Specifications: Parameter Specification Product Range Modicon TM3 (Distributed I/O) Device Type Discrete Mixed I/O Module (Digital Inputs + Relay Outputs) Compatible System Modicon TM3 distributed I/O system (connects via TM3C bus to a TM3 bus controller, e.g., TM3C bus module for Modicon M251 PLC). Digital Inputs 12 inputs, 24V DC (sink/source, PNP/NPN compatible). Input Current Typically 4-6 mA per point. Relay Outputs 8 outputs, Relay contacts (SPDT - Single Pole Double Throw / changeover). Output Contact Rating Typically 2 A @ 250V AC or 30V DC (resistive load). Output Groups The 8 relays may be divided into groups with separate commons (e.g., 4 groups of 2). Verify datasheet for grouping. Isolation Optical isolation for inputs, relay isolation for outputs. Isolation between groups and field/bus. Power Supply Requires 24V DC field power for input circuits and relay coils. Communicates via the separate TM3C bus. Status Indication LED per channel for input status and output state. Connection Removable screw terminal blocks. Mounting DIN Rail (35mm) Operating Temperature 0°C to +55°C (standard industrial range). Standards & Approvals CE, UL, CSA, RoHS, IEC 61131-2.
