About the IS200TRTDH1CBB

The IS200TRTDH1CBB is a PCB component made by GE for the Mark VI system. The Mark VI, which is one of several systems released under the Speedtronic line, is designed for the management of gas and steam turbines.  

The  IS200TRTDH1CBB is an RTD Input terminal card that accepts sixteen three-wire RTD inputs.  All inputs to this board are designed with noise suppression in order to protect against surge and high-frequency noise.  This PCB communicates with an I/O processor, which converts inputs to digital temperature values and then sends these to the controller.  

The  IS200TRTDH1CBB is a simplex board.  It connects to a single VRTD board using two cables that connect to two (female) DC-37 connectors located on the IS200TRTDH1CBB board. These connectors are labeled JA1 and JB1. The board has two 24-screw connection terminal blocks (TB1 and TB2) that can be disconnected from the board to allow for maintenance when needed.  It has two oval cutouts for screw mounts and also has a shield bar connected to the left long side of the board.

The  IS200TRTDH1CBB supplies a non-continuous 10 mA dc excitation current to each RTD.  These RTDs connect to the turbine control cabinet using a two-way cable with a resistance of 15 Ω and can be located up to 300 meters (984 feet) away.  The RTDs can be either ungrounded or grounded.

The  IS200TRTDH1CBB  has no hardware settings or jumpers but does include various diagnostic checks, including hardware limit checking and software limit checking.  More information may be found by accessing GE publications like manuals and user guides.
