Product Overview

The Omron CP1L-EM30DT-D is the 30-I/O Ethernet-equipped compact PLC in the CP1L-EM line, 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 CP1L-EM30DT-D carries 18 DC inputs and 12 NPN-sinking transistor outputs on the base unit, a built-in 10/100 base-T Ethernet port for FINS/TCP, FINS/UDP, and socket service, 10K steps of program memory, and a 24 VDC supply on the same removable terminal block. The DT suffix marks NPN (sinking) outputs; the EM suffix marks Ethernet. Built-in motion includes 4-axis 100 kHz high-speed counter inputs and 2-axis 100 kHz pulse outputs.

Up to 3 CP1W expansion units add up to 160 I/O. One option-board slot accepts the CP1W-CIF11 (RS-422A/485) or CP1W-CIF12-V1 (isolated RS-485) for Modbus-RTU or Host Link serial. For AC supply, use CP1L-EM30DR-A or CP1L-EM30DT-A. For PNP outputs, use CP1L-EM30DT1-D. For Ethernet only, the CP1L-EL20DT-D saves footprint at 20 I/O.

Key Features

  • CP1L-EM-series 30-I/O compact PLC with built-in 10/100 base-T Ethernet port
  • 18 DC inputs + 12 NPN-sinking transistor outputs on the base unit, 24 VDC supply
  • 4-axis 100 kHz high-speed counter + 2-axis 100 kHz pulse output, 10K-step program
  • One option-board slot for CP1W-CIF11 / CP1W-CIF12-V1 serial, up to 3 CP1W expansions
  • SKU: CP1L-EM30DT-D
  • Series: CP1L-EM30DT-D
  • Voltage: 24 VDC
  • I/O: 18 I/O

Best-Fit Applications

  • Packaging line control with two inverter pulse-following axes and one Ethernet link to an NB7W-TW01B-V1 HMI
  • Small conveyor cell with 4-axis 100 kHz HSC for encoder feedback plus Ethernet SCADA polling
  • Test fixture with Modbus-RTU on a CP1W-CIF11 option board plus Ethernet for remote upload

Buying Checklist

  • Pick the CP1L-EM30DT-D for 30 I/O with built-in Ethernet, 4-axis 100 kHz HSC, and 2-axis pulse output on 24 VDC.
  • Pick the CP1L-EM30DT1-D instead when the load is PNP (sourcing) rather than NPN (sinking).
  • Pick the CP1L-M30DT-D when the cabinet has no Ethernet and program upload is USB only.

FAQ for CP1L-EM30DT-D

What is the Omron CP1L-EM30DT-D used for?
It is the 30-I/O Ethernet-equipped compact PLC in the CP1L line for small machines needing 4-axis HSC, 2-axis pulse output, and remote HMI / SCADA access.
CP1L-EM30DT-D vs CP1L-M30DT-D — what is the difference?
Both are 30-I/O CP1L heads with 4-axis 100 kHz HSC. The EM30DT-D has built-in 10/100 base-T Ethernet; the M30DT-D does not.
Does the CP1L-EM30DT-D support CP1W expansions?
Yes. Up to 3 CP1W expansion units chain off the right side, taking total I/O to 160. A CP1W-CIF11 or CP1W-CIF12-V1 option board adds one serial port.
What supply voltage does the CP1L-EM30DT-D need?
24 VDC on the removable terminal block (the -D suffix). The -A suffix is the 100-240 VAC variant.
How do I configure the CP1L-EM30DT-D in CX-Programmer?
Connect USB or Ethernet, create a CP1L-EM device in CX-Programmer under CX-One, and the I/O table auto-loads from the head.
