Existing output type relay module, the type requirements of PLC is strict, and the suitability is poor；Have to rely on software when hardware debugging just can carry out；The fault-tolerance of power supply is poor；Institute's matching terminal definition is indefinite, it is easy to wiring error occur, changes inconvenience.Thus more there being the necessity improved.
Utility model content
The purpose of this utility model is in that to provide a kind of output relay module, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of output relay module, including circuit board support and the circuit board being arranged on circuit board support, described circuit board is provided with DB joint, power supply terminal, non-return diode, forces button, relay and control terminal；Described relay is arranged on relay base, and relay base welds on circuit boards, and coil one end of relay is connected with DB union line；The contact of described relay is respectively led on control terminal；Described control terminal identifies labelling respectively through terminal；The coil of described relay is in parallel with non-return diode and status indicator lamp, and is linked on the inlet wire port forcing button；The outlet port of described pressure button is connected on DB joint；Described circuit board is powered by power supply terminal and external power supply.
Preferably, described relay is inserted on the shell fragment of relay base by pin, is suitable for the relay of plurality of specifications.
Compared with prior art, the beneficial effects of the utility model are:
(1) this output relay module, on output relay module, each relay is provided with forcing button and status indicator lamp；Force button for can force to allow the actuating of relay when PLC does not export, corresponding display lamp can be had when each actuating of relay bright, client is facilitated to check operating state, the correctness of device and circuit just can be tested when not having software to connect, it is no longer dependent on software debugging, improves work efficiency；Force button and display lamp can the quality of test relay at any time, do not rely on software, debugging is convenient.
(2) this output relay module, in relay coil side added with non-return diode, can reduce the impact of big electric current on the one hand, extend the service life of relay, be possible to prevent the incorrect polarity of power supply to access on the other hand；Non-return diode can protect electric power polarity, it is prevented that the impact to PLC of the instantaneous electric current of make-and-break.
(3) this output relay module, the welding of relay base, it is possible to plug relay head is convenient for changing.Damage to device when additionally also reducing welding；Control terminal mark is clearly, it is possible to differentiate position clearly, improves the accuracy of wiring；Relay power polarity common port is optional simultaneously.
