Frequently Asked Questions (FAQ)

What does "10 inputs / 10 outputs" mean for this module?

It has 10 points to connect sensors (like push buttons or limit switches) and 10 points to connect output devices (like motors or lights). The TSX1722028 can monitor and control 10 different actions.

Can the relay outputs switch both AC and DC loads?

Yes, the electromechanical relay outputs are versatile. They can switch either AC or DC loads, up to the specified current rating of 0.5A at 120VAC or 0.25A at 240VAC.

How is this module programmed or controlled?

It is a standalone module without a CPU. Its logic is typically controlled by a separate Modicon PLC (like a TSX Micro) via a proprietary bus. It does not run a standalone program.

What is the difference between the main voltage and signal voltage?

The 120/240V AC powers the module's internal circuitry. The 24V DC is used for the low-voltage logic: to power the input sensors and to energize the coils of the internal relays.

Is this suitable for controlling a three-phase motor?

Not directly. The relay outputs are rated for small loads. To control a three-phase motor, you would use one of the module's relays to control a larger motor contactor, which then switches the motor power.

What type of inputs does it accept?

It accepts standard 24V DC digital (discrete) inputs. This includes devices like proximity sensors, selector switches, and other contacts that provide a 24V DC signal when active.

Why choose a module without a communication interface?

It offers a simple, cost-effective solution for local I/O that doesn't require remote networking. It reduces complexity and is ideal for compact control panels where all devices are nearby.
