ADLINK ACL-7125 provides 8-CH relay outputs and 8-CH isolated digital inputs. Four of the relays are
SPDT (Form C) and four are SPST (Form A), which are suitable for device connection with ON/OFF control.
The status of each relay output is represented by an on-board LED. When the relay is energized, its
corresponding LED will turn ON, otherwise it is OFF. All of the digital input channels are non-polarity and
optically isolated. Users can set for each digital input by using RC filter or not. The device is suitable for
collecting digital inputs in noisy environments.
