TM3DI16 - Modicon TM3 Discrete Input Module, 16 Inputs, 24 V DC, Screw Terminal
The TM3DI16 is a discrete input module from the Modicon TM3 range of expansion I/O, designed to add digital input capacity to Modicon M221, M241, M251 and M262 logic controllers. It provides 16 inputs in a single module that mounts on TH35-15 or TH35-7.5 DIN rail to IEC 60715, or on a plate or panel with a fixing kit.
Each of the 16 inputs accepts 24 V DC and conforms to IEC 61131-2 Type 3. Voltage state 1 is guaranteed from 15 to 28.8 V DC and state 0 from 0 to 5 V DC. The input logic is sink or source (positive/negative). Input current is 7 mA at an input impedance of 3.4 kOhm, with a maximum response time of 4 ms on turn-on and 4 ms on turn-off. Isolation between the input channels and the internal bus is 500 V AC.
Field wiring uses removable screw terminal blocks on a 3.81 mm pitch, accepting 0.14 to 1.5 mm² (26 to 16 AWG) solid conductors. The terminal blocks are removable. A green LED on each channel indicates input status. The module is powered from the controller bus and draws 40 mA at 5 V DC with all inputs on, 5 mA with all inputs off, and 0 mA at 24 V DC in either state.
The housing is IP20 rated and measures 90 mm in height, 27.4 mm in width and 84.6 mm in depth, with a net weight of 0.1 kg. Modules use a simple interlocking assembly mechanism. Operating ambient temperature is -10 to 55 °C for horizontal installation and -10 to 35 °C for vertical installation, storage from -25 to 70 °C, relative humidity 10 to 95 % without condensation, operating altitude up to 2000 m.
The module meets IEC 61131-2 and IEC 61010-2-201, is marked CE, and carries cULus, UKCA, RCM and EAC certification. MTBF is 250 years at 40 °C. Country of origin: Taiwan.
