(SELV – EN 60950) and Protective Extra Low Voltage (PELV – EN 60204) guidelines. Protect the controller with a slow-blowing fuse. IMPORTANT The GuardPLC 1600 can draw up to 8A. 0.5A is needed to operate IMPORTANT the controllers. Up to 7.5A can be used to source voltage power for inputs and outputs connected to the 1600. - Page 9 The controller has 20 digital inputs whose status is indicated via LEDs when the controller is in RUN mode. LS+ is a voltage source that provides 24V dc for a group of four dry contact inputs. There are five groups on the GuardPLC 1600. 24V dc Power Supply (—)
- Page 10 GuardPLC™ 1600 Controllers If devices require 24V dc to operate and use the same power source as the GuardPLC, then wire the outputs of the device directly to inputs on the GuardPLC. 24V dc Power Supply (—) (—) 10 11 12 11 12 L+ L+ 24V DC...
- Page 11 GuardPLC™ 1600 Controllers Follow the closed-circuit principle for external wiring when connecting sensors. To create a safe state in the event of a fault, the input signals revert to the de-energized state (0). The “FAULT” LED activates. For more information on input wiring, see the GuardPLC™ System User Manual, publication number 1753-UM001.

GuardPLC™ 1600 Controllers Example: Connecting Actuators to the Outputs Inductive loads can be connected without a protection diode on the load. However, Rockwell Automation strongly recommends that a protection diode be fitted directly to the load to suppress any interference voltage. A 1N4004 diode is recommended. The digital outputs can be pulsed with the safety-related digital inputs of the same device. -
