Functional Description

IS200STCIS2A is a Simplex Contact Input Terminal Board developed by GE. It is a part of Mark VIeS control system. This compact and space-efficient terminal board is designed for DIN-rail mounting and integrates seamlessly with Mark VIeS systems, making it an ideal choice for control and monitoring applications. The board supports up to 24 contact inputs and operates with nominal excitation voltages of 24 V, 48 V, and 125 V DC sourced externally. Equipped with advanced noise suppression, it protects against surges and high-frequency interference, ensuring reliable operation in demanding industrial environments.

Features

• The terminal board supports up to 24 contact input channels, accommodating field signals from switches, relays, and other dry contact devices. It operates with externally sourced DC excitation voltages of 24 V, 48 V, or 125 V, offering flexibility to meet varied system requirements. Each contact input is detected based on a 50% voltage threshold of the supplied excitation voltage, ensuring accurate and consistent signal recognition. This makes the board especially effective for precise state detection in safety systems and control loops.
• Input current is carefully managed to suit different application needs. The first 21 channels are limited to 2.5 mA, offering safe and efficient sensing for standard control inputs. Channels 22 to 24 support higher current up to 10 mA, providing adaptability for more demanding field devices. To protect the board and the system, a built-in 24 V DC power supply is safeguarded by resettable polymer PTC fuses, which limit current to 0.5 A during fault conditions and automatically reset once normal conditions are restored. This eliminates the need for manual fuse replacement, enhancing maintainability and uptime.
• Noise suppression and surge protection are key strengths of the component. Each input channel is equipped with dedicated high-frequency filters that effectively block electromagnetic and radio frequency interference (EMI/RFI). In addition, built-in surge protection ensures stability in environments with frequent electrical disturbances, such as motor control centers or high-voltage switchgear systems. These features collectively safeguard signal integrity and prevent misreads or false triggers.
• The board’s signal processing path includes optical isolation, which electrically separates the input signals from the rest of the system to protect against ground loops and transient voltages. Once isolated, the discrete signals are digitally converted and transmitted to the system controller via the onboard I/O processor. This ensures accurate, interference-free communication and contributes to the overall safety and reliability of the control architecture.
• For connectivity, the board features a 37-pin female RS-232 port located at the top center edge, allowing for straightforward communication and integration with diagnostics or controller systems. Its DIN-rail mountable design and streamlined layout make installation quick and efficient, while its rugged construction ensures consistent performance over time.
