Honeywell UDC2500 ユーザーズマニュアル

To determine the appropriate diagrams for wiring your controller, refer to the model 
number interpretation in this section. The model number of the controller is on the 
outside of the case. 

Instruments with multiple outputs can be configured to perform a variety of output types 
and alarms.  For example, an instrument with one current output and two relays can be 
configured to provide any one of the following: 

1) Current Simplex with two alarm relays 

2) Current Duplex 100% with two alarm relays 

3) Time Simplex with one alarm relay 

4) Time Duplex with no alarm relays 

5) Three Position Step Control with no alarm relays 

These selections may all be made via the keyboard and by wiring to the appropriate 
output terminals; there are no internal jumpers or switches to change.  This flexibility 
allows a customer to stock a single instrument which is able to handle a variety of 
applications.   

 

Table 2-6 shows what control types and alarms are available based upon the installed 
outputs.  In this table, when Duplex Control and Reverse Action are configured: 

Output 1 is HEAT and Output 2 is COOL. 

 

In Table 2-6 when Three Position Step Control is configured: 

Output 1 is OPEN and Output 2 is CLOSE. 

 

In Table 2-6 the Output 1/2 option Single Relay can be any of the following selections:  
Electro-Mechanical Relay, Solid-State Relay or Open Collector Output.
