Remote Fuse Monitoring Accessory – CH-PLC
UL Class CC, Midget and IEC 10x38 fuses
Description
A resetable three-phase remote fuse monitor that
integrates with a Programmable Logic Controller (PLC) or
other monitoring and control equipment.
Specifications:
• Power Input: 24Vdc / 5mA
• Sensing Voltage: 600V/30mA
• Output Signals: Digital 0Vdc (Low), 24Vdc (High)
• Rated Impulse Voltage: 8kV
• Local Indication: Two distinct LEDs indicate unit power
• Flammability Rating: UL 94V0
Wiring:
• For power, signal and ground connections use 22-24AWG
Emissions and Immunity Testing:
• Electrostatic Discharge IEC 61000-4-2
• Electrical Fast Transient/Burst IEC 6100-4-4
• Surge Immunity IEC61000-4-5
Packaging:
• The CH-PLC is packaged individually
• A single unit monitors up to three phases
• Package includes 0.11” (2.8mm) quick connects for power,
0210
- 0Vdc Low – Fuse is good
- 24Vdc High – Fuse has opened
When the fuse opens, the output signal is sent high and will
remain high until the unit is reset
(green) and open fuse (red). Upon the replacement of the
fuse, the actuation of the reset switch will reset the open
fuse LED
