    For proper operation care has to be taken with regard to power supply concept and design. Due to space restrictions the TMCM-1140 includes about 40µF/35V of supply filter capacitors. These are ceramic capacitors which have been selected for high reliability and long life time. The module includes a 28V suppressor diode for over-voltage protection.

    3.3.2.1 Digital Inputs IN_1, IN_2, IN_3 The eight pin connector of the TMCM-1140 provides three multipurpose digital inputs IN_1, IN_2 and IN_3. All three inputs accept up to +24V (nom.) input signals and offer the same input circuit with voltage resistor dividers, limiting diodes against over- and under-voltage and programmable 2k2 pull-up resistors.

    0 and 1) will be at approx. +5V input voltage (half the analog input range). 3.3.2.3 Outputs OUT_0, OUT_1 The eight pin connector of the TMCM-1140 offers two general purpose outputs OUT_0 and OUT_1. OUT_0 is an open-drain output capable of switching (sinking) up to 1A. The output of the N-channel MOSFET transistors is connected to a freewheeling diode for protection against voltage spikes especially from inductive loads (relais etc.) above supply voltage (see figure below).
