Product Overview
The Omron CP1L-L20DR-A is an L-type basic CPU unit from the CP1L compact PLC family It is manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The unit ships with 12 digital inputs (24 VDC) and 8 relay outputs (2 A) on a 20-point terminal block. Program capacity is 5K steps and data memory is 10K words.
The body is 86 x 90 x 85 mm, IP20, DIN-rail mounted. Key specs: Supply Voltage 100 to 240 VAC, 50/60 Hz; Digital Inputs 12 x 24 VDC; 4 double as 100 kHz high-speed counters; Digital Outputs 8 x relay, 250 VAC 2 A resistive; Program Capacity 5K steps; Data Memory 10K words; LD Execution Time 0.55 us per basic instruction; Built-in Ports USB 2.0 B-type (programming); 1 option-board slot; Expansion / Aux Output 1 CP1W expansion unit (up to 60 I/O); 200 mA aux 24 VDC.
Key Features
- CP1L-L basic CPU with 12 digital inputs and 8 relay outputs (2 A)
- 5K steps program, 10K words data, 0.55 us LD execution, 100 kHz high-speed counter on 4 inputs
- Built-in USB plus option-board slot for RS-232C, RS-485 or Ethernet
- 100 to 240 VAC supply, real-time clock, 200 mA aux 24 VDC, 1 CP1W expansion unit
- SKU: CP1L-L20DR-A
- Series: Omron CP1L-series L-type compact PLC
- Voltage: 100 TO 240 VAC
Best-Fit Applications
- Compact machine controller where the 4 high-speed counter inputs read an E6B2-CWZ6C 2000P-R encoder and the 8 relays drive solenoid valves
- Standalone cell with an NB5Q-TW01B-V1 HMI over RS-232C where the option slot takes a CP1W-CIF01 board and the cabinet runs on AC supply
- Spare CPU drop-in for an existing CP1L cell where the previous CP1L-L20DR-A failed and the field wiring is AC supply with relay outputs
Buying Checklist
- Pick the CP1L-L20DR-A for a 20 I/O CP1L CPU with relay outputs and an AC supply.
- Pick the CP1L-L20DT-D instead when the panel needs 24 VDC supply and NPN transistor outputs instead of relays.
- Pick the CP2E-N20DR-A instead when the cabinet needs a current-production CPU with the same 20 I/O footprint.

FAQ for CP1L-L20DR-A
When does production of the CP1L-L20DR-A end?
Omron has announced that production of the CP1L-L20DR-A is planned to end on 2027-03-31. Spare stock is sold through that date and the unit is supported after. For a current-production alternative, use the CP2E-N20DR-A.
What option boards fit the CP1L-L20DR-A?
The CP1L option slot takes one board at a time: CP1W-CIF01 (RS-232C), CP1W-CIF11 (RS-422A/485 non-isolated), CP1W-CIF12-V1 (RS-422A/485 isolated) or CP1W-CIF41 (Ethernet). The board plugs into the top of the CPU; no wiring changes are needed.
Can the CP1L-L20DR-A read a 100 kHz encoder?
Yes. Inputs 0, 1, 2 and 3 double as 100 kHz high-speed counters, so the L20 can read a 2000 P/R encoder such as the E6B2-CWZ6C 2000P-R at up to 3000 r/min without losing counts.
What replaces a failed CP1L-L20DR-A?
A second CP1L-L20DR-A with the same firmware is a direct drop-in. For a current-production alternative, the CP2E-N20DR-A matches the 20 I/O footprint and AC supply.
