Document Type and Number:
WIPO Patent Application WO/2019/200847
Kind Code:
A1
Abstract:
An expandable standard general PEDC logic module, comprising a logic module and an output module. The logic module has a first relay, a second relay, a third relay and a fourth relay, so as to respectively correspond to an operation permission command EN, an operation permission excision command N-EN, a door opening command OP and a door closing command CL, wherein the first relay, the second relay, the third relay and the fourth relay respectively comprise a coil, a normally closed contact and a normally open contact; the operation permission command EN is connected to the coil of the first relay by means of the normally closed contact of the second relay, and the other end of the coil of the first relay is connected to a power source VCC; the operation permission excision command N-EN is connected to the coil of the second relay, and the other end of the coil of the second relay is connected to the power source VCC; the door opening command OP is connected to the coil of the third relay by means of the normally closed contact of the fourth relay; and the door closing command CL is connected to the coil of the fourth relay.
