DC 24V Power PLC Transistor Module , PLC Negative Control DC Amplifier Board

1 , the load voltage, current type is different

Load type: Transistors can only carry DC loads, while relays can have both AC and DC loads.

Current: Transistor Current 0.2A-0.3A, Relay 2A.

Voltage: The transistor can be connected to 24V DC (generally the maximum is about 30V DC, and the relay can be connected to DC 24V or AC 220V.

2, different load capacity

The ability of a transistor to carry a load is less than the ability of a relay to carry a load. When using a transistor, it is sometimes necessary to add other things to drive large loads (such as relays, solid state relays, etc.).

3, the transistor overload capacity is less than the ability of the relay overload

In general, when there is a large inrush current (for example, light bulbs, inductive loads, etc.), the transistor has less overload capacity and needs to be derated more.

4, transistor response speed faster than the relay

The principle of relay output type is that the CPU drives the relay coil to make the contacts pull in and make the external power supply drive the external load through the closed contacts. The open circuit leakage current is zero and the response time is slow (about 10ms).

Transistor output type principle is the CPU through the optical coupling to make the transistor off, to control the external DC load, the response time is fast (about 0.2ms or even less). Transistor output is generally used for high-speed output, such as servo/stepping, etc., for output with high operating frequency: such as temperature PID control, mainly used in stepping motor control, servo control, and solenoid valve control (high valve operating frequency ).

Transistors are mainly used for positioning control. The output of the crystal is used to emit pulses. The relay cannot be pulsed and it cannot be positioned. If the relay is used to control the positioning servo or stepping, the positioning module must be added, which is not economical. With a single transistor output, servos can be controlled.

5. In the rated working condition, the relay has life cycle times, and the transistor has only aging and no limit on the number of uses.

Because the relay is a mechanical component, it has a long operating life. The transistor is an electronic component. Only the aging is used, and the number of uses is not limited. The number of switches per minute of the relay is also limited, while the transistor is not.

6, the transistor output price slightly more expensive.

Relay output:

AC ------ AC (normal AC 220V) power supply (L1 N)

DC ------ DC (input)

RLY ------- Relay output (output)

Transistor output:

DC ------ DC (normal 24V DC) power supply (L+M)

DC ------(input)

DC ------ (output) such as PLC 224 XP CN DC/DC/DC
