Electrical Specifications
Digital Input (External Trigger / Hold)
Galvanically isolated input signal (digital active low) to trigger:
• Average Hold / Peak Hold / Valley Hold function, to restart signal postprocessing
• LED / Laser / Camera on/off
Analog Input (0/4 – 20mA current loop input)
Galvanically isolated analog input signal, to measure the current (0/4 – 20mA), given by an
external device like PLC, Computer or any kind of process control device. The internal loop
resistor of the Endurance® device is about 220Ω.
Via a controlled current from an external device you are able to set/correct:
• Set current from ext. device and read the current via defined serial command “IN”
• Set emissivity (1-Color or 2-Color mode)
• Set slope (2-Color devices only)
• Set background temperature for background compensation
Digital Output (Relay / Alarm Output)
Galvanically isolated digital output of a potential-free solid-state relay contact. The max.
relay contact load is limited to 48 V, 300 mA. The relay contact behavior is settable via the
user interface or a serial command to operate as following:
