SE4001S2T2B  DeltaV™ S-series Traditional I/O

Introduction
S-series traditional I/O interfaces provide improved ease of installation with the same proven features of M-series I/O interfaces. This modular I/O subsystem offers flexibility during installation and is designed for extreme environmental conditions of field installations. S-series traditional I/O is equipped with a snap-in retention system for quick installation.
The I/O interfaces can be installed in any of the possible 64 slots.
All wiring is through the carriers and terminal blocks so that modules can easily be removed without disconnecting any wires. Modularity, fast installation, online expansion, and environmentally robust hardware make DeltaV™ S-series traditional I/O a smart choice for your process control system.
Benefits
Modular and flexible construction: The S-series traditional I/O subsystem is designed with your investment in mind.
Each controller supports up to eight I/O carriers that form a robust, passive bus for up to 64 I/O interfaces. Each interface has a matching I/O terminal block and can be installed in any I/O slot on the bus. Carriers and interfaces can be added online, without interruption to the existing I/O communication.
This modular design enables you to purchase the exact amount of I/O cards, eight-wide carriers, power/controllers, and two-wide carriers you need and add more DeltaV I/O as your system grows.

Reduced installation time and expense: The DeltaV system’s S-series I/O interfaces are designed for quick assembly and error proof maintenance. All carriers snap onto T-DIN rails and interfaces snap into the I/O slots without the use of any tools.
Each I/O interface has a separate wiring terminal block, which connects field wiring to the interface. The I/O card can easily be removed without touching the I/O wiring on the terminal block. Some I/O cards can also use the fused terminal block, which is equipped with in-line fuses that can be pulled to isolate power to the field circuit.
Traditional I/O interfaces have I/O function keys that allow the terminal block to be set to receive a specific I/O card.
These keys ensure that the correct I/O card is always plugged into the corresponding terminal block. The keys provide a safety measure by preventing the wrong I/O card being installed. It’s incredibly easy to use and gives you time to do more.
