Remote Fuse Monitoring Accessory CH-PLC

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

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.
