Omron CP1L-M40DR-D is a compact CP1L-series PLC CPU Unit designed for flexible machine control with a 24 V DC power supply and a built-in 40-point I/O configuration. It provides 24 digital inputs (24 V DC, PNP/NPN compatible) and 16 relay outputs rated up to 2 A, making it well suited to switching a broad range of field devices while maintaining electrical isolation at the outputs.
With a 10K-step program capacity and 32K words of data memory, the CP1L-M40DR-D supports practical, mid-sized control applications requiring reliable logic handling and fast response; basic instruction execution is as low as 0.55 μs. A built-in USB port is provided for direct connection to a PC, and additional communications can be added via optional boards (including serial and Ethernet options). The unit also supports expansion with up to three CP1W expansion units for scaling I/O (up to 160 local I/O points), and includes high-speed counter capability with up to four encoder input channels (up to 100 kHz) for counting and measurement tasks.

| Product Description | A compact Omron CP1L M-type PLC CPU designed for 24 V DC control panels, combining 24 DC inputs and 16 relay outputs in a single unit. With 10K steps of program capacity and fast instruction processing, it suits general-purpose machine automation where flexible relay switching and straightforward expansion are required. |
What type of power supply does this PLC require?
It is a 24 V DC powered CPU unit. The operating voltage range is 20.4 to 26.4 V DC.
How many digital inputs and outputs are built in?
It has 24 built-in digital inputs (24 V DC) and 16 built-in relay outputs (rated 2 A).
Can the digital inputs be wired as PNP or NPN?
Yes. The built-in 24 V DC inputs support PNP/NPN wiring, allowing common sourcing or sinking arrangements depending on how the input commons are wired.
Are the built-in outputs relay or transistor?
The built-in outputs are relay outputs (16 points). If pulse outputs are required, that is typically associated with transistor-output CPU variants rather than this relay-output model.
Does it have an Ethernet port built in?
No. This CPU has no built-in Ethernet port. Ethernet connectivity can be added using an optional Ethernet option board (for example, CP1W-CIF41) in the option board slot(s).
What communications ports are available on the CPU itself?
It includes a built-in USB port for connection to a PC. Additional communications can be added via option boards (for example RS-232C or RS-422/485), depending on the application.
Can I add RS-232 or RS-485 communications?
Yes. Serial communications can be added using option boards such as RS-232C (CP1W-CIF01) or RS-422/485 (CP1W-CIF11), including an isolated RS-422/485 option (CP1W-CIF12-V1).
How much programme and data memory does it have?
Programme capacity is 10K steps, and data memory capacity is 32K words.
What is the basic instruction execution time?
The basic instruction execution time is specified as 0.55 μs (minimum).
Does it support high-speed counting / encoder inputs?
Yes. It supports 4 encoder input channels, with a maximum encoder input frequency of 100 kHz.
Can it provide pulse outputs for positioning?
Not on this relay-output CPU. The maximum pulse output frequency is specified as 0 kHz for this model.
How many expansion units can be connected?
Up to 3 expansion units can be connected, with a maximum of 160 local I/O points (including the built-in I/O).
Can analogue signals be used with this PLC?
Yes, via expansion analogue I/O units. The system supports up to 25 analogue I/O channels (system maximum). Note that some analogue option boards apply only to specific CPU types, so analogue expansion is commonly achieved using CP1W analogue units with this CPU.
Does it include an analogue input for a simple setpoint?
Yes. CP1L-M type CPUs include an external analogue setting input (0 to 10 V) intended for simple setpoint/adjustment use rather than full-feature analogue I/O.
Does it have a real-time clock?
Yes, a real-time clock function is supported.
What are the operating temperature limits?
The operating temperature range is 0 to 55 °C.
What are the approximate dimensions of the unit?
The published unpacked dimensions are approximately 150 mm (W) × 90 mm (H) × 85 mm (D).
Is it suitable for DIN-rail mounting?
Yes. The unit is designed for standard control panel installation and is commonly mounted on DIN rail, with additional mounting options depending on the enclosure layout.
How is programme/data retention handled during power loss?
User programmes and settings are stored in non-volatile memory. For retention of certain data areas (such as Holding Area, DM Area and counter values), a battery can be used; CP1L-M40DR-D supports an optional battery.
