Industrial Control and Power Interface
The IS200EPSMG1A receives a nominal 125 VDC input and converts the incoming supply into the specified +5 VDC rail at up to 6 A. This power path supports the electrical requirements of the associated EX2100 hardware.
The module also provides an isolated contact-wetting output of +70 VDC at 0.2 A. Therefore, the input and output sides maintain electrical isolation rated at 2.5 kVAC.
The specified efficiency exceeds 85% at 50% load. The operating temperature range extends from -40 deg C to +70 deg C, while storage conditions extend from -45 deg C to +85 deg C.
Frequently Asked Questions
Q: What input voltage does the IS200EPSMG1A accept?
A: The module accepts 125 VDC with a specified tolerance of +/-10%.
Q: What output does the IS200EPSMG1A provide?
A: It provides a +5 VDC output rail rated at 6 A, plus an isolated +70 VDC contact-wetting output rated at 0.2 A.
Q: What isolation rating does the module specify?
A: The specified input-to-output isolation rating is 2.5 kVAC.
Field Installation Guidelines
- Verify the module model and electrical ratings before installation.
- Confirm that the available DC supply matches the specified 125 VDC input range.
- Maintain correct polarity and secure all power connections according to the applicable GE EX2100 installation documentation.
- Route power wiring separately from low-level signal wiring where practical to reduce electrical interference.
- Keep conductive debris, loose hardware, and contamination away from the PCB and its connectors.
- Ensure the installation environment remains within the specified -40 deg C to +70 deg C operating range and 95% RH non-condensing humidity limit.
- Provide adequate ventilation around the assembly so heat can dissipate under load.
- Do not apply voltage to the module until the wiring, connector seating, and supply polarity have been verified.
