I/O modules

Core Technical Specifications

This relay terminal board manages discrete I/O signals for GE Mark V systems. DS200RTBAG3A DS200RTBAG3AGC measures 30.5 cm in width and 25.4 cm in depth. The unit weighs roughly 1.1 kg without any cables attached. You will find 24 screw-type terminal blocks on this board. Each terminal accepts 12–22 AWG wires for field connections. The assembly includes 16 relay components onboard. Four of these relays handle high-current switching duties. Transitioning to power requirements, the board needs 28 V DC input. It also draws 250 mA under normal operating conditions.

Component Layout and Energy Storage

The PCB uses a four-layer design for better signal isolation. Eight LEDs indicate relay status at a glance. DS200RTBAG3A DS200RTBAG3AGC contains two 16-pin header connectors for backplane communication. For energy storage, the board features six electrolytic capacitors. Each capacitor stores 220 µF at 50 V. This setup filters power supply noise effectively. Accordingly, the board tolerates input voltage ripple up to 5%. Three jumper switches let you configure each relay’s default state. The operating temperature range spans 0°C to 55°C. Meanwhile, humidity tolerance reaches 95% without condensation.

Interface and Mechanical Details

Four mounting brackets secure the board to standard racks. DS200RTBAG3A DS200RTBAG3AGC offers 1500 V isolation between field and logic sides. Each relay supports switching up to 2 A at 30 V DC. Transitioning to physical protection, a conformal coating covers all traces. This coating resists dust and moisture ingress effectively. You can replace the board in under 15 minutes during maintenance.
