Schneider 180 CPX 120 00 Terminal CPX

The Schneider 180 CPX 120 00 serves as a passive terminal block for Modicon TSX Micro systems. This CPX terminal connects field devices to discrete I/O modules. You will find it in compact control cabinets with limited wiring space. It provides 20 screw-type connections for sensors and actuators. Therefore, this unit simplifies field wiring and maintenance tasks.

This terminal measures 90 mm in height and 70 mm in width. Its depth reaches 55 mm for DIN rail mounting. The unit weighs approximately 0.19 kilograms. It contains no active electronic components at all. Twenty screw terminals line up in two rows of ten. Additionally, you get a 20-pin IDC header for module connection.

Key Technical Specifications

Internal Architecture and Energy Storage

The Schneider 180 CPX 120 00 stores absolutely no electrical energy internally. It contains no capacitors, batteries, or semiconductor devices. Twenty screw terminals connect directly to a 20-pin IDC header. Each terminal has a direct copper trace path to its corresponding header pin. A high-temperature polyamide housing protects all connections from dust. The terminal accepts solid or stranded copper wire without issues. You get a built-in ground terminal for shield drain wires. Each terminal has a test point for probe access.

Connection Interfaces and Wiring Details

You will find 20 screw terminals arranged in two horizontal rows. Each terminal accepts 24 to 16 AWG copper wire. Use a 3mm flathead screwdriver to loosen and tighten each screw. Strip 7 mm of insulation from each wire before insertion. Then, insert the bare copper into the square terminal opening. Tighten the screw to 0.5 Nm of torque maximum. The Schneider 180 CPX 120 00 includes a 20-pin IDC female header on top. This header connects directly to a TSX Micro I/O module. Align the header pins carefully before pressing the module down. A polarizing key prevents incorrect insertion orientation.

Installation and Mounting Steps

You mount this terminal onto standard 35 mm DIN rail. First, hook the top clip onto the rail edge securely. Then, press the bottom toward the rail until it snaps into place. Slide the terminal along the rail for easy panel layout. Connect all field wiring before snapping on the I/O module. Label each terminal with its corresponding channel number clearly. The Schneider 180 CPX 120 00 requires no external power supply at all. It simply routes signals between field devices and the I/O module. For high-vibration areas, add end stops on both rail ends. Snap the chosen TSX Micro module onto the terminal until the latch locks. Verify each connection with a continuity tester before power-up.
