NOTE: The LEDs positioned at the top of the PLC, which go from led 0 to 9 refer to both inputs and outputs.
Ref. 013002000100 Rev.0: 0-09-2020 Jumper configuration General jumper configuration The 10 I/Os Digital Module provide 10 digital pins that can act as both input and output. However, they can only be working as one option at a time, so if their function is wished to be changed the jumpers must be adjusted.

Ref. 013002000100 Rev.0: 0-09-2020 Warning! Outputs: if the pin is working as output, its jumper of Zone 3 must be connected as the 3.3 – 24 V option. Inputs: if the pin is working as input, DO NOT connect the jumper if you are using a power supply voltage of 230V as it will damage the device and could burn it.

Ref. 013002000100 Rev.0: 0-09-2020 Provide adequate clearance for cooling and wiring 10 I/Os Digital Module. Is designed for natural convection cooling. For proper cooling, you must provide a clearance of at least 25 cm above and below the devices. Also, allow at least 25 cm of depth between the front of the modules and the inside of the enclosure.
Page 36
Ref. 013002000100 Rev.0: 0-09-2020 - Disconnect the external power supply of the system (on all phases) before connecting or disconnecting a module. Failure to observe this precaution may cause faults or malfunctions of the module. - Tighten the screws of the terminal ports and the screws of the connectors within the prescribed tightening torque.
