In systems where components are separated by large distances or where an extreme amount of I/O is needed, remote I/O points can be located separately from the CPU base and linked through communication. DirectLOGIC 405 Ethernet Remote I/O modules provide a 10/100 Mbps Ethernet link between a CPU and remote I/O bases.

DirectLOGIC DL405 PLC - Remote I/O Ethernet Modules

With the DirectLOGIC DL405 programmable logic controller (PLC), remote I/O capability is made easy with Ethernet remote master (ERM) and Ethernet base controller (EBC) modules. Remote bases can be located up to 1,000 meters away without a switch. DL405 Ethernet modules include those listed below.

Ethernet Remote Master (ERM) Modules - H4-ERM100
Ethernet Base Controller (EBC) Modules - H4-EBC, T1H-EBC and T1H-EBC100

Ethernet Remote Master Modules (H4-ERM100)

H4-ERM100 10/100BaseT Ethernet Remote Master Module

with 100Mbps data transfer rate; TCP/IP, IPX, Modbus TCP/IP, DHCP Ethernet protocols; HTML configuration
The Ethernet Remote Master H4-ERM100 connects DL440 and DL450 CPU systems to Ethernet Base Controller (EBC) slave I/O over a high-speed Ethernet link.

Each ERM100 module can support up to 16 DL205 EBC systems (H4-EBC) or 16 GS1/GS2 Series or DURApulse (GS3 Series) AC drives via GS-EDRV100 units. Of course, combinations are fine, too.

DL405 PLC Ethernet Remote Master (ERM) Modules Overview

Ethernet Base Controllers (H4-EBC, H2-EBC, H2-EBC100, T1H-EBC and T1H-EBC100)

The various Ethernet Base Controller modules (EBCs) provide a low-cost, high-performance Ethernet link between DirectLOGIC DL205, DL405 or Terminator I/O and your PC-based control system or WinPLC/ DL205/ DL405 CPUs using the H*-ERM module for remote I/O. The EBC100 models can also be used to connect DirectLOGIC PLC and Terminator I/O to a MODBUS TCP/IP client (master).

EBCs also offer:

Lower cost on your DirectLOGIC PLC I/O system when compared to competitive I/O alternatives
Virtually unlimited number of I/O points
Deterministic I/O updates on dedicated networks
Use off-the-shelf networking components to connect to your existing network
Fast I/O updates (less than 1 ms per base)
On-board serial port for an operator panel, ASCII devices (serial port not supported when used with the H4-ERM module)
