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 mm2) wire.

	Frequency	47 to 63 Hz
	Input Impedance	28 kΩ ± 10% @ 25 °C (77 °F)
ACI1	Maximum Allowable	0–132 Vrms
ACI2	Voltage Range
ACI3
	Input to Guarantee On
ACI4		90 to 132 Vrms
	State
	Input to Guarantee Off	0 to 50 Vrms
	State a
Storage Temperature		-25 to 70 °C (-13 to 158 °F)

a.Coupling can cause voltages higher than 50 Vrms, which can turn the input on or prevent it from turning off.
