Specifications External Device I/O Terminals You can use Input/Output external devices together with the Multi-Terminal Module VB-EX50. External Device Input Terminals (IN+, IN-) The external device input terminals consist of 2 terminals (IN+, IN-). The '-' terminal is grounded on the inside of the main unit. By connecting 2 cables to the + and '-' terminals and then electrically short-circuiting across the terminals (ON) or separating the connection (OFF), an interrupt can be generated for the internal controller. See "Schedule Setting Tool" in Chapter 4 "VB Administration Tools" (→ P.4-27) for information on the settings. Connect any sensors and switches to terminals with electrically separate GND terminals and power supplies. External Device Output Terminals (OUT A, OUT B, OUT C) The external device output terminals consist of 3 terminals (OUT A, OUT B, OUT C). There is no distinction between "+" and "-" with OUT A, OUT B and OUT C. The Internal controller switches the 2 output terminals to disconnected or connected condition. The output terminals use photo couplers and are separate from the internal circuit in the VB-C50i/VB-C50iR. * External input status can be checked and external output status can be controlled using Admin Viewer (→ P.4-66). Loads connected to the output terminals should be within the following ratings: Rating across the output terminals: Up to 50 V DC Continuous load current: 100 mA or less Internal Connection Chart 10kΩ 10kΩ 0.1µF +3.3V 10kΩ + Input terminals IN+, IN- - Output terminals OUT A, OUT B, OUT C Appendix Internal controller You need the Multi-Terminal Module VB-EX50 (→ P.1-12) to set input/output external Tip device. 7-17
