Input Wiring Options 

There are six input wiring options: 

 

Normally Open 

 

Normally Closed 

 

Normally Open Supervised with one or two resistors 

 

Normally Closed Supervised with one or two resistors 

 

Normally Open Switch

Figure 3 shows the normally open input connection. 

Figure 3: Normally Open Input 

 

Figure 4 shows the normally closed input connection. 

Figure 4: Normally Closed Inputs 

 

Figure 5 shows the normally open supervised input connection with 
single resistor. 

Figure 5: Normally Open Supervised Inputs with Single Resistor 

 

Normally Open Supervised inputs with one resistor must be connected 

with an 8.2K resistor in parallel to the input switch contacts. 

 

Always wire resistors on the input switch and not on the 
terminal block. 

Figure 6 shows the normally open supervised input connection with 

double resistor. 

Figure 6: Normally Open Supervised Inputs with Double Resistor 

 

Normally Open Supervised inputs with two resistors must be connected 

with an 8.2K resistor in parallel and a 2.2K resistor in series to the 
input switch contacts. 
Figure 7 shows the normally closed supervised input connection with 

single resistor. 

Figure 7: Normally Closed Supervised Input with Single Resistor 

 

Normally Closed Supervised inputs with a single resistor must be 

connected with a 2.2K resistor in series to the input switch contacts. 
Figure 8 shows the normally closed supervised input connection with 

double resistor. 

Figure 8: Normally Closed Supervised Input with Double Resistors 

 

Normally Closed Supervised inputs with two resistors must be 
connected with an 8.2K resistor in parallel and a 2.2K resistor in series 

to the input switch contacts.
