every input channel consists of current-limiting components, EMC protection components, an input state indication LED, and an optical isolation barrier. Channel 16 can serve as a voltage supervision input for channels 1-15. If the voltage connected to channel 16 is lost, the error inputs are activated and the error signal can be read from the ModuleBus. This supervision can be enabled or disabled with the “a” parameter. When the error inputs are disabled, channel 16 can be used as a normal input channel.
The input channels can be digitally filtered with selectable filter times of 2, 4, 8, and 16 ms. Noise pulses shorter than the filter time will be filtered out, while pulses longer than 3, 6, 12, and 24 ms will pass through the filter.
Features
- 16 channels for 24 V d.c. inputs with current sinking.
- 1 isolated group of 16 with voltage supervision.
- Input status indicators.
- Process and power connection via detachable connectors.
