Introduction

The CIS-202 Control Interface provides four Relay / Contact Closures. The maximum
ratings are:

0.6A 125V AC

0.6A 110V DC

2.0A 30V D C

The CIS-202 can be used either alone or in any combination of CIS-200 series devices, up
to a maximum of 16. Since RS232 is a single-ended data transmission method (between
only one transmitter and one receiver) only one CIS-200 can be used (since it is full two
way), but by utilizing a buffered ‘loop out’ from each unit, up to 15 additional one way
devices (CIS-201 and/or CIS-202) can reside on the the same bus. Each one way device
has its own ID number (1-15), selected by its front panel dip-switch. ID number 0 is
reserved for the CIS-200.
