Communication SPD (for communication/signal) HF series
Showden Co., Ltd.
About This Product
■Summary
The ASG series is used in combination with an ASG-SPD unit with fault indication and a dedicated power supply unit/alarm unit (and surge counter unit). This is an SPD failure monitoring system that transmits the SPD failure status from the SPD installation location (on-site) to a remote monitoring system.
■Fault display function
By connecting the dedicated power supply unit and alarm unit, the SPD failure status can be displayed on the front LED lamp. Additionally, faults can be output via contact and can be sent to a distant monitoring system.
■Excellent protection circuit mechanism
We offer protection circuit types suitable for the circuits to be protected (communications, signals, instrumentation, etc.). In addition, the fault contact output circuit and power input circuit (alarm unit) are equipped with protection circuits as standard, so there is no need to install a separate SPD for the alarm circuit or SPD for the power circuit.
■Complete range of anti-ground noise countermeasure products
ASZ-Z series (noise-resistant connection) and ASG-HF type are available as anti-ground noise countermeasure products.
■Features
・The number of protection fibers per SPD is large, contributing to space saving (4 to 5 cores)
・Compliant with JISC5381-21 categories C2 and D1
- Standard protection circuit for instrumentation and signal SPDs, suitable for weak current signals up to DC200mA.
・Equipped with GDT between grounding, ABD between lines, and line resistance, making it especially excellent for protection between lines.
・It has the feature of not allowing high frequency noise such as inverter noise generated between the signal line and the ground to pass through the line.
■Notes
- If the withstand voltage to ground of the device to be protected is particularly low (for example, if there is a low voltage circuit such as an IC between the device and the ground), we recommend the HS series.
・If there is a risk of the SPD malfunctioning due to ground-to-ground noise occurring in the communication or signal line to be protected, we recommend the HF series.
■Failure display
・Normal: LED (red) off
・During deterioration/failure: LED (red) lights up
■Alarm contact output
・Contact terminal: ASG-AL terminal A, B, C
・Contact specifications: 1C contact
・Contact rating: AC220V 1A, DC110V 0.5A
■Connection terminal
M3 screw terminal (for round crimp terminal M3 slim) Maximum width of compatible round crimp terminal: 6.0 mm or less
■Applicable wire
・Single wire: 0.35~1.82mm2
・Twisted wire: 0.2~2.63mm2
・AWG: 26 to 14 wires are crimped to M3 crimp terminals (M3 slim for stranded wire 2mm2) and wired.
