FX0S-20MT-DSS Mitsubishi Melsec PLC
24vDC power supply, 12 digital input,8 Transistor output
FX0S-20MT-DSS Mitsubishi Melsec PLC General Overview
The FXOS range of products offer users certain model variations which can .switch higher current output
signals and receive AC input signals. As with all Mitsubishi 'brick' type controllers, the power supply,
CPU and I/O components are presented in a single product. The FXOS is the smallest programmable
controller of its kind manufactured by Mitsubishi. The FXos is totally (100%) compatible in a
programming sense with in FXo counterpart.
FX0S-20MT-DSS Features Include
Wide Tolerance Power Supply;
As with all FX Family programmable controllers, a Wide tolerance power supply means concern free use
any where in the world. AC Supply    100-240V  +10%/-15%
User Friendly Features:
The FXos has a useful RUN/STOP switch, allowing quick and easy operation yet it remains discreetly bidden
next to the programming port In addition there is a single analog potentiometer which can be used to
indirectly change data values, timer durations etc.
Flexible Mounting Arrangements:
AS Witb all FX Family programmable controllers users are offered the choice between 35mm
DIN rail or the use of direct mounting facilities.

FX0S-20MT-DSS Mitsubishi Melsec PLC Large Capacity Service Supply:
'Ihe lOios-'itScMR-ES units are equipped with a 200mA, 24VDCservice Supply. Uses ranf-e from sensor supplies to providing power for additional monitoring peripherals.
FX0S-20MT-DSS Battery-less Backup:
Because of the use ofEEPROM memory in the FX0s, any data which requires storage when the unit is powered down, does not rely on the quality or
availability of a bt4l-tery to provide backup. This makes fflv user friendly AND a minimal mainte­nance product.
FX0S-20MT-DSS High Powered Relay Outputs:
All models of the FXos have high powered relay outputs, these devices protide the ability to switch Currents up lo 2JAmps with an activation
lime of approximately 10 msec.
FX0S-20MT-DSS Smallest Unit Footprint:
The FXos products are the Smallest footprint programmable controllers available from Mitsubishi Flectric Yet the I'Xos ako bus high
powered inputs and output facilities which make it ideal for 'Heavy Duty' applications.
FX0S-20MT-DSS Mitsubishi Melsec PLC Choice of Input Devices:
Users can choose between standard DC tran­sistor inputs providing biub speed counting and interrupt services (up to 7kHz)
OR AC inputs uihicb can accept signals between 85-1.Wat SCrWlti, giving wide unci flexi­ble use In beany engineering applications.
   FX0S PLC handles a broad range of applications
in the low I/O count part of the automation
spectrum. The FX0S can be used simply to gain major savings
in panel space and labor costs when wiring panels, as opposed to
hard-wired relay panels. It also offers you the flexibility of
changing your control specification just by reprogramming, not
rewiring. The FX0S is also an ideal controller for users who are
familiar with the advantages of a PLC, but whose application
requires less than 30 I/O. Some of the benefits
the FX0S can offer you:
• Minimal learning curve before your application’s up and running
when you use  Windows based GPP-WIN programming software.
The powerful Step Ladder
(STL) programming method (originated by Mitsubishi)
makes ladder logic programming even easier by isolating your
program into discrete operations in a sequence.
• The heart of a self-contained sequence
control system with or without our optional user
interfaces for a window on your machine’s
operation (see p. 10 for our HMI line up).
• No matter whether you’re working with AC (100-240 V), DC (12 or 24 V), need transistors or relay switching (up to 2.5 A), or need to keep AC input capability,
the FX0S PLC line-up offers the right PLC type from its wide variety of power and I/O types.
• A fully integrated control package which frees you from the configuration of CPUs, power supplies and I/O systems. The FX0S PLC also includes a 200 mA power supply,
allowing you to remove the hidden cost of a separate sensor power supply in most cases.
• Duplicate an existing relay control scheme in the unit’s 1.6K (800 steps) memory, and still have enough room to add new system features only possible with the FX0S PLC.
• Replace the functions of discrete control relays costing several times that of the PLC by using the FX0S’s comprehensive array of timers, counters and data memory.
• Implement closed loop control by tracking encoders or other pulse generating devices at up to 7kHz, while  imultaneously generating a 2kHz pulse output and hardware interrupts.
Few PLCs in this class can offer you this level of performance.
• Once the FX0S PLC is installed, there is no need for maintenance, and no risk for program loss,due to its battery-free, non-volatile memory.
• If your needs are more sophisticated, the FX0S PLC offers a very capable instruction set which boasts 32 bit math for process calculations, and a
full complement of data handling instructions such as shift registers
