The PV (process value) display is 13 mm, the SV (set value) display is 11 mm — both readable from a few steps back on a machine panel. The input filter is settable from 0 to 900.0 seconds in 0.5-second steps as a first-order lag filter, which means you can dampen a noisy thermocouple or 4-20 mA signal right in the controller without adding an external signal conditioner. Input impedance is 1 MΩ or more for thermocouple, 450 kΩ or more for voltage, and 250 Ω (external resistor) for current — standard values that match most industrial sensors without signal degradation.
Certifications and compliance
Carries UL (UL873) and CSA (C22.2 No.24-93) approvals for North American panels, plus CE marking for LVD (EN61010-1) and EMC (EN61326-1). The CE EMC note says it's not available on the 72x72 mm size variant, but this is the standard form factor. Dielectric strength is tested at 1500 V AC for 1 minute between power supply and ground, with insulation resistance of 20 MΩ or more at 500 V DC — solid isolation for a control panel environment.
