115 Vac Logic Input Module Typical Wiring
115 VAC Logic Input Module (VW3A58275U)
The 115 Vac logic input module, catalog number VW3A58275U, makes it
possible to use ATV58 TRX control terminal points LI1, LI2, LI3, and LI4 with
control circuits that require 115 Vac control. The module insolates the
115 Vac signals from the 24 Vdc input signals of the drive controller terminal
strip, without modifying the other signals.
The 115 Vac logic input module is designed for use only on the Type H and
Type N families of ATV58 TRX drive controllers. It requires no special
programming.
Drive controller logic inputs LI1, LI2, LI3, and LI4 retain their functionality
when using this module. These inputs correspond to the module inputs
labeled ACI1, ACI2, ACI3, and ACI4 respectively.
The figure at the left shows typical wiring using four switches, operating on
115 Vac, as inputs to the drive controller. Power is derived from a 115 Vac
power source wired to the switches, then to inputs ACI1–ACI4. The 115 Vac
common must be connected to the ACCOM terminal on the module.
See the table below for electrical specifications. The module accepts
26–16 AWG (0.14–1.3 mm
2
) wire.
