Digital I/O and Relays 

Use the provided terminal block connectors and the connector 
diagram in Figure 5 to wire Digital I/O and Relays to the iServer 2. 

The DI connections (DI2+, DI2-, DI1+, DI1-) accept a 5 V (TTL) input. 

The DO connections (DO+, DO-) require an external voltage and 
can support up to 0.5 amps at 60 V DC. 

The Relays (R2, R1) can support a load of up to 1 amp at 30 V DC. 

Important:

 

When wiring the included terminal block 

connectors to access the digital I/O, alarms, or 
relays, it is recommended that users ground the unit 
by connecting a wire to the chassis ground of the 
connectors shown in Figure 9. 

Below is an example of an LED Circuit connected to the Digital Inputs and outputs. 

Figure 10: iServer 2 sample LED circuit with digital input and output

 

Further configuration regarding Normally Open/Normally Closed Initial State or Triggers can be 
completed in the iServer 2 web UI. For more information, refer to sections 6.5.2 Relay 1 and Relay 2 
or 6.5.4 Digital I/O.
