Description:

The EPR16-RE and EPR16-OK extension cards enhance and amplify the digital outputs of the EPR16, EPR16S, and EPC16 controllers. Each card provides specific benefits depending on the application requirements, such as relay or transistor outputs and built-in protections against short circuits or overheating.

Relay Card EPR16-RE:

• 16 digital relay outputs
• Watch-Dog output as a potential-free relay contact
• All relay contacts feature 250V-varistor protection
• Two galvanically isolated contact blocks:
- Outputs 1–8 and Watch-Dog
- Outputs 9–16

• Supports operation with different voltages

Power Optocoupler Card EPR16-OK:

• 16 electronic transistor outputs (short-circuit proof)
• Watch-Dog output as a 0.5A transistor output
• Galvanic isolation via optocouplers
• Protection against overheating and short circuits:
- Automatic restart after overload removal

• Two contact blocks with common connections:
- Outputs 1–8 and Watch-Dog
- Outputs 9–16

• Maximum continuous current per output: 0.5A
• External operating voltage: DC 10–30V

Installation and Connections:

• Direct connection to the OUTPUT socket of EPR16, EPR16S, or EPC16 controllers
• Secured with supplied screws to designated mounting bolts
• Relay power supplied by the controller
• Important Notes:
- Ensure proper seating of the detachable terminal block connectors
- Inductive loads (e.g., solenoids, contactors) require protective circuits (RC network or varistor)


Technical Specifications:

• Relay Card EPR16-RE:
- Galvanically isolated contact blocks
