Front-Mount Auxiliary Contact Blocks

Front-mount auxiliary contact blocks clip onto front face of relay. Contact Rating: A600, Q600.

Side-Mount Auxiliary Contact Blocks

Side-mount auxiliary contact blocks can be mounted on either left or right sides of relay. Positive displacement contacts are designed to prevent simultaneous closing of NO and NC contacts to avoid overlapping between opposing functions. Contact Rating: A600, Q600.

Pneumatic Timer

Pneumatic timers are adjustable time-delayed auxiliary contacts. They come equipped with two time-delayed contacts: 1NO and 1NC, electrically isolated. Setting is scaled over a 350° rotation by means of a knurled knob with timing guide marks. To mount a pneumatic timer, simply clip it on front face of contactor. Contact Rating: A600, Q600.

Surge Suppressor

For suppression of disturbances in circuit voltage occurring upon opening of the relay. Mounts directly on the top of the coil.

Mechanical Latch Block

Mechanical latch block is used to convert a standard relay into a latched relay. Easy to mount, it clips onto front face of contactor. Contact Rating: A600, Q600.

Timers

Time-on delay and time-off delay modules for sequencing control of contactors. They deliver high repeatability, +/-3% in ambient temperatures from 32° to 104°F. A red LED provides indication during time-delay operation.

Interface Modules

Interface modules allow relay operation from 24 Volt or 48 Volt sources (such as a PLC output). Current consumption is 15 mA @ 24 Vdc and 25 mA @ 48 Vdc. A red LED provides indication when voltage is applied to E1-E2.

Auto-Manual-Stop Modules

Auto-Manual-Stop modules allow local and/or remote operation of the relay coil. The Auto-Manual switch selects the input connected to the coil circuit-A1 for automatic or remote operation, B1 for local operation. In both connections, the manual On-Off switch is in series and controls power to the coil. Auto-Manual can be switched only when the On-Off switch is in the Off position. A red LED provides indication when the coil is energized.

Voltage Surge Suppressors

Voltage surge suppressors plug into timer, interface, or auto-stop-manual modules.
