IS420ESWBH1A is a 16-port Ethernet IONet Switch 10/100Base-TX manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. GE's Industrial Ethernet 10/100 switches (ESWA and ESWB) provide the performance and features needed in real-time industrial control systems. Use 8-port ESWA or 16-port ESWB Ethernet switches in all control system I/O networks to maintain the reliability needed for I/O module reception of controller outputs.
DISTRIBUTED I/O MODULES:
The I/O modules contain three basic parts: terminal board, terminal block, and I/O pack. The terminal board mounts to the cabinet and comes in two basic types: S and T. The I/O pack mounts to the terminal board J-port connector. Both terminal board types provide the following features:
Terminal blocks for I/O wiring
Mounting hardware
Input isolation and protection
I/O pack connectors
Unique electronic ID
I/O PACKS:
I/O packs have a common processor board and a data acquisition board that is unique to the type of connected device. I/O packs on each terminal board digitize the I/O variables, perform algorithms and communicate with the controller. The I/O pack provides fault detection through a combination of special circuitry in the data acquisition board and software running in the Central Processing Unit (CPU)board. The fault status is transmitted to and used by the controllers. The I/O pack transmits inputs and receives outputs on both network interfaces if connected. Each I/O pack also sends an identification message (ID packet) to the main controller when requested. The packet contains the hardware catalog number of the I/O board, the hardware revision, the board barcode serial number, the firmware catalog number, and the firmware version. The I/O packs have a temperature sensor that is accurate to within ±2°C (±3.6 °F). Every I/O pack temperature is available in the database and can be used to generate an alarm.
TERMINAL BOARDS:
Signal flow begins with a sensor connected to a terminal block on a board. Wide and narrow terminal boards are arranged in vertical columns of high and low-level wiring. An example of a wide board is a board that contains magnetic relays with fused circuits for solenoid drivers. A shield strip is provided to the left of each terminal block. It can be connected to a metalbase for immediate grounding or floated to allow individual ground wires from each board to be wired to a centralized, cabinet ground strip.
