CM9760-REL Relay Interface Unit
CONTROLS UP TO 64 RELAY CONTACT OUTPUTS PER UNIT
Product Features
• Each Unit Provides up to 64 Single-Pole, Single-Throw (SPST)
Contact Outputs for Operating Different Peripheral Equipment
• Relay Output Contacts Can Be Configured for Normally Open (Factory
Default) or Normally Closed Operation
• Memory Feature Allows Relay Groups to Retain or Hold Their
Contact Position in the Event of a Power Failure or Front Panel Reset
• Multiple Units Can Be Daisy-Chained to Extend the Number of Relay
Contact Outputs Controlled from a Single Port on the CC1 (More Than
5,000 Relay Outputs Can Be Confi
gured)
• The Relay Unit Can Be Remotely Placed up to 4,000 Feet
(1,219 meters) from the Controller (RS-422 Operation)
The CM9760-REL relay interface unit is an optional accessory for
System 9700 Series matrix switchers. The unit provides dry contact
switching for direct or automatic control of peripheral equipment.
The unit connects to any RS-422 COM port on the rear of the
CM9700-CC1.
The basic function of the relay unit is to allow the user to control
various peripheral equipment through relay contacts. Each relay unit
processes and executes commands only with addresses that match
that of the RELs (frame address). When a relay unit receives a
command with an inappropriate address, it passes it on to the next
unit (if applicable) through its output port.
The front of the relay interface unit has three 10-position DIP
switches that configure the communication parameters for the unit
as well as setting the parameters for relay contact output operation.
The front also has a red data LED that flashes when the first valid
command is received.
The relay unit mounts in a standard 19-inch (48.26 cm) rack and
occupies only 1 RU (1.75 inches or 4.45 cm) of rack space. For
remote operation, the wiring from the relay unit to the system
controller should not exceed 4,000 feet (1,219 m).
Daisy-chaining is required when more than 64 relays are needed.
Each unit must be configured to have a unique frame address.
Daisy-chain configurations can be used whether relay units are
situated locally, remotely, or as a combination of the two.
