Power Supply
20 to 48 VDC allowed, max. 12W
Power over Ethernet (IEEE 802.3af)
Digital Input (External Trigger / Hold)
Galvanically isolated TTL input signal (digital active low)
To trigger:
-
Average-, Peak-, Valley Hold function
- Restart of signal postprocessing
- Switching the optional LASER sighting on/off
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:
-
NO = Normally Open
- NC = Normally Close
- PO = Permanently Open
- PC = Permanently Close
Analog Input (0/4
– 20mA current loop input)
Galvanically isolated analog input signal, to read in the current (0/4
– 20mA),
given by an external device like PLC, Computer or any kind of process control
device. The internal loop resistor per pyrometer
is about 220Ω.
Via a controlled current from an external device you are able to set/correct:
-
Verification of preset current values, given by external devices
- Set emissivity (1-Color or 2-Color mode)
- Set slope (2-Color devices only)
- Set background temperature for background compensation
Analog Output (current loop, 0/4
– 20mA)
Galvanically isolated analog output signal, to stimulate output currents in the
range (0/4 - 20 mA). The output signal is an active output with 16 Bit
resolution, to drive a maximum resistive load of 500Ω. Just the acquired
object temperature, measured by either 1C or 2C devices, displayed on on
the Endurance® control panel, is converted to a 16 bit current equivalent. The
user has to define the temperature measurement range and must assign the
lower and upper range limits to the current equivalent (0
– 20mA / 4 – 20mA).
RS485 Serial Communication Interface (4-/2-wire full/half duplex transmission)
Galvanically isolated 4- or 2-wire RS485 communication interface. The
ordered 'Electronics Enclosure Configuration' option (M16-connector/Cable
gland) determines the 4-/2-wire capability.
