GE IC670MDL241B Input Module, 16 Points, 2 groups 240 VAC

In SCT/PPT regulator and dc rotary exciter regulator applications,

the EX2100e regulator system can reduce the effects of exciter time constants.

It combines direct measurement of the generator excitation voltage and excitation current to improve response to system transients.

The architecture is a single control with a single power control module (PCM) or dual control with dual PCMs,

and includes a customer interface subsystem, optional diagnostic local operator interface (touch screen),

optional control operator interface (COI) remote touch screen interface, control power input module, and PCM.

The PCM consists of a bridge interface subsystem, power bridge, optional AC and DC filtering networks,

and AC (ac) and/or DC isolation devices. 

To expand input and output (I/O) capabilities, VersaMax® or Mark* VIe Control IONet I/O modules can be added.

The 151X1235DB15SA03 EX2100e regulator system is available in multiple configurations to

provide control flexibility for thyristor and regulator systems.

For small regulator systems, two pulse width modulation (PWM) power converter modules

use insulated gate bipolar transistors (IGBTs) to provide up to 35 A or 120 A nominal output.

These systems can support the following applications:

• Saturated current transformer/power voltage transformer (SCT/PPT) regulators

• Brushless exciter regulators

• Direct current (dc) rotary exciter regulators
