Omron NT20M-DN121-V2 is an NT20M-series programmable operator terminal designed for panel-mounted machine and process indication in compact control cabinets. This model is a non-touch HMI with a monochrome STN LCD offering a 256 × 128 dot resolution across a 4.4 × 2.2 inch display area, with cold-cathode backlighting for clear readability. It is supplied as a terminal with no onboard screen memory, making it suited to installations where the appropriate memory device is fitted to match the application’s screen and data requirements.
The NT20M-DN121-V2 supports flexible host connectivity via plug-in interface modules, enabling integration with common Omron control architectures and serial communications such as RS-232C or RS-422 when the relevant interface unit is installed. Typical uses include status display, alarm annunciation, basic operator interaction via external or optional key units, and consolidating multiple discrete indicators into a single, configurable interface. With a shallow panel depth and compact footprint (approximately 110 H × 220 W × 82 D mm for the NT20M-DN housing), it is a practical choice for space-conscious industrial panels where a keypad-style, non-touch interface is preferred.

| Description | Omron NT20M-DN121-V2 is a compact NT20M-series programmable terminal with a crisp monochrome STN LCD and a non-touch operator interface, designed to present machine and process information clearly in panel-mounted applications where a dedicated display terminal is preferred over a touch screen. |
What type of operator interface is this unit used for?
It is a compact NT20M-series programmable terminal used as an operator interface for viewing machine status and interacting with screens configured for an automation system.
Is the front panel touch-enabled?
No. This model is the non-touch (DN) version, intended for operation via keys rather than a touchscreen.
Does the unit include built-in screen memory?
No. This version is supplied with no memory fitted, so a compatible screen memory device must be installed to store screen data.
What display size and resolution does it use?
It uses an STN LCD with a 4.4 x 2.2 inch display area and a 256 x 128 resolution.
What type of backlight does it have?
It uses a cold cathode tube backlight.
What are the approximate physical dimensions of the unit?
Approximate dimensions for the NT20M-DN style housing are 110H x 220W x 82D mm.
How many screens can typically be handled on this platform?
The NT20M platform supports up to 250 screens, including overlapping and chained (continuous) screen functions.
What communication options can be used with this terminal?
Communication is provided via a plug-in host interface unit. Common options include RS-232C and RS-422 interface units, as well as Host Link/SYSMAC-related interface options depending on the installed module and ROM combination.
What cable distance limits apply for RS-232C and RS-422 connections?
Typical limits are up to 15 m for RS-232C and up to 500 m for RS-422 (including branch wiring), provided the connection is implemented using the correct interface unit and wiring practices.
Can a function key unit be added for extra operator input?
Yes. A 12-key function key unit is available for the NT20M series, allowing additional key-based operator input when required.
Which screen memory types are commonly used with this terminal family?
Depending on the application, SRAM, EPROM, or EEPROM memory devices may be used for screen data storage on the NT20M/NT2000M platform. The correct choice depends on how the screens are intended to be stored and managed.
Are there any key configuration considerations when selecting interface modules and ROMs?
Yes. Certain interface modules require specific system ROM versions to operate correctly. When configuring an NT20M-DN121-V2 installation, ensure the selected host interface unit and system ROM are a compatible pairing.
