IS200ECTBG2A

Overview

The IS200ECTBG2A is an automation component from GE. It is part of GE's industrial automation product portfolio.

Application & Technical Notes

As an automation component, the IS200ECTBG2A is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.

Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.

Maintenance & Diagnostics

Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the IS200ECTBG2A, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm mechanical and electrical compatibility with your GE product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications

SPECIFICATIONS: Part Number: IS200ECTBG2A Manufacturer: General Electric Series: EX2100 Relay Break Characteristic: 28 V dc Operational Mode: Simplex mode only Customer Power: 125 V dc Function: Exciter Contact Terminal Board Relay Control Voltage: 24 V DC Wetting Voltage: 70 V DC Weight: 0.34 kg Dimensions: 150 x 76 x 90 mm Availability: In Stock Country/Region of Manufacture: United States Manual: GEI-100457A FUNCTIONAL DESCRIPTION: IS200ECTBG2A is an Exciter Contact Terminal Board manufactured by General Electric as part of the EX2100 series used in the Excitation control system. The ECTB board supports excitation contact outputs and contact inputs. The ECTBG2 board is only used in the simplex mode. Each board contains two trip contact outputs driving a customer lockout, and four general-purpose Form-C relay contact outputs, controlled by the EMIO board. Six auxiliary contact inputs are powered (wetted) with 70 V dc by ECTB. Also, the 52G and 86 G contact inputs are powered and monitored by ECTB. In the redundant case, power comes from the M1 and M2 power supplies. There are also four general-purpose Form-C contact outputs controlled by the EMIO board. Six auxiliary contact inputs are powered (wetted) with 70 V dc and monitored by ECTB. Also, the 52G and 86 G contact inputs are powered with 70 V dc and monitored. In the redundant control, power comes from both the M1 and M2 controllers. RELAY CONTROL AND FEEDBACK: Trip Relay Outputs (Simplex/Redundant): ECTBG2, driven by the EMIO in M1, controls two trip relays normally used as customer lockout drivers. The relay drivers are powered by 24 V dc from the M1 controller. Refer to the previous figure ECTBG2 Terminal Board, Simplex. Each customer lockout is driven by one relay using two parallel normally closed contacts. On the board, the relays are designated K1M1 and K2M1. For redundant control operation with ECTBG1, the three inputs drive three relays that control a 2- out of 3 contact voting circuit. GENERAL PURPOSE RELAY OUTPUTS (Simplex/Redundant): ECTBG2 controls four general-purpose relay outputs. The relay drivers are powered by 24 V dc from the M1 controller. Each relay output is a Form-C type with normally open, normally closed, and common terminals. Customer power, nominally 125 V dc, is wired to these terminals. On the board, the relays are designated K1GP, K2GP, K3GP, and K4GP. For redundant operation with ECTBG1, the three inputs are voted in the relay driver, which drives the single coil. CONTACT INPUTS: Contact input uses are similar in the simplex and redundant cases, however, the inputs are fanned to the M1, M2, and C controllers for redundant control. In simplex control, only the M1 controller is connected. Six customer-supplied auxiliary contact inputs are powered and monitored by ECTB using 70 V dc from plugs J13M1 and J13M2 are resistor-isolated and supplied to the contacts. The wetting voltage can vary from 63 to 84 V dc. The state of the contact is monitored. The resulting signal drives a red indicating LED, and fans out to M1, M2, and C. One contact from 52G is monitored using the 70 V dc excitation in the same way as the auxiliary inputs. The status is indicated with a red LED. One contact from 86G is wetted with a nominal 70 V dc as above. The state of the contact is monitored by controllers M1, M2, and C. APPLICATION DATA: K1 and K2 are the trip relays in controllers M1, M2, and C. K1GP through K4GP are the general-purpose relays. Terminal blocks TB1 and TB2 are held down with two screws and can be removed. Three 25-pin sub-D connectors, J405, J408, and J415 are for cables to the EBKP backplane for connection to the EMIO boards M1, M2, and C. Plugs J13M1 and J13M2 bring in 70 V dc for contact wetting from the M1 and M2 power supplies.
