The module receives power and exchanges I\/O data through the internal TM3 bus connector when assembled with the controller or other TM3 modules.\u003c\/p\u003e\n\u003cp\u003eThe eight inputs support sink or source logic and conform to IEC 61131-2 Type 1 input characteristics. Each channel has an individual green status LED. Isolation between the input circuitry and internal logic is specified at 500 VAC, while the individual input channels are not isolated from one another.\u003c\/p\u003e\n\u003cp\u003eThe module uses a removable screw terminal block with a 5.08 mm pitch.
