FUNCTIONAL DESCRIPTION:

IS200SAIIH1A is a Simplex Analog Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Simplex Analog Input (SAII) terminal board connects to the PAIC and is a small analog input terminal board that supports 10 analog inputs and two analog outputs. The I/O pack connects to the D-type connection and uses Ethernet to interact with the controller. Two-wire, three-wire, four-wire, or externally powered transmitters can connect to the 10 analog inputs. Point isolation is a property of each analog input when it is set up for externally powered devices. The circuit has an isolator with a 1500 V rms rating for each analog input. The two analog outputs are each 0-20 mA, however, when used with a PAICH2, one can be jumper-configured to be 0-200 mA current. Terminal blocks of the Euro-block type with high density are employed.

INSTALLATION:

The SAII is mounted along with a plastic insulator on a sheet metal carrier, which is subsequently mounted to a DIN rail. The SAII plus insulator can instead be mounted on a sheet metal assembly and fastened directly to a cabinet using bolts. Euro-block terminal blocks come in the following two varieties:

• SAIIH1 has a 48-terminal terminal block that is permanently mounted.
• SAIIH2 has a right angle header that can accommodate a variety of pluggable terminal blocks that are readily accessible and have a total of 48 terminals.

OPERATION:

All of the transmitters have access to 24 V DC power on the terminal board (transducers). With the use of jumpers, current or voltage inputs are selectable. One of the two analog output circuits can be adjusted through a jumper for 4-20 mA or 0-200 mA. Since there is only one PAIC connection, TMR applications, such TBAI, cannot be used with the terminal board.

CONFIGURATION:

Jumpers configure the terminal board. For the location of these jumpers, refer to the installation diagram. The jumper choices are as follows:

• Current input or voltage input can be chosen using the jumpers JP1A through JP8A.
• The 20 mA or 1 mA input current can be selected using the jumpers JP9A and JP10A.
• The return is either linked to common or left open depending on the setting of jumpers JP1B through JP10B. Any JP1B to JP10B will not have a point-isolated channel when it is in use and the return is connected to common.
• When used with a PAICH2 I/O pack, jumper JP11 changes output 1's current to either 20 mA or 200 mA.
