ADLINK ACL-7225 provides 16-CH relay outputs and 16-CH isolated digital
inputs. Eight of the relays are SPDT (Form C) and eight 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.
