Panel Mount Adapter Plates

Panel mount adapter plates for panel mount controllers and control panels provide a convenient, cost saving solution to modify existing control panels. Available in a variety of DIN sizes, adapter plates make changing out old, larger size temperature controllers with more sophisticated, compact controllers easy. Simply complete the build-a-part with the specifications you require.

Serial Converters

Serial Converters

 (3)
Laptop and personal computers include a variety of features including serial communications "COM" ports and Universal Serial Bus (USB) ports that allow them to communicate with other devices such as printers and digital cameras. Industrial and commercial devices such as process and temperature controllers often have EIA 485 communications interfaces (also known as RS-485) which cannot be directly connected to a typical computer. Watlow® offers a series of serial converters that provide a simple and reliable solution to connecting these devices to computers.

These compact serial converters offer several features that make them ideal for use in applications in which Watlow controllers communicate with a computer via Modbus® RTU or ...


Fuses and Fuse Holders

Semiconductor Fuses

 (9)
For protection of solid state power controllers, such as Watlow's DIN-A-MITE®, a semiconductor fuse is recommended to protect the power controller and ensure long life. To safeguard power controllers, Watlow offers DIN-rail mount fuse holders and semiconductor fuses in various sizes to accommodate the entire DIN-A-MITE SCR power controller family and solid state relay products. These fuse holders feature lockout/tagout and open fuse indication.

current-transformer_240

Current Transformers

 (17)
A current transformer (CT) provides a signal that is proportional to and isolated from the load that passes through it. The signal from the CT can be measured by a temperature or power controller. The value from that measurement may be used to trigger an alarm, detect an open heater or a shorted SSR, or to indicate the current. Choose the model that provides a measurable output for the planned load current.

To order, simply identify the desired part number. Contact your Watlow representative for availability.


arc-supressor_240

Arc Suppression and EMI Filters

 (5)
These accessory components are used with Watlow® temperature and process controllers and power controllers to reduce the effects of electromagnetic interference (EMI) and electromagnetic noise. Arc suppression devices are used to protect controller outputs when inductive loads are controlled. EMI filters are used in applications that must meet CE requirements to remove noise associated with operating power controllers.

Power Supplies

Power Supplies

 (3)
Watlow’s series of Class 2, low-profile DIN rail-mount power supplies, only 2.2 inches deep, are ideal for shallow enclosure installations commonly used in building automation and security applications.

The DSP series supplies are available with nominal outputs from 20 to 28 volts and power levels ranging from 31 to 91 watts in three package sizes. Load regulation is less than 1 percent from no load to full load, with ripple and noise below 50 millivolts. To compensate for cable voltage drops, output voltage can be adjusted from the front panel and colored LED indicators immediately confirm the output status.

DFJ Fuses

DFJ Fuses

 (7)
Protect Branch Circuits and Solid State Power Controllers With One Fuse

To meet national and local electrical code requirements for branch circuit protection and to protect solid state power controllers, such as Watlow’s DIN-A-MITE®, a DFJ fuse is recommended. Watlow® offers fast-acting DFJ fuses and holders in amperage ratings covering the range of load currents appropriate for use with the entire DIN-A-MITE power controller and EZ-ZONE® ST integrated controller families.

DFJ fuses protect personnel from injury, protect equipment from damage and are required to minimize damage in the event of a short circuit and achieve short circuit current ratings for Watlow DIN-A-MITE power controllers and EZ-ZONE ST controllers.
