PURPOSE:To deal efficiently with the needs of user in the design and manufacture of control/monitor board of multi-functional specification and to save manpower in replacing and wiring works of current transformer required by modification of rating. CONSTITUTION:The control/monitor board is unitized by collecting and standardizing common terms of each function at an operation monitoring section including an operation panel, 8 control section including control sequences, and a terminal section for externally connecting control object machines, wherein each of more than one system corresponding to the control object machine 11 comprises an operation monitoring unit 8, a control unit 9, and a terminal unit 10 connected through connector cables 13, 14, 15. Each system is provided with a current transformer 6 having a rating switching resistor network with secondary current thereof being set below 10mA. |
