The new DU800 wireless diagnostic unit allows for detector configuration and installation feedback of 8 series detectors on any iOS or Android device. This eliminates the need to adjust any mechanical interfaces once the unit has been installed.
The new slimline, DIN Rail mount housing allows for more physical connections than the traditional relay base and Nortech’s innovative modular design allows for future expansion.
Like its forebears, the 8 series detectors simply work, offering peace of mind in even the most complex installation.
The PD280 supports two loops.
|Self-tuning range:||20μH to 1500μH|
|Sensitivity:||Ranging from 0.01% ΔL/L to 5% ΔL/L
Automatic Sensitivity Boost (ASB) is selectable
|Frequency:||Automatic Frequency Selection (AFS) or select from 6 frequency bands 30-150kHz (Frequency is determined by loop geometry)|
|AFS:||Automatically evaluates all frequency bands on startup and selects the most suitable in the given environment based on signal strength and noise|
|Presence Time:||Permanent or limited selectable|
|Drift Compensation:||Incorporated method of tracking changes caused by environmental conditions at a rate approximating 1% ΔL/L per minute|
|Anti-locking:||Incorporated algorithm accommodates the influence of positive inductance changes to avoid detector lock-up|
|Relay Outputs:||2 programmable relays with NO, NC and COM connections exposed. Options for presence or pulse, pulse on detect, undetect or fault and each relay has configurable Filter, Delay and Extend options|
|Relay Mode:||Relays can be configured to operate as Fail Safe or Fail Secure|
