I/O Systems - S800 I/ODI828

The DI828 is an 16 channel 120 V a.c/d.c. digital input module for the S800 I/O. The module has 16 digital inputs. The AC input voltage range is 77 - 130 V and the input current is 8.5 mA at 120V AC. The DC input voltage range is 75 - 130 V and the input current is 2.4 mA at 120V DC. The inputs are individually isolated.

Every input channel consists of current limiting components, EMC protection components, input state indication LED, optical isolation barrier and an analog filter. Channel 1 can be used as voltage supervision input for channels 2 - 8. Channel 16 can be used as voltage supervision input for channels 9 - 15.

If the voltage supervision is used and the voltage connected to channel 1 or 16 disappears, the channel error will be set for the channels and the Warning LED turns on. The error signal can be read from the ModuleBus.
