Integrator's quick read
The 6AG1326-2BF41-2AY0: Temperature range follows EN 50155 T1: -25 to +55 °C ambient during regular operation; Tmax listed as 60 °C. Current derates from 5 A at 40 °C to 4 A at 60 °C, so consider grouping and ventilation. Module measures 80 x 125 x 120 mm (W x H x D), about 465 g. Isolation tested at 500 V AC between channels and backplane bus; channels grouped in groups of four with full isolation between groups.
DIN-rail mount, 40-pin front connector required — pick a compatible base unit (ET 200MP or ET 200SP depending on system). Width of 80 mm occupies a standard module slot. Switching frequencies: resistive load max 30 Hz, inductive load max 2 Hz, lamp load max 10 Hz. For pure resistive loads and good ventilation, count on 5 A per channel up to 40 °C; above that, drop to 4 A. Reverse polarity protection is not provided, so check the 24 V DC supply polarity (2L+, 3L+). Off-state leakage max 0.5 mA per channel. Power loss typ. 12 W — factor that into cabinet cooling.
