- Stores the control program and operating data within a 48K-word PLC-5 memory space
- Links programming and plant-network communications through its built-in Ethernet TCP/IP connection
- Assigns two separate channels to Data Highway Plus or remote-I/O duties as required by the rack design
1785-L40E serves installations that require more memory and I/O architecture than the L20E class while retaining the PLC-5 programming model.
Its communication layout separates Ethernet from the two channels that may be assigned to Data Highway Plus or remote I/O.
The larger rack allowance makes accurate restoration of chassis addresses and scanner relationships critical during a controller change.
Availability, condition, price, and shipping time for 1785-L40E are confirmed during quotation.
