Part overview and fit
The ABB AI561 (1TNE968902R1101) is a 4-channel analog input module accepting voltage or current signals, with 12-bit resolution. Pluggable screw terminals keep field wiring changes clean. The IP20 housing suits clean, dry cabinet environments. Operating range is 0 to +60 °C ambient, no derating requirement noted within that band. If your cabinet runs hotter than 60 °C, this module needs forced air or a cooler location.
Pluggable terminal blocks — pull the connector, land sensor wires, then push back onto the module. Saves time during panel build or swap-out. No backplane wiring to disturb. IP20 housing means no protection against moisture or dust ingress inside the enclosure. Mount only in a cabinet rated IP54 or better. Ambient operating limits 0–60 °C cover most control rooms; avoid placing directly above a heat source like a transformer or VFD.
