The TM171ALON: Status indication is handled by two front-panel LEDs: red for service and green for network status — no need to break out auxiliary contacts for basic diagnostics.
Integration facts
IP20 rated — suitable for dry indoor cabinets. 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.
