FUNCTIONAL DESCRIPTION:

IS200SAIIH2ACD is a Simplex Isolated Analog Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Speedtronic Turbine Control Systems. The Simplex Analog Input (SAII) terminal board is a compact analog input terminal board that accepts 10 analog inputs offers two analog outputs, and connects to the PAIC. The I/O pack plugs into the D-type connector and communicates with the controller over Ethernet. The 10 analog inputs accommodate 2-wire, 3-wire, 4-wire, or externally powered transmitters. Each analog input features point isolation when configured for externally powered devices. Each analog input has an isolator in the circuit with a rating of 1500 V rms. The two analog outputs are 0-20 mA but one can be jumper configured to 0-200 mA current when used with a PAICH2. High-density Euro-block type terminal blocks are used. An on-board ID chip identifies the SAII to the PAIC for system diagnostic purposes.

INSTALLATION:

The SAII plus a plastic insulator mounts on a sheet metal carrier that then mounts on a DIN rail. Optionally, the SAII plus insulator mounts on a sheet metal assembly and then bolts directly to a cabinet. There are two types of Euro-block terminal blocks available as follows:

• SAIIH1 has a permanently mounted terminal block with 48 terminals
• SAIIH2 has a right-angle header accepting a range of commercially available pluggable terminal blocks, with a total of 48 terminals

OPERATION:

24 V dc power is available on the terminal board for all the transmitters (transducers). There is a choice of current or voltage inputs using jumpers. One of the two analog output circuits is 4-20 mA, and the other can be jumper configured for 4-20 mA or 0-200 mA. There is only one PAIC connection, so the terminal board cannot be used for TMR applications as with TBAI.

FREQUENTLY ASKED QUESTIONS:

What is the purpose of the Simplex Isolated Analog Input Terminal Board?

The Simplex Isolated Analog Input Terminal Board is designed to receive analog input signals while providing electrical isolation between the input signals and the control system, enhancing safety and signal integrity.

What types of signals can the terminal board handle?

The board can handle various analog signals, including voltage (e.g., 0-10V) and current (e.g., 4-20mA) inputs.

How is the isolation provided?

Isolation is typically achieved through the use of isolation amplifiers or transformers, which prevent ground loops and protect the control system from high voltages.
