Frequently asked questions

The ArmorStart LT 290D/291D has a horsepower range of 0.5…5 Hp (0.37…3.3 kW).

The ArmorStart LT 294D has a horsepower range of 0.5…2 Hp (0.37…1.5 kW).

The ArmorStart LT is available with Full Voltage, Full Voltage Reversing, or Variable Speed motor control performance.

The ArmorStart LT has an IP66/UL Type 4/12 enclosure, making it suitable for water washdown environments.

The ArmorStart LT operates on 24V DC control voltage. It can be powered by an internal power supply sourced from the 3-phase line, or an external 24V DC power source.

DeviceLogix is a programmable logic engine built into the ArmorStart LT. It allows for local logic programming without the need for a PLC. DeviceLogix can be used to implement operations such as AND, OR, NOT, Timers, Counters, Latches, and Analog operations. It can run independently of the network or collaboratively with the PLC.

ZIP allows the ArmorStart LT to receive data directly from up to four other DeviceNet nodes without going through a network scanner. This is beneficial for conveyor applications where multiple zones need to communicate with each other.
