Ambient operating range is 14 to 131 °F (-10 to +55 °C), storage down to -4 °F (-20 °C). 10 to 90 % RH non-condensing. Wiring uses a removable screw terminal block accepting up to 2.5 mm² cable. Pitch is 3.81 mm. The terminal block is removable, so the module can be swapped without disturbing field wiring. Mechanical mounting is via the base board only — no additional DIN-rail clip. The module adds negligible depth beyond the base board, keeping panel layouts tight.","metaTitle":"TM171ALON Modicon M171 LonWorks Module, 78 kbps, IP20","metaDescription":"TM171ALON is an active-production LON communication module for Modicon M171/M172 PLCs.
