CHM1DIU Datasheet, PDF (7/12 Pages) Cooper Bussmann, Inc. – Compact Modular Fuse Holders With the Industry’s Best Ratings

Remote Fuse Monitoring Accessory CH-PLC
Make it Simple with
Cooper Bussmann resettable
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)
- 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
• Rated Impulse Voltage: 8kV
• Local Indication: Two distinct LEDs indicate unit power (green)
and open fuse (red). Upon the replacement of the fuse, the
actuation of the reset switch will reset the open
fuse LED
• Flammability Rating: UL 94V0
Wiring:
• For power, signal and ground connections use 22-24AWG
(0.25mm²) 300V rated wire
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, signal
and ground connections
Minimum Circuit Voltage:
• Minimum circuit voltage required across the CH holder is 100Vac
for the remote indication device to operate
Installation Technique:
• Mounts on the left side of the fuse holder and mechanically
interlocks with the fuse holder switch handle with hardware
provided
IP20 Rating: Yes
Environmental Data:
• Storage and Operating Temperature: -20°C to 75°C
Agency Information:
• UL 508
• cULus to CSA Standard 22.2 No.14
PLC Programming:
• The CH-PLC signal line is designed to provide a digital input to a
PLC I/O card.
• Programmable Logic Control program must be written to properly
interpret the input signal to the PLC.
• The PLC program should check for consecutive high signals
before taking action on a critical process.
De-energize all circuits before installing or removing any CH-PLC devices and follow all prescribed safety procedures.
