The Allen-Bradley 1771-HSN is a PLC 5 IMC 120 servo controller module for high-speed motion applications. It requires a 1771-HM or 1771-HMA memory cartridge to operate. UL listing and CSA certification ensure safety compliance. This module controls axes with a 2 ms update period and handles 250 KHz differential input.
Product Procurement & Buyer Guide
When purchasing the 1771-HSN, you must also buy a plug-in memory cartridge. The module will not function without the 1771-HM or 1771-HMA cartridge. This servo controller fits into one slot of a 1771 I/O chassis. It supports a 120 V fuse voltage and draws 1.7 A from the backplane. The unit measures 3.5 x 6.5 x 2.0 inches and weighs 2.2 lb. It operates in clean industrial environments from 32 to 140 °F. Noncondensing humidity from 5 to 95% is acceptable. The module withstands 30 g operating shock. Procurement managers should verify that the memory cartridge is included in the purchase order. The wiring arms 1771-WA and 1771-WB come standard with the module. These arms allow you to replace the module without disconnecting wiring. This feature reduces downtime during maintenance.
Expert Technical Evaluation & Performance Review
The 1771-HSN excels in high-speed information processing for large regulatory sequences. It commands servo axes via ±10 V DC analog outputs. The differential input captures pulses from 50 to 9.999 μs. This range gives fine control over acceleration and deceleration cycles. The update period of 2 ms per axis ensures tight loop closure. Engineers value this speed for applications needing processor coordination. The module integrates with PLC 5 controllers over DH+, ControlNet, or EtherNet/IP networks. Its 1.7 A backplane current places a low load on the power supply. The 1771-HSN is a Series B module, offering proven reliability. It occupies a single slot and supports two slots per ES module. This layout simplifies chassis planning. The module operates without a memory cartridge installed, but you must add one for configuration storage. This design keeps the base cost low while allowing flexible memory upgrades.
