| | | |
| | | Input / Output Connections Digital Inputs The 16 potential-free digital inputs of the UCW-24/28IO/50 are divided over ports A and B into groups of 4 inputs each, each with a common return terminal "C". The inputs may be in any polarity, with a voltage range of 12 to 24 VDC. If the "C" terminal of a group is connected to GND, the separate digital input signals in that group of 4 would be at +12 to +24 VDC, and vice versa for reverse polarity. When an input is activated, the corresponding LED lights up. | | |

| | | Digital Outputs The eight digital outputs C0....C7 (Port C) are switched by PNP transistors, with floating emitter-collector terminals. Power for digital outputs must therefore be supplied from an external source. Each output can switch a load of 500 mA, maximum. When an output is switched on, its corresponding LED lights up. The + and - lines of the power supply for energizing the digital outputs (9 to 30 VDC) must be connected, respectively, to the + and - terminals of the digital output terminals group. The individual digital outputs lines are of +ve polarity (when switched on). | | |

| | | Analog Inputs (Model UCW-28IO/50) The four isolated analog inputs of Model UCW-28IO/50, grouped in Port D, accept current loop signals in the range 0-20 mA. Each input has 2 connecting terminals (+ and -). Use only shielded twisted-pair cables for analog input signals. Analog signal cables should be kept as short as possible, and should not be routed near power cables. | | |

| | | Caution! Only twisted cables should be used for carrying analog input signals, and these should be kept as short as possible! | | |
