Introduction

Easy Maintenance

The NA-4020/4021 series network adapter can be expanded by adding up to 32 I/O modules. It can provide spring type, removable terminal blocks (RTBs) that allow you to preserve field wiring before replacing an I/O expansion module. Each I/O expansion module can be replaced quickly and easily.
