FUNCTIONAL DESCRIPTION:
IS200STURH3A is a Simplex Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The Simplex Primary Turbine Protection Input (STUR) terminal board is a simplex S-type terminal board version of the turbine terminal board (TTUR). It provides a connection for the turbine-specific primary trip (PTUR), speed and synchronizing inputs, and trip relay outputs or a cable to drive a primary trip board. STUR is used for the following:
This terminal board has the same physical size, customer terminal locations, and I/O pack mounting as other S-type terminal boards. There will be no components higher than an attached PTUR I/O pack permitting double stacking of terminal boards. There are four groups:
OPERATION:
BOARD GROUPS: STUR is available in four distinct configurations. STUR is not available with fixed box terminals. It uses pluggable type terminals. Two groups offer on-board trip relays and two groups offer DC-37 pin connectors for using an external trip board. Components supporting generator applications will be omitted from two groups used for mechanical applications and added for groups used for generator applications.
SPEED INPUT: STUR provides four-speed input circuits that accept passive speed sensors or active speed sensors. When passive sensors are used the signal is applied between terminals PR#_H and PR#_L where # is 1 through 4. The sensitivity of the passive sensor input is such that the PTUR I/O pack can sense speeds as low as 2RPM. When active speed sensors are used the signal is applied between terminals TTL# and PR#_L.
TRIP RELAYS: STUR versions H1 and H2 provide two trip solenoid outputs, K1 and K2, with each composed of a safety relay that uses forcibly guided contacts. Relay position feedback is provided to PTUR using one of the contact pairs in the relay. Extra customer terminals are provided to allow connecting two or three STUR boards in a redundant tripping configuration.
PRIMARY SYNCHRONIZING: STURH2 and STURH4 used with PTUR provide support for synchronized closure of a 52G primary breaker. Two PT inputs are provided for Bus and Generator voltage on terminals 21 through 24. Breaker positive power at 24, 48, or 125 V dc is applied to terminal 27 (PGEN) and the return is applied to terminal 32 (NGEN). The presence of this voltage is indicated by the BKRVLT signal. Positive power passes through a permissive relay K25P to terminal 28 (AUTO) with power indicated by the BKRPRM signal. Power then passes through the synchronizing pilot relay K25 to terminal 29 (MAN) as indicated by the BKRGES signal.

How is a simplex terminal board different from other terminal boards?
A simplex terminal board is designed for basic wiring applications where only single connections are required. In contrast, complex terminal boards may offer features like multiple levels, fused connections, or specific circuitry for more sophisticated setups.
What are the common applications of simplex terminal boards?
Simplex terminal boards are commonly used in various electrical systems such as control panels, distribution boards, industrial machinery, and home wiring installations. They provide a reliable means of connecting wires straightforwardly.
How do I install a simplex terminal board?
Installation of a simplex terminal board typically involves mounting it securely to a surface using screws or other fasteners. Wires are then inserted into the screw terminals and tightened securely to establish electrical connections.
