2. GENERAL DESCRIPTION
The SX-2000CI Control Input Unit is equipped with 32 control input channels, and the SX-2000CO Control
Output Unit with 32 control output channels, allowing various operations to be performed by connecting
external equipment.
One each of the SX-2000CI and SX-2000CO must be used in combination. Connecting the CI/CO link data
terminals of each unit to one another permits the contact data of multiple channels to be transmitted to the
remote locations with simple wiring.
The front-mounted indicators of each unit show the control input status or control output status.
The SX-2000CI and SX-2000CO are 1U-size* units that can be mounted in an EIA equipment rack. It has 2
power supply inputs, one of which can be connected to a backup power source to protect against power
failures. The SX-2000CI has a function to supply a stabilized 24 V DC.
Priority control of the control input can be performed by making settings at the SX-2000CI.
*1U size = 44.5 mm (standard size)
