TM3DI8A - Modicon TM3 Discrete Input Module, 8 Inputs, 120 V AC, Screw Terminal
Product type: Discrete Input Module | Range: Modicon TM3 | Country of origin: Taiwan
The TM3DI8A is a discrete input module from the Modicon TM3 range of expansion I/O for Modicon M221, M241, M251 and M262 logic controllers. It provides 8 inputs rated for 120 V AC, on a single module that mounts on TH35-15 or TH35-7.5 rail to IEC 60715, or on a plate or panel with a fixing kit, and connects to the adjacent modules through a simple interlocking assembly mechanism.
Each input accepts 120 V AC and conforms to IEC 61131-2 Type 1. Voltage state 1 is guaranteed from 79 to 132 V and state 0 from 0 to 20 V, with current state 1 guaranteed between 2 and 15 mA and state 0 at 15 mA or below. Because this is an AC input module, there is no sink or source selection to make. Rated input current is 7.5 mA at an input impedance of 11 kOhm. The response time is 25 ms maximum on turn-on and 30 ms maximum on turn-off, which suits 120 V AC control signals but is not intended for high-speed counting. Insulation between the input and the internal logic is rated 1500 V AC, and between input groups 1500 V AC; the inputs are not insulated from each other.
Field connection is made on an 11 x 2.5 mm² removable screw terminal block with 5.08 mm pitch, accepting 0.2 to 2.5 mm² (24 to 14 AWG) solid cable. The COM0 and COM1 terminals are not connected internally, so each common has to be wired separately. A green LED on each channel indicates input status. The module is powered from the controller bus and draws 70 mA at 5 V DC with all inputs on and 25 mA at 5 V DC with all inputs off, with no 24 V DC bus consumption.
The housing is IP20 rated with the protective cover in place, measures 90 mm in height, 27.4 mm in width and 84.6 mm in depth, and weighs 0.085 kg net. 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, pollution degree 2.
The module meets EN/IEC 61131-2 and EN/IEC 61010-2-201, carries CE marking and is certified cULus, UKCA, RCM and EAC. MTBF is rated at 410 years at 40 °C. Country of origin: Taiwan.
