Logic Power Supply Parameters
Nominal input voltage: 24 VDC
Permissible operating voltage range: 22 VDC ~ 26 VDC
Typical steady-state operating current: 0.6 A
Maximum peak inrush current at power-on: 1.2 A
Power is fed from external EXTB or ESPM interface modules. Unstable supply voltage may result in irregular SCR triggering.
On-board Internal Power Conversion
This module converts the incoming 24 VDC logic power into internal auxiliary power supplies to feed drive and sensing circuits.
Internal auxiliary output voltages: 15 VDC and 5 VDC
Max. load current for the 15 VDC auxiliary circuit: 350 mA
Max. load current for the 5 VDC auxiliary circuit: 200 mA
Electrical Ratings of Control Input Signals
Digital control command input levels:
High-level threshold: 18 VDC ~ 26 VDC
Low-level threshold: 0 VDC ~ 5 VDC
Typical sink current of each digital input channel: 8 mA
Input signals receive de-excitation enable instructions from EMIO and EXTB control boards.
Drive and Feedback Output Performance
SCR gate trigger output voltage: 9 VDC ~ 12 VDC
Typical gate trigger pulse current: 40 mA
Conduction feedback output: 0–24 VDC digital status signal
Maximum continuous load current for feedback terminals: 100 mA
Electrical Limits Related to SCR De-Excitation Circuit
Breakover trigger voltage of the automatic overvoltage protection circuit: 320 VDC
This control board cannot withstand high field current directly. It only outputs firing pulses to external power SCRs. Field discharge current is processed by the power stage assembly rather than this circuit board.
Electrical Protection Specifications
Built-in reverse polarity protection for the 24 VDC main power input
Overcurrent protection threshold of internal auxiliary circuits: 450 mA
Capable of enduring short-time transient voltage surges up to 40 VDC
Sustained voltage above 28 VDC will activate internal protection lockout.
Conduct visual inspection to check board integrity, connectors and jumper settings; confirm no mechanical damage.
Verify all wiring connections according to drawings, check for short circuits and reversed polarity.
Power on the EX2100 system and measure 24 VDC input supply voltage to the IS200EDEXG1B.
Confirm internal 5 VDC and 15 VDC auxiliary power rails work within normal range.
Check communication and command signal exchange between IS200EDEXG1B, EXTB and EMIO boards.
Simulate de-excitation enable command and measure SCR gate trigger output signals.
Verify conduction feedback signal output responds correctly after SCR triggering.
Perform overvoltage protection function test to confirm threshold operates as designed.
Run no-load system linkage test to check complete de-excitation logic sequence.
Record all measured parameters, clear faults and confirm stable standby status.
