Page 3: Safety Instructions
Safety Instructions This SI unit and this manual contains essential information to prevent possible injury and damage to (users and other people, and property) and to ensure correct handling. Please confirm understanding the meaning of the following messages (signs) before reading the remaining the text, and always follow the instructions. - Page 4 1.The compatibility of pneumatic equipment is the responsibility of the person who designs the pneumatic system or decides its specifications. Since the products specified here are used in various operating conditions, their compatibility with the specific pneumatic system must be based on specifications or after analysis and / or tests to meet your specific requirements.
- Page 5 NOTE ♦Follow the instructions given below when handling reduced-wiring system: Or it will have a risk of being damaged and operating failure. ♦The instructions on selection (installation, wiring, environment of use, adjustment, operation and maintenance) described below must also be followed. ∗Product specifications •The direct-current power supply to combine should be UL authorization power supply.
- Page 6 •Verify the insulation of wiring. Insulation failure (interference with other circuit, poor insulation between terminals and etc.) could introduce excessive voltage or current to the reduced-wiring system or each I/O device and damage them. •Separate power line for solenoid valves from power line for input and control unit. Otherwise wires can be interrupted with noise or induced surge voltage causing malfunction.

Page 9: Mounting/Installation Method
Mounting/Installation method How to install The SI unit is not designed to be a standalone device. Always use with solenoid valves or Output blocks. In addition, if an Input block is not needed, directly connect an endplate to the SI unit (Part number:EX250-EA1, EX250-EA2). -
Page 10: Wiring And Connection
Wiring and connection 1. Connection ControlNet network consists of nodes, taps, trunk cables, drop cables and repeaters. Wiring should be arranged in accordance with ControlNet specifications. Term Definition Network A collection of connected nodes the connection paths between any pair of devices may include repeaters and bridges. - Page 11 Total cable length for segment A segment is comprised of several sections of trunk cable separated by taps. The total cable length of a segment is equal to the sum of all of the trunk-cable sections. The total allowable length of a segment depends upon the number of taps in your segment. There is no minimum trunk-cable section length requirement.
- Page 12 2.Connection example * SMC only provides the SI unit and the power cable. Please refer to other manufactures for additional parts needed. 3. Power supply wiring The power supply connector features two independent electrical circuits, one for the output devices and one for the SI unit / Input blocks.
- Page 13 SW power supply is applied to the sensor connected to the Input block. Since a maximum of approx. 1V voltage may drop in the unit, select a sensor considering the voltage drop. If 24V needs to be supplied by any means, SW power supply voltage should slightly be increased in order to maintain the sensor voltage at 24V with the actual load applied (allowable voltage of SW power supply ranges from 19.2 to 28.8V).
