Depending on the selected modules, interaction with:

• Module IN6I(24V) – six analog inputs with standard current loop output 0-20mA or 4-20mA powered from internal 24 VDC
• Module IN6I– six analog inputs with standard current loop output 0-20mA or 4-20mA (or passive transmitters with external power supply)
• Module IN6RTD– six analog inputs for connection temperature RTD sensors type Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, Cu50, Cu53, Cu100, KTY81, KTY83, KTY84; transducers with an output resistance in range 0 .. 4700 Ω
• Module IN6TC – six analog inputs for connecting thermocouples type J, L, K, U, E, N, B, R, i S
• Module IN3 – three universal analog inputs, enabling the connection of transducers as standard 0/4-20mA, 0/2-10 V, 0/1-5 V or temperature sensors  RTD, TC and  linear measurement of the resistance 0 .. 4000 Ω or voltage -140..+140 mV
• Module IN6D – six PULS inputs ability to work in a state mode, frequency measurement mode or pulse counting
• Module IN2RS485(24V) – two independent and galvanically separated RS485 ports for reading transducers or other devices operating in the Modbus RTU standard; extra 24VDC voltage source power supply for external transducers
• Module IN2RS485 – two independent and galvanically separated RS485 ports for reading transducers or other devices operating in the Modbus RTU standard
• Module 1HRT – one HART (4-20 mA) port with the possibility of powering transmitters, operating in the Primary Master mode or in the Secondary Master mode
• Module OUT6RL – six semiconducting output relays rated at 24 VAC / 0,5 A or 36 VDC /0,5 A
• Module OUT3 – three programmable analog outputs 0/4-20mA, 0/1-5 V, 0/2-10 V
• Module PSBATT – supplying the device with NiMH storage batteries in the event of voltage break (backup) or periodic operation with battery power supply (from 1 to 20 hours depending on the configuration)

• ca. 2 years of estimated recording time for recording speed every 5 s for 16 measuring channels.
• Recording to internal 2GB memory
• Checksum secured files – protection against result errors
• Recording frequency for main archive between2 sand 24 h; define two recording frequencies. toggled upon exceeding the set alarm thresholds
• Recording frequency for totalizers archive between 1 min and 24

No buttons present, programming/use is via touchscreen.
