TAC System 8000 Eight-Stage Sequencer Controller

Model Chart

Specifications

This controller is an electronic linear sequencer for

sequencing external low or line voltage contactors

or other loads. This unit also has a 2-15 Vdc

proportional output for use with other controlled

devices.

Features:

• Dual sensing input capability.

• 2 to 15 volt control signal for additional functions.

• Can be adapted to competitive 135 Ω controllers.

• Power demand input for load shedding ability.

• Proportioning output signal to afford proportional control

between on-off stages.

• Self-contained UL/CSA approved wiring package.

Model No.
