Solid State Relays (SSRs) are broadly defined as automated switching circuits used in the control of devices by a portion of the same circuit or a separate control circuit. They are designed with a variety of switching, control, feedback and power supply voltages. TheXBA170P is an example of such a device and this paper shall examine its application field, as well as its working principle.

The XBA170P is a 25A solid state relay, housed in a compact IP00 rated enclosure rated for up to 150 degrees Celsius operation. It is made up of a thick film board with a contact forming bridge, a highly durable static contact, a strong load current, as well as a signal switching element integrated circuit from two sources. It is able to control low energy loads such as fans, valves and pumps. It is suitable for use in printing, woodworking, textile and other automated production lines, as well as in medical and food production processes.

The working principle of the XBA170P is quite simple. It features a built-in optically-isolated MOSFET switch, which is activated when power is supplied to the control port. This causes a current to flow through the bridge, forming a conductive path between the load and the control port, completing the circuit between the two points. Once the current reaches the specified level, the load is turned on. When the power is then removed from the control port, the bridge reverts to its original path, turning the load off.

The XBA170P also features a built-in failsafe capability. This ensures that, should the device become disconnected or the control port fail, the load will still remain off. This is a useful feature for systems where a power outage could potentially cause injury or damage. Additionally, the XBA170P has a test mode which can be used to check that the device is working properly, prior to connecting it to its intended load.

In summary, the XBA170P is a solid state relay used to control low energy loads, such as fans and pumps. It is housed in a compact, IP00-rated enclosure, and is capable of operating at temperatures up to 150 degrees Celsius. In addition, the XBA170P features a built-in opto-isolated MOSFET switch, as well as a failsafe function, allowing for safe and reliable operation. Furthermore, the device also features a test mode, allowing users to ensure that the device is working correctly before connecting it to its intended load.
