Technical Description 

The 

PLC-16.PCI

 provides two parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. 

Port A is an input port interfaced to optically isolated inputs, while port C is the relay output port. 

Features 

Digital Inputs 

 

Number of inputs: Eight. 

 

Type: Non-polarized, optically isolated from each other and from the computer. 

 

Voltage Range: 5 to 24V DC or AC. 

Relay Outputs 

 

Number of outputs: Eight. 

 

Contact Rating: 2A carry current, bifurcated, gold clad, silver palladium. 

 

Contact Arrangement:  SPDT (Single Pole Double Throw) Form C. 

 

Contact Resistance: Initial 100 milliohms maximum. 

 

Contact Life: mechanical: 10 million operations minimum. 

 

Contact Life: electrical: 5 million operations minimum at full load. 

 

Operating Time: 2 milliseconds maximum. 

 

Release Time: 1 milliseconds maximum.
