Product details

The TM3DM8RG is a 4-input/4-relay-output discrete I/O module in the Modicon TM3 compact range. Though powered from the internal backplane bus, it handles sink or source wiring on the input side and provides relay outputs rated 2 A for 24 V AC or 240 V DC loads. Its 27.4 mm width (1.08 in) and spring-cage terminals with 5.08 mm pitch save DIN rail space and reduce wiring time on a panel line.

Input & output thresholds

Input state threshold: voltage below 5 V guarantees state 0; above 15 V guarantees state 1. Input current at state 1 is 7 mA typical. On the output side, the relay contacts require a minimum of 10 mA at 5 V DC to keep the contact film pierced—something to watch when switching dry contacts or low-power indicators.

The module mounts on TH35-15 or TH35-7.5 DIN rail (IEC 60715) or panel with fixing kit, uses a spring terminal block accepting 0.2–2.5 mm² (AWG 24–14) solid or stranded wire, and is IP20 rated for pollution degree 2.
