Information About IS200STCIS6A

The IS200STCIS6A is a Simplex Contact Input Terminal card manufactured by General Electric shell company GE Energy as a drive assembly component for the Mark VIe control system. While manufactured specifically for the Mark VIe, this product is additionally compatible with later Speedtronic control systems including the Mark VIeS series of drive assembly products. It is one of eight versions of the STCI board, and has been revised by a singular functional revision rated at an "A" grade.

Hardware Tips and Specifications

The IS200STCIS6A is a Simplex Contact Input (STCI) terminal board. This small board is designed for flat or DIN-rail mounting.The IS200STCIS6A board accepts twenty-four contact inputs, and nominal 125 Vdc excitation, floating, ranging from 100 to 145 V dc. The IS200STCIS6A PCB's first 21 circuits draw 2.55 mA, and the last three draw 10 mA. It uses plug-in, safety certified terminal strips, with 52 screw connections laid out in two lines of 26 on each terminal strip. On the opposite side of the board from the position of the terminal strips, there is a 37-pin cable connector with latching fasteners on either side of the pin connectors. This plug-in pack is labeled JA1. The IS200STCIS6A board has a 3-position plug (J1) for connection to contact excitation input, as well as several factory-made drilled holes for mounting.

This "STCI"-abbreviated product features a slew of function and on-board signal conditioning features, very much similar to its sister product TBCI. This signal conditioning is scaled for 24, 48, and 128 V dc excitation patterns, with input excitation ranges of 16 to 32 V dc, 32 to 64 V dc, and 100 to 145 V dc respectively. Generally, this module's supported threshold voltage is powered at about half of the present excitation voltage. A series of filters present on the baseplate of the IS200STCIS6A ensure that this module's contact input currents are reduced to 2.5 mA on the first 21 circuits lined up down the side of the PCB. The remaining circuits are limited to an input voltage of 10 mA.

Beyond the various specifications that make up this IS200STCIS6A board's general operations, a number of other components are unique to this STCI model. This Simplex Contact Input Terminal board is a surface-mounted product that measures exactly 6.25 inches high by 4.0 inches wide. It is desginated as nominal under -22 to 149 ºF operational temperature conditions, and is outfitted with a 4 ms hardware filter.

The IS200STCIS6A includes diagnostics like alarm faults on excitation voltage. The board’s connector has a read-only chip that will create a hardware incompatibility fault if it does not match its I/O processor.

Installation Tips and Specifications

While the IS200STCIS6A module certainly sets itself apart from the pack through its detailed list of hardware specifications, it is important to remember a number of specifications to introduce safe and careful replacement of your STCI terminal board; as outlined in GE Energy's Mark* VIe Control Vol. II System Hardware Guide GEH-6721L attached above. The STCI terminal board is designed to mount upon a sheet metal carrier; a carrier which has been specifically introduced to facilitate IS200STCIS6A's concurrent mounting on a greater DIN rail mount. This module, along with its sheet metal carrier, can optionally be mounted in a bolted cabinet for extra sufficient assembly protection. While the shields present alongside the STCI terminal board assembly should be exterior-mounted on a separate bracket; IS200STCIS6A's contact inputs are wired directly to correspondent terminal blocks. Two possible corresponding types of terminal blocks exist, compatible with different styles of IS200 STCI modules. STCIH1-style STCI modules correspond with singular permanently-mounted, 52-terminal terminal blocks, where STCIH2, STCIH4, and STCIH6 models all make use of a right-angle header designed for compatibility across a swathe of industry-recognized pluggable terminal blocks. This header, much like the permanently-mounted terminal block option, possesses a total of 52 terminals. It is of paramount importance to ensure that no power is supplied or present to the IS200STCIS6A terminal board prior to installation, as this printed circuit board carries an electrocution risk when improperly installed.
