TM2DDI16DT - Modicon TM2 Discrete Input Module, 16 Inputs, 24 V DC, Screw Terminal

Product type: I/O Expansion Module  |  Range: Modicon TM2  |  Connection: Removable Screw Terminal Block

The TM2DDI16DT is a discrete input expansion module from the Modicon TM2 range, designed for Modicon M238 logic controllers and also compatible with Twido controllers and Advantys OTB interface modules. It provides 16 input channels on a single module that mounts on a 35 mm symmetrical DIN rail, or on a plate or panel surface using the mounting holes, and connects to the controller through the expansion bus.

Each input accepts 24 V DC over a range of 20.4 to 28.8 V DC and conforms to IEC 61131-2 Type 1. Input logic is sink or source (positive or negative), selected by wiring, and both wiring methods are supported on the same module. Input current is 7 mA at an input impedance of 3.4 kOhm. The OFF state is guaranteed below 5 V DC, and the ON state above 15 V DC with a current above 2 mA. Turn-on and turn-off time are 4 ms each. Isolation between the inputs and the internal bus is rated 500 V AC for 1 minute; the input terminals are not isolated from each other.

All 16 channels share a single common point, and the COM terminals of the terminal block are connected together internally, so the common has to be wired only once. Field connection is made on one removable screw terminal block, which can be unplugged for replacement without touching the wiring; the connector is rated for more than 100 insertion and removal cycles. A display block on the front face indicates input status. The module is powered from the controller bus and draws 40 mA at 5 V DC with all inputs on and 5 mA at 5 V DC with all inputs off, with no consumption on the 24 V DC bus.

The housing is IP20 rated, measures 90 mm in height, 23.5 mm in width and 84.6 mm in depth, and weighs 0.065 kg net. Allow an extra 8.5 mm of depth when the DIN rail clamp is pulled out. Operating ambient temperature is 0 to 55 °C, storage from −25 to 70 °C, relative humidity 10 to 95 % without condensation, operating altitude up to 2000 m and storage altitude up to 3000 m, pollution degree 2 to IEC 60664.

The module is resistant to vibration of 3.5 mm amplitude from 5 to 8.5 Hz and 1 g constant acceleration from 8.5 to 150 Hz when mounted on DIN rail, and to mechanical shock of 15 g for 11 ms. Electromagnetic emission complies with IEC 61000-6-4 Class B; immunity is tested to IEC 61000-4-2, -4-3, -4-4, -4-5, -4-6 and -4-8. Input characteristics conform to IEC 61131-2 Type 1.
