事件序列 (SOE) 记录器可报告低至 6 ms 的接触颤动和脉冲宽度，以及时间分辨率为 1 ms 的所有接触打开和关闭。继电器输出：TRLYH1B 中存储有 12 个插入式磁继电器。跳线可用于设置前 6 个继电器电路，用于驱动外部螺线管或干式 C 型触点输出。对于现场电磁阀电源，可以提供标准 125 V 直流或 115 V 交流电源以及可选的 24 V 直流电源，并配有单独的跳线可选熔断器和板载抑制。随后的五个继电器 (7-11) 具有未通电的独立 C 型触点。输出 12 使用隔离的 C 型触点，用于点火变压器等特殊应用。
IS200VCRCH1B
IS200VCRCH1B is a part of the Mark VI series used in gas turbine control systems for contact input/relay output boards manufactured by General Electric. The contact input/relay output board accepts 48 discrete inputs and manages 24 relay outputs from a total of four terminal boards through its accompanying sub boards. The dual width VCCC module is installed in the VME I/O rack. Two sets of J3/J4 connections are provided in this rack for connecting to TBCI and TRLY terminal boards. Contact input: The contact input terminal board (TBCI) is used for the first 24 dry contact inputs; Input 25-48 requires a second terminal block. The contacts provide DC power. The terminal board is connected to the VME rack equipped with a VCCC processor board through a cable with a molded plug. For monitoring inputs of key turbine variables, high-speed scanning and recording can be performed at 1 millisecond per second.

The Event Sequence (SOE) recorder can report contact tremors and pulse widths as low as 6 ms, as well as all contact opening and closing with a time resolution of 1 ms. Relay output: TRLYH1B stores 12 plug-in magnetic relays. Jumpers can be used to set the first six relay circuits to drive external solenoid or dry C-type contact outputs. For on-site solenoid valve power supply, standard 125 V DC or 115 V AC power supply and optional 24 V DC power supply can be provided, with separate jumper optional fuses and onboard suppression. The following five relays (7-11) have independent C-type contacts that are not energized. Output 12 uses isolated C-type contacts for special applications such as ignition transformers.
