MeloAuto-Trusted PLC & DCS Parts Supplier
The Schneider 140XSM00200 Modicon Quantum Discrete Input Simulator provides manual testing for Quantum I/O modules. This simulator generates discrete 24 VDC signals for input channel verification. You will find it in commissioning and troubleshooting applications for PLC systems. It replaces field sensors during logic testing and simulation. Therefore, this unit reduces commissioning time and simplifies fault finding.
The Schneider 140XSM00200 Modicon Quantum Discrete Input Simulator measures 85 mm in height and 65 mm in width. Its depth reaches 40 mm for direct module mounting. The unit weighs approximately 0.25 kilograms. It contains 32 manual toggle switches for input simulation. Each switch connects to a 24 VDC supply when engaged. Additionally, you get a 40-pin IDC header for module connection.

Internal Architecture and Energy Storage
The Schneider 140XSM00200 Modicon Quantum Discrete Input Simulator stores absolutely no electrical energy internally. It contains no capacitors or electronic components. Thirty-two toggle switches connect directly to a 40-pin IDC header through copper traces. When you flip a switch UP, it connects the corresponding pin to +24 VDC. When you flip a switch DOWN, it connects the pin to 0 VDC. The simulator requires an external 24 VDC power supply for operation. An LED on the front panel indicates proper supply voltage. A 40-pin IDC female header plugs directly into the Quantum I/O module. The plastic housing provides protection against accidental contact.
Connection Interfaces and Wiring Details
You will find a 40-pin IDC female header on the rear of the simulator. Connect this header directly to the front of a Quantum I/O module. The Schneider 140XSM00200 Modicon Quantum Discrete Input Simulator requires an external 24 VDC power supply. Connect the positive wire to the +24V terminal on the side. Connect the negative wire to the 0V terminal. A red PWR LED lights up when the simulator receives 24 VDC. Each toggle switch corresponds to one input channel. Flip switch 1 UP to simulate a “1” signal on channel 1. Flip switch 1 DOWN to simulate a “0” signal on channel 1. The simulator has no field wiring connections at all.
Installation and Operation Steps
You power off the PLC system before connecting this simulator. First, align the 40-pin header with the I/O module front connector. Then, press the simulator firmly until it snaps into place. Connect the 24 VDC power wires to the side terminals. The Schneider 140XSM00200 Modicon Quantum Discrete Input Simulator consumes 25 mA from the supply. Power on the PLC system and observe the simulator’s PWR LED. Flip each toggle switch to the UP position one at a time. Verify that the corresponding input channel shows a “1” in the PLC software. Flip each switch DOWN and verify the input shows a “0”. Remove the simulator and reconnect field wiring after testing. Store the simulator in a clean, dry location when not in use.
